To quantify the response of some morpho-physiological traits of Echinacea purpurea to thr application of zinc sulfate and ascorbic acid under water deficit, an experiment was carried out in split plot factorial based on RCBD with three replications at the Agricultural Research Station of Islamic Azad University, Tabriz Branch in 2011-12. Experimental factors consisted of water stress as the main factor with three levels (irrigation after70mm evaporation, irrigation after120mm evaporation and irrigation after 170mm evaporation from class A pan), Secondary factor consisted of: application of microelement with two levels (control and application of zinc sulfate 0.005 concentration) and ascorbic acid with four levels (not application, application of 50 mg/l of ascorbic acid, application of 100 mg/l of ascorbic acid and application of 150 mg/l of ascorbic acid). The results showed that the effect of water deficit on purple coneflower caused significant differences in diameter of stem, number of flowering branch, stomata density, zinc concentration of aerial parts plant, fresh weight, relative water content of leaf, LAI, proline concentration, crop growth rate, relative growth rate and net assimilation rate. Comparison of means for water deficits between the different levels of drought stress showed that the maximum LAI, with 2.85, belonged to control. Comparison of means for interaction effects between drought stress and application of zinc sulfate revealed that the maximum proline concentration belonged to spraying plants with zinc sulfate at irrigation after 170mm evaporation from class A pan with 10.16 mg/g.fw. Minimum proline concentration was due to without applying zinc sulfate in complete irrigation (control) with 0.08 mg/g.fw. Maximum crop growth rate with 6.77 g/m2.day was was related to control and the minimum, with 4.16 g/m2.day, to irrigation after 170mm. Maximum relative crop growth rate, with 0.19 g/m2.day, belonged to control and the minimum, with 0.14 g/m2.day, to irrigation after 170mm. Maximum net assimilation rate, with 2.64 g/m2.day, belonged to control and the minimum, with 1.91 g/m2.day, to irrigation after 170mm. The results indicated that application of ascorbic acid, as an antioxidant, may decrease the harmful effects of drought stress on some traits (NAR, CGR, RGR, and RWC) of purple coneflower.  Manuscript profile

To investigate the effect of water deficit stress and stress modifiers on the nutrient concentration of leaf and grain and biochemical characteristics of quinoa, a pot factorial experiment based on a completely randomized design with 16 treatments and 6 replicates was done in 2019 at Urmia University. The first factor includes water deficit stress at four levels (stress at vegetative growth stage, after plant establishment to flowering; stress at reproductive growth stage, from flowering to flowering end; stress at grain filling stag, from the beginning of filling to maturity; no stress, control) and the second factor is foliar spraying at four levels (ascorbic acid, 2 mM; salicylic acid, 2 mM; nano-micronutrient chelate fertilizer, 2 liters/1000 L water; control, water spray). The results showed that dehydration stress had a significant effect on leaf and grain elements and biochemical traits. Dehydration at different stages of growth reduced chlorophyll a and b, carotenoids and soluble sugars compared to the control but proline content increased. Mean comparison showed dehydration stress in vegetative growth stage, reproductive growth stage and dehydration stress in grain filling stage compared to control (without dehydration stress) increased proline content by 15%, 28% and 31%, respectively. However, dehydration stress at vegetative growth stage, reproductive growth and grain filling stage reduced grain weight by 4, 20 and 20%, respectively, compared to the control (without dehydration stress). Foliar application by increasing proline accumulation and photosynthetic pigment content, increased quinoa grain weight. Foliar application of ascorbic acid, complete micro-nanofertilizer and salicylic acid increased the chlorophyll a content by 2, 13 and 5%, respectively, compared to the control (spraying), respectively. It seems that foliar application of salicylic acid had a more positive effect than other modifiers at different stages of dehydration. Manuscript profile

The objective of this research was to determine the effect of ultrasound treatment on bioactive compounds (including total phenolic, total flavonoids, total carotenoids, ascorbic acid) of carrot juice in comparison with conventional thermal process. Carrot juice samples were sonicated according to D-optimal response surface design with processing variables of temperature (25, 37.5 and 50°C), time (10, 20 and 30 min) and power (350 and 400 w) at a constant frequency of 24 kHz. Results showed that ultrasound temperature (P<0.01), time (P<0.01) and power (P<0.05) significantly decreased the ascorbic acid content of carrot juice samples. Ascorbic acid contents in heat-treated and sonicated samples reveled that sonication process had more protective effect of ascorbic acid. Ultrasound temperature significantly (P<0.05) increased the total carotenoid contents of the sonicated samples. On the other hand, ultrasound duration significantly (P<0.01) decreased the total phenolic contents of the sonicated samples; nevertheless, no significant difference was observed between sonicated and heat-treated as well as control groups. Total flavonoids content of the sonicated samples was significantly (P<0.01) decreased in comparison with the heat-treated and control samples. It was concluded that ultrasound treatment as a non-thermal preservation technique, leads to better retention of bioactive compounds (especially ascorbic acid, total carotenoids and total phenolic contents) compared to thermal process.

