  Background and Objective: Nowadays, heavy metal pollution has become a serious environmental problem. To protect the environment, one of the effective and low-cost methods is phytoremediation. Phytoremediation is the use of plants to remove, reduce and stabilize pollutants. In this regard, the use of fungi that symbiosis with plants, can increase the efficiency of phytoremediation, reduce the time required to remove contamination, and develop its application. Material and Methodology: This experiment was performed in order to investigate the traffic and symbiosis interaction’s effects on lead and cadmium accumulation in rosemary (Rosmarinus officinalis L.). The experiment donen in a randomized complete block design (RCBD) with three replications and three factors as factorial. The first factor includes mycorrhiza symbiosis (control and inoculation), the second factor was traffic (Control, 120, 300, 600, 950, 1200, 1800, 2400, 3000, 3600, and 4200 cars per hour) and the third factor was the type of pot (Controls and pots where the soil surface is covered except at the place of seedlings) with three replications in 2019-2020 in Shiraz metropolis. In the experiment some properties were investigated such as root weight, soil cadmium, shoot cadmium, root cadmium, stem length, main root length, plant dry weight, root lead, cadmium, and lead transfer factors. Findings: The results of mean comparisons showed that inoculation of plants with mycorrhizal fungi )Glomus mossea (had higher lead content of root tissue than shoots and soil in 4200 cars per hour compared to the control. Symbiosis with mycorrhiza fungi increased root weight and plant dry weight, stem length, and main root length compared to the control by 23.93, 18.97, 0.82 and 30.87% in 4200 car traffic per hour, respectively. The results also showed that the treatment of closed pots and inoculation of mycorrhizal fungi increased the growth parameters and decreased cadmium and lead. Discussion and Conclusion: The reduction of cadmium and lead concentrations in the inoculated rosemary with Glomus mosses indicates that Rosmarinus officinalis L. can grow in soils contaminated with cadmium and lead. Also, the symbiosis of mycorrhizae increases th ability of rosemary. Manuscript profile

  This study aimed to investigate the effects of two types of fungi on soybean function and morphology. This experiment was conducted in a factorial design with inoculation of two types of fungi, Trichoderma and mycorrhiza, at four levels: inoculation with Trichoderma, inoculation with Mycorrhizal, inoculation with both fungi, and the control, in three replicates. The experiment was performed in two crop years (2020 to 2022) in a research farm. After the physiological maturity of the parts, 10 shrubs from each treatment were randomly selected, and the macro- and micro-elements and the percentage of oil and protein were measured according to the standard method. Based on the results, chlorophyll a and b, the number of branches, dry weight, leaf area, pod length, stem diameter, number of pods per plant, number of nodes per stem, and height from soil to the first pod were higher in the soybean grown in soil containing double inoculation of the fungi than the other treatments and the controls. The yield was 1.98, 2.14, 2.85, and 1.7 tons per hectare, respectively. Protein content was 40.31, 42.74, 43.04, and 39.89%, and oil content was 2487, 25.24, 25.94, and 24.17%, respectively. The contents of macro- and micro-elements in soybean leaves and seeds were significantly higher in the biological fertilizer containing the two types of fungi than others. Given soybean's relatively wide area of cultivation in Mazandaran Province (Iran), the confirmed benefits of these fungi in improving the plant's growth and development, and the necessity of preserving production resources, the studied fungi can be a suitable alternative to chemical fertilizers.

  Deficiency of micro-nutrients in human diet may cause health problems. To increase the amount of these elements in the edible parts of the plants would eliminate the incidence of these health problems. Thus, the effects of iron and zinc on seed yield and morphological characteristics of mycorrhized barley (cv. Bahman) root was studied in Karaj, Iran, during growing season of 2013-14. It was carried out in afactorial experiment based on randomized complete block design with three replications. Treatments consisted two levels of mycorrhiza, non-inoculation (M0) and inoculation with 10 kg/ha of Glomus intraradices (M1), and three levels of iron from Fe-EDDHA (Sequestrene138) as control (F0), 2.5 kg/ha (F1) and 5kg/ha (F2) and three levels of zinc as zinc sulphate (ZnSO4) as control (Z0), 25 kg/ha (Z1) and 50 kg/ha (Z2). The results showed that application of mycorrhiza increased parameters like total root length (TRL), root length density (RLD), specific root length (SLR), root colonization percentage and grain yield by 900.6 cm, 0.52 cm/cm3, 1738.1 cm/g, 5.41% and 1ton/ha respectively. Mean comparisons also revealed that using iron, mycorrhiza and without Zn application increased levels of root dry weight (RDW) by 2.81 g. Manuscript profile

  Plant nutrition from different sources of fertilizers is one of the most critical factors for crop improvement under stress conditions. The purpose of this research was to study the morpho-physiological responses of the lemongrass (Cymbopogon citratus (DC.) Stapf) medicinal plant to the application of different fertilizer sources (control, NPK, nitroxin, mycorrhizal fungi, and biosulfur) under irrigation water salinity stress (0, 100, and 200 mM) in two climates (Fars and Tehran), implemented as a factorial split-plot based on a randomized complete block design in three replications during 2020-2021. Growth and yield attributes and also physiological traits such as photosynthetic pigments, proline content, and qualitative characteristics (essential oil percentage and yield) were measured. Results showed that high salinity concentration (200 mM) negatively affected growth and yield parameters (root dry weight and volume, plant height, number of leaves, and plant yield). The highest plant yield was obtained at 0 and 100 mM salinity with an average of 4183.1 and 4191.9 kg.ha-1, respectively in Fars. Among the fertilizer treatments, there was no difference in terms of plant yield, and all of them led to an increase in yield compared to the control treatment. Using nitroxin biofertilizer under non-stress conditions in Fars region led to the highest total chlorophyll and chlorophyll a, which showed an increase by 51.3% and 47.0%, respectively, compared to the control. Salinity stress (200 mM) and the use of biosulfur in Tehran climate led to an increase in proline content. The use of NPK fertilizer and mycorrhizal fungi under severe salinity stress in Fars led to increases by 2.3 and 2.4 times in essential oil percentage. The lowest average essential oil was also observed in the application of biological and chemical fertilizers in Tehran. The highest essential oil yield was obtained in the application of mycorrhizal fungi under moderate salinity stress in Fars, which was 2.7 times higher compared to the control. All fertilizer treatments at 200 mM level in Fars also had the highest essential oil yield. In general, the lemongrass plant had a good tolerance against the salinity stress of irrigation water and the use of NPK, nitroxin, and mycorrhiza fertilizers while increasing the quantitative and qualitative yield led to the adjustment of the adverse effects caused by the salinity stress.