Due to accumulation of lead in edible tissues of fish, the safety and health of human food are also affected. This study was conducted to compare the effects of ascorbic acid and thiamine in prevention of lead induced tissue damages in selected tissues of common carp (Cyprinus carpio). Fish were divided randomly into 4 groups of 30 fish each. Group 1 was considered as control group. Group 2 received lead acetate while groups 3 and 4 received thiamine and ascorbic acid respectively in addition to lead. After necropsy, tissue specimens were collected from the brain, kidney and liver and the processed slides were stained with hematoxylin and eosin. Brain lesions in group 4 consisting of hyperemia, edema and ischemic cell changes were significantly lower in comparison to groups 2 and 3. In liver, hyperemia, hyperplasia of melano-macrophage centers, hepatocellular degeneration and intranuclear acid-fast inclusion bodies were observed. The severity of hyperemia and degeneration in group 3 was significantly lower in comparison to group 4. In the statistical comparison, none of the renal pathological indices including hyperemia, hemorrhage, intranuclear acid-fast inclusion bodies, necrotic changes, swelling of epithelial cells and hyperplasia of melano-macrophage centersrevealed significant differences between groups 3 and 4  but compared to group 2, some lesions in these groups showed a significant difference. Based on the results, it can be concluded that ascorbic acid and thiamin might have some protective and therapeutic effects on lead poisoning in fish. Manuscript profile

     The aim of this study was to evaluate the athletic performance of Arab horses fallowing oral administration of ascorbic acid. The study was conducted on two groups each consisting of 20 Arab horses with the age range of 4-9 years and body weight of 450-550 kg. After general examination of all horses, those in the treatment group received 20 grams of oral ascorbic acid daily for 30 days. At the end of 30 days period, general examination was performed once again and two jugular blood samples along with the electrocardiography after exercise at the 2160 meter track. Statistical analysis of the results indicated that the mean serumic levels of aspartate aminotransferase, lactate dehydrogenase, creatine phosphokinase, lactate and uric acid had significantly increased (p<0.05) fallowing exercise in both control and treatment groups but the mean serumic levels of ascorbic acid had decreased (p<0.05) fallowing exercise in both groups. Average heart rate had also significantly increased (p<0.05) after exercise. Abnormal electrocardiographic changes were not seen in any of the cases. Considering the significance difference (p<0.05) in mean creatine phosphokinase and lactate levels fallowing exercise between the control and treatment groups, it can be concluded that the administration of ascorbic acid improves the athletic performance of Arab horses.

In order to investigate the effects of vitamins C and E and betaine on performance, immune response and blood parameters of broiler chickens, an experiment was conducted with completely randomized block design consisting of 6 treatments and 5 replicates with 30 chicks in each replicate. The groups were assigned to receive the treatment diets as follows: diet with no feed additive (control); diet supplemented with vitamin C; diet supplemented with vitamin E; diet supplemented with betaine; diet supplemented with vitamin E and betaine; diet supplemented with vitamin E, vitamin C and betaine. Body weight, feed intake, body weight gain, feed conversion ratio and mortality were determined over the course of the experiment. At 35 days of age, two birds per replicate were randomly selected and 2 ml blood sample was collected to measure plasma concentration of T3 and T4 hormones. IgM and IgG antibody response to SRBC were also determined at 28 days of age. Body weight, FI and FCR were not affected by different treatments over the course of the study. Broilers fed diet supplemented with vitamin C, vitamin E and betaine showed the highest survival percentage and production index as compared with the other treatments. But it was not significantly different with the control group. IgM and IgG antibody response to SRBC, hematocrit percentage and plasma concentration of T3 and T4 also were not affected by different dietary treatments. The results of this experiment showed that there were no significant differences among the treatments in the performance, immune response and blood parameters of broiler chicken. Manuscript profile

In recent years, increasing attention has been paid by consumers to cornelian cherry fruit, which is rich in antioxidants. This research was carried out based on a randomized complete block design for evaluation of the variations in some quantitative and qualitative properties of cornelian cherry fruits during the last stages of maturation in 2015. Fruits were harvested at 4 different times and from 4 main geographical directions of the tree and were then immediately transferred to the laboratory. Several parameters such as dimension (length and width), weight, firmness, pH, total soluble solids (TSS), total titratable acidity (TA), TSS/TA ratio, ascorbic acid (vitamin C), total phenolic compounds, total flavonoids, total anthocyanins, and total antioxidant capacity of the fruits were investigated. The results showed that the effect of different harvest dates on all traits was significant (P<0.05) while no significant differences were observed between replications. During fruit ripening, weight, dimension, pH, TSS, TSS/TA ratio, total flavonoids, and total anthocyanins increased while firmness, TA, total phenol, and total antioxidant capacity decreased. The content of ascorbic acid increased during fruits ripening, but it reduced again in the last harvest. The results indicate that the third harvest time (16.63 Brix level) can be the best harvest date for this genotype. Manuscript profile

Salicylic acid (SA) is an antioxidant which has been used in recent years to increases the resistance of plants to deal with stresses. In this study 5 weeks after germination, different concentrations (0.1, 0.7, 1.5, 3, 6 and 9 mM) of salicylic acid application were investigated on germination, shoot and root length, anthocyanin, reduced sugars, protein, ascorbic acid, dehydroascorbic acid and proline in pepper. The results showed that under experimental conditions concentrations of 0.1, 0.7, 1.5 and 3 mM of SA increased germination, shoot and root length, but 6 and 9 mM of SA concentrations decreased germination percent, shoot and root length. Concentrations of 1.5 and 3 mM of SA decreased ascorbic acid and dehydroascorbic acid content, but concentrations 6 and 9 mM of SA increased ascorbic acid and dehydroascorbic acid content in the leaf of pepper plant. Concentrations of 1.5 and 3 mM SA caused significant increase in sugars and protein content in treated leaf but 6 and 9 mM of concentrations SA decreased sugars and protein content. Also, other research findings showed that under experimental conditions, different concentrations (0.7, 1.5, 3, 6 and 9 mM) of SA increased content of anthocyanin and proline in the leaf of pepper plant . In general, treatment of SA low and height concentrations has positive and negative effects on plant growth on the growth of the pepper plant, respectively. Manuscript profile

In order to investigate the effect of foliar application of ascorbic acid on the activity of antioxidant enzymes in mung bean (Vigna radiate L.) under water-deficit stress, a field trial was performed in a split-plot design arranged in completely randomized block design with three replications in the Education and Research Center of Natural Resources Safiabad, Dezful during the two cultivation years (2017 and 2018). Four levels of water-deficit stress treatments were considered in the main plots (25, 50, 75, and 100% of plant water requirement) and combined treatment of foliar application of ascorbic acid in three levels (control, 10, and 20 mM) and genotype including Omidbakhsh VC6173 and Partow cultivars as subplots. The results of mean comparison showed that the highest levels of superoxide dismutase and ascorbate peroxidase were observed in water-deficit stress of 25% water requirement and no foliar application of ascorbic acid. The highest activity of catalase enzyme was observed under water-deficit stress of 50% water requirement and no foliar application of ascorbic acid. Also, the highest activity of guaiacol peroxidase enzyme was observed in Omidbakhsh VC6173 cultivar under water-deficit stress of 25% water requirement and no foliar application of ascorbic acid. The highest glutathione peroxidase activity was observed in VC6173 cultivar under water-deficit stress of 75% water requirement and 10 mM foliar application of ascorbic acid. Results showed that dehydration stress significantly increased the activity of antioxidant enzymes while foliar application of ascorbic acid due to its antioxidant properties reduced the effects of stress and thus reducing the activity of antioxidant enzymes Manuscript profile

Biostimulants originate from natural and biological sources and in addition to improving plant growth and soil yield, they can protect plants from environmental stresses and stimulate the synthesis of secondary metabolites involved in plant defense mechanism. In this study, to study the effect of foliar application of various amino acids on the biochemical responses of Physalis alkekengi L. an experiment in the form of randomized complete block design with 3 replications in the farm of research Institute of Medicinal Plants of jahad University in Karaj was conducted in the cropping year of 2018-19.Treatments at five levels of amino acid foliar application including {control (A0), tryptophan (1 mg/L) (A1), glycine (1 mg/L) (A2), tyrosine (1 mg/L) (A3) and arginine (1 mg/L) (A4) were administered. Measured variables included: carotenoids, anthocyanins, proline, phenol, beta-carotene, lycopene, ascorbic acid, and alkaloids. The dimensions of the plots were 3×3 m, the distance between each plot was considered to be one meter. Planting operations were done manually in May 2017. The distance between the plants on the culture lines was 25 cm and the distance between the culture lines was 60 cm. Foliar spraying on plants began before flowering. At the time of sampling, three replicates were taken from each treatment and three samples were taken from each replication. Chlorophyll and carotenoids by Lichtenthaler method, anthocyanin by Mita method, proline by Bates method, phenol by Meda method, beta-carotene by Amarowicz method, lycopene by Montesano method, ascorbic acid by titration method, and alkaloid by Iranian Herbal Pharmacopeia method, were measured. The results showed that foliar application of amino acids had a significant effect (p ≤ 0.01) on all evaluated traits and the highest amounts of carotenoids (12.83 mg/gfw), beta-carotene (0.035 mg/gfw), and lycopene (0.017 mg/gfw) from arginine foliar application, highest ascorbic acid (24.2 mg/gfw) and alkaloids (42.25%) from tryptophan foliar application, highest proline (1.4 mg/gfw) Glycine and the highest levels of anthocyanin (12.25 mg/gdw) and phenol (32.44 mg/gfw) were obtained from the control treatment (no foliar application). In general, the results showed that foliar application of amino acids as a biological stimulant had a positive effect on improving the quality characteristics of the Physalis alkekengi L and increased the production of biochemical compounds of the plant.

In this study the effect of preliminary ascorbic acid soaking treatments with two concentration 100 and 300 mg on the microbial growth and rancidity development in common carp fillet during refrigerated storage (4±1ºC) up to 21 days was investigated. Microbial analysis including total viable counts and psychrophilic bacteria counts as well as the peroxide, total volatile basic-nitrogen, free fatty acids, thiobarbituric acid and pH were periodically measured every 7 days during storage period. According to the results, the treated sample with 300 mg ascorbic acid significantly reduced the total viable counts as well as psychrotrophic bacteria counts in comparison to other groups (p<0.05). The maximum and minimum amounts of peroxide value was calculated in the control (6.113±0.471 meq/kg) and 300 mg of ascorbic acid (3.933±0.045 meq/kg), respectively (p<0.05). The amount of total volatile base nitrogen was controlled just in 300 mg of ascorbic acid treatment than other treatments at the end of storage day (p<0.05). Increasing trend of thiobarbituric acid was  significantly inhibited in 300 mg ascorbic acid treatment compared to control group during storage (p<0.05). The maximum value of free fatty acids (FFA) was obtained in the control (18.378±0.966%) (p<0.05), while the amount of  FFA in 100 and 300 mg of ascorbic acid treatments were reached 9.967±0.911%  and 7.017±0.267%, respectively. Results of bacterial and chemical analyses showed that bacterial growth and formation of primary and secondary lipid oxidation compounds were controlled by increasing ascorbic acid concentration which was corroborated by a longer shelf-life time.

Alicyclobacillus acidoterrestris (A. acidoterrestris) is a thermophilic spore-forming bacterium that changes taste and smell of juices. The aim of this study was to investigate the inhibitory effect of nisin and ascorbic acid on A. acidoterrestris. Nisin (150 and 200 ppm) and ascorbic acid (100 and 250 ppm) were used in orange juice contaminated with A. acidoterrestris. Microbial, physicochemical, and sensory properties of the samples were investigated during 90 days’ storage. Adding nisin and ascorbic acid significantly (P<0.05) decreased the number of A. acidoterrestris in orange juice. The sample containing 200 ppm nisin+250 ppm ascorbic acid and the sample containing 200 ppm nisin+100 ppm ascorbic acid had the lowest number of A. acidoterrestris, respectively. During storage, the number of bacteria in samples containing nisin and ascorbic acid decreased significantly (P<0.05) so that no bacterial growth was seen in the sample containing 200 ppm nisin and 250 ppm ascorbic acid on the 60th and 90th days and the sample containing 200 ppm nisin+100 ppm ascorbic acid on the 90th day. Acidity of the samples increased and brix decreased significantly (P<0.05) during storage. The sample containing 150 ppm nisin +100 ppm ascorbic acid and the sample containing 200 ppm nisin +100 ppm ascorbic acid had the highest score of overall acceptance. The sample containing 200 ppm nisin +100 ppm ascorbic acid was selected as the best sample with regard to microbial and sensory properties. Therefore, orange juice containing nisin and ascorbic acid has suitable sensory quality and can affect the inhibition of A. acidoterrestris. Manuscript profile

With the aim of facilitating the harvest and accelerating the formation of the separator layer of the fruit with the peduncle, an experiment was conducted with ascorbic acid as one of the synergists of ethylene. This experiment was conducted in the form of randomized complete blocks in 3 replications and 8 treatments based on the concentration of ascorbic acid. The present study showed: a significant difference was observed between the design blocks. However, in statistical calculations, ascorbic acid did not show a significant effect on the separation of fruits, but according to observations, the use of ascorbic acid accelerated and increased the production of ethylene in the plant, so that at a concentration of 2500 ppm, the lowest force to separate the fruit from the branch we experienced. In other words, the direct use of ascorbic acid on the fruit-bearing branch with the appropriate concentration was not ineffective in facilitating the separation of the fruit from the tree, and it requires more repeated experiments. To facilitate the separation of mesocarp from endocarp, acetylene gas was used as one of the synergisms of ethylene. The experiment was conducted as a randomized complete block design with 3 replications and 4 treatments based on acetylene concentration. This study showed that acetylene gas has a significant effect on the ease of walnut mesocarp separation by accelerating fruit ripening. As a result, by using this gas as an ethylene synergy, a higher percentage of quality nuts and walnut kernels with a bright color are obtained. Manuscript profile

The present study was aimed at investigating the effect of ascorbic acid and methionine hydroxy analogue (MHA) on performance and liver histology of broilers under heat stress conditions. To perform the experiment, 400 one-day-old male chickens of commercial Ross 308 strain were used in a completely randomized design with four treatments and five iterations (each iteration contained 20 chickens). The experimental treatments included: 1) base diet based on maize-soybean (the control), 2) base diet with 0.2% vitamin C, 3) base diet with 0.46, 0.36, and 0.32% MHA, in the starter, grower, and finisher periods, respectively, and 4) base diet with a mixture of 0.2% vitamin C and 0.46, 0.36, and 0.32% of MHA in the starter, grower, and finisher periods, respectively. During the growth period, feed consumption in the treatment containing MHA had a significant increase compared to the control group (P <0.05). In the final period, feed conversion ratio in treatments using a mixture of vitamin C and MHA had a significant improvement compared to the control group (P <0.05). Hepatocyte diameter and hepatocyte nucleus diameter were significantly reduced in chickens receiving vitamin C and a mixture of vitamin C and MHA compared to the control group (P <0.05). The results of this experiment revealed that the use of a mixture of vitamin C and MHA compared to their separate use in the diet could be effective in reducing the negative effects of heat stress.   Manuscript profile

Breast cancer is one of the most common types of cancer in women. Today, researchers are looking for new ways to treat cancer. One of the investigated approaches in the field of cancer is the use of stem cells. This study aimed to evaluate the proliferation and survival of 4T1 breast cancer cells in the presence of conditioned medium (CM) of mesenchymal stem cells treated with ascorbic acid (AA). Human adipose-derived mesenchymal stem cells (h-ADMSCs) and 4T1 breast cancer cells were used in this study. 4T1 cells were treated with different concentrations of AA and their viability was checked by MTT test. According to the results of previous studies and MTT test, 1 mM concentration was chosen to collect CM from h-ADMSCs. h-ADMSCs were divided into four groups: groups without FBS with and without AA (-FBS/± 1 mM AA) and groups containing 5% FBS with and without AA (5% FBS/± 1 mM AA). Then, the survival rate, colonization potential, cell cycle profile and apoptosis rate of 4T1 cells treated with different CMs were investigated. The results showed that CM in the -FBS/+AA group causes a decrease in the viability and proliferation of 4T1 cells compared to the -FBS/-AA group. Also, CM in the groups with FBS also showed similar results and the FBS/+AA group +5% decreased the survival and cell proliferation of 4T1 cells compared to the FBS/-AA+5% group. Also, CM caused changes in the cell cycle profile of 4T1 cells and their apoptosis rate in the studied groups. According to the results, it seems that ascorbic acid can decrease the survival and proliferation of 4T1 breast cancer cells by affecting the CM compounds obtained from h-ADMSCs. Manuscript profile

In order to study the effects of water deficit stress and foliar application of ascorbic acid, an experiment was conducted in research field of Islamic Azad University, Varamin Branch in Iran during 2012 growing season. The experimental design was laid out in a randomized complete block design with a split plots arrangement in three replications. Main plots included four different levels of irrigation (complete irrigation, irrigation withholding at 8-leaf stage, irrigation withholding at grain filling stage and irrigation withholding at both 8-leaf and grain filling stages) and three different concentration of Ascorbic Acid foliar application (0, 100 and 200 ppm) was allocated to subplots. The results showed that irrigation withholding conditions in different growth stages significantly decreased seed yield, biological yield, harvest index, oil and protein percentage, oil and protein yield and total chlorophyll content but by contrast increased proline content and superoxide dismutase activity in leaves. Foliar application of ascorbic acid as antioxidant enzyme could increased quantitative and qualitative yield and chlorophyll content and decreased proline and superoxide dismutase activity in leaves by reduction of water deficit stress. Foliar application of Ascorbic Acid with 200 ppm under irrigation withholding at both 8-leaf and grain filling stages increased 38/46% yield seed compared with treatment that foliar application without Ascorbic Acid. In addition, Ascorbic Acid foliar application reduced the harmful effects of water deficit stress as antioxidant and improved growth conditions for water deficit stress.   Manuscript profile

In order to study the effects of seed priming with ascorbic acid (AsA) on agronomic traits of two soybean cultivars under normal irrigation and interrupted irrigation at flowering stage, this experiment was carried out in a split-plot factorial arrangement with randomized complete block design in three replications at the research farm of agriculture faculty, Islamic Azad University, Sanandaj Branch in 2013. The main factor was irrigation with two levels of full irrigation and interrupted irrigation at flowering stage. The factorial combination of cultivar and seed priming with AsA was assigned in sub-plots. Two soybean cultivars included Hobbit and L17 and seed priming treatments included: 0 (Control or non-priming), 50, 100 and 150 mg/L AsA. Results showed that two soybean cultivars differently responded to seed priming with AsA under full irrigation and interrupted irrigation (drought stress). Hobbit cultivar positively responded to priming under stress conditions. AsA application in seed priming resulted in increasing of seed yield and seed oil yield in comparison with control (non-priming), whereas L17 cultivar had no response to seed priming in stress conditions. On the other hand in normal irrigation conditions two cultivars showed a reverse reaction to seed priming so that L17 cultivar positively responded to priming under full irrigation conditions especially the concentration of 150 mg/L AsA expressively increased seed yield of this cultivar Manuscript profile

Identifying the critical time and timing of plant irrigation based on a precise and basic plan is the key to water conservation, improvement of irrigation operations and plant tolerance to water shortage in agriculture. In recent years, vesicular arbuscular mycorrhizal fungi have been used in many plants to deal with dehydration and drought stress. In this regard, an experiment was conducted as split-plot in the form of randomized complete block design with 3 replications in the Yasuj region at years 2015 and 2016. Water stress was considered as the main factor in the form of irrigation after 30, 60, 90, 120 and 150 mm of evaporation from the evaporation pan class A and mycorrhizal fungus was considered as a secondary factor in the form of no application, application of Glomus mosseae and application of Glomus intraradices. The results showed that the interaction of irrigation and mycorrhizal fungi on flower phosphorus, flower yield, biological yield and water use efficiency of Borage was significant. In irrigation levels after 60, 90, 120 and 150 mm of water evaporation from the evaporation pan, the use of mycorrhizal fungi Glomus mosseae and Glomus intraradices compared to the absence of fungi respectively increased the yield of plant flowers (30.04% and 27.35 %), (90.2% and 90.98%), (93.21% and 94.1%) and (81.73% and 78.86%), also, at these levels of irrigation, biological yield and water use efficiency of Borage flower achieved a significant increase in the presence of mycorrhizal fungus, compared to the absence of mycorrhizal fungus application. Application of both strains of mycorrhizal fungus Glomus mosseae and Glomus intraradices in irrigation levels after 90, 120 and 150 mm of water evaporation from the evaporation pan compared to no application of mycorrhizal fungus, respectively, resulted in a significant increase in the harvest index of Borage flower (44.55% and 43.36%), (13.21% and 15.96%) and (5.6% and 5.41%) and flower phosphorus (44.69% and 20.45%), (150% and 125%) and ( 267.74% and 235.48%). Mycorrhizal fungus was able to moderate the negative effects of drought stress and increase the above-mentioned traits in those irrigation levels, and based on the results of this study, irrigation treatment after 90 mm of water evaporation from the evaporation pan + the use of Glomus mosseae mycorrhizal fungi is recommended.
