  BACKGROUND: The use of growth-promoting hormones and organic acids is one of the ways to deal with environmental stresses.OBJECTIVES: The present study was conducted to assess the effect of these treatments on saffron vegetative and reproductive traits, to use organic inputs properly, take steps towards sustainable production and increase quality of important medicinal plant.METHODS: Current research carried out via factorial experiment was conducted in Islamic Azad University, Isfahan (Khorasgan) Branch (2018-2019) in a completely randomized design with three replications. The treatments were control, Salicylic acid (1 and 2 mM), humic acid (15 and 30 mM) and Jasmonic acid (5 and 10 μM) with two salinity levels (1 and 4 ds.m-1). The evaluated traits included chlorophyll a, b and total chlorophyll, the number of flowers, flowering stem and leaves, petiole length, fresh and dry weights of leaves, stigma weight, and fresh weight of flowers.RESULT: The highest levels of chlorophyll a and total chlorophyll were belonging to humic acid 30 and control treatments under salinity 1. The highest amount of chlorophyll b was observed in humic acid 30 and control treatments under salinity 1 and salicylic acid 2 under salinity 4. The highest number and fresh weight of flowers were obtained from the control treatment under salinity 1. The tallest petioles and flowering stems were observed in Jasmonic acid10 under salinity1. The highest leaf length was belonging to salicylic acid2 under salinity1. The highest leaf fresh weight was belonging to salicylic acid2 under salinity1 whereas of Humic acid15 under salinity1 produced the highest dry weight of plant leaves. The highest stigma weight was observed in Jasmonic acid5 and the control under salinity1. As a result, application of plant growth regulators and humic acid can reduce effect of salinity stress in saffron.CONCLUSION: As a final conclusion of this study, it can be said that the use of growth-promoting hormones (salicylic acid) and organic acids (humic acid) under environmental stress conditions can improve morphological and vegetative characteristics such as chlorophyll and biomass produced in some plants such as saffron. تفاصيل المقالة

  Background & Aim: Sweet basil (Ocimum basilicum), a plant that is extensively cultivated in some countries, is used to enhance the flavour of salads, sauces, pasta, confectioneries and other products as both a fresh and dried herb. The effect of foliar application of Jasmonic acid and reduced irrigation on essential oil yield and chemical components of two Iranian landrace of basil (Ocimum basilicum) were investigated. Experimental: Treatments comprised control, 0.0, 200 and 400 µL Jasmonic acid applied to plants under normal irrigation and stressed conditions (30 and 60% F.C) based on a completely randomized design with three replications. The essential oils from the aerial parts of basil were analyzed by GC-FID and GC/MS. Results & Discussion: Results indicated that the different levels of Jasmonic acid and irrigation had significant effects on oil yield and some main components of the essential oil. The highest value of oil content was obtained from application of 400 µL JA. Percentage of some chemical constituents in the essential oil extracted from the plants under stress was higher than non-stressed plants. Foliar application of Jasmonic acid significantly improved methyl chavicol in the oils, but reduced Germacrene- D, α-Cadinol and δ-Cadinene amounts. Industrial and practical recommendations: Since, essential oil of basil, particularly methyl chavicol component, have many application in pharmaceutical and perfumery industry and has health benefits such as antiviral, antibacterial and antispasmodic activity, we can use Jasmonic acid elicitor to enhance the therapeutic properties of basil and also essential oil content and methyl chavicol of plant. تفاصيل المقالة

  Background & aim: Recent researches have been done on effects of plant growth regulators (PGR) on growth and production of different crops whose results indicate the effectiveness of most of these hormones on qualitative and quantitative growth of herbs. The application of regulators and inhibitors of growth on herbs may, in addition to growth, also lead to secondary metabolites stimulation. Jasmonic acid (JA) and its volatile methyl ester (MJ) collectively termed jasmonates, are regarded as endogenous regulators that play important roles in regulating stress responses, plant growth and development. This study was carried out to survey the effect of spraying of jasmonic acid (JA) on T. daenensis Celak in Shahrekord, Southwest Iran at 2010-2011. Experimental: A pot experiment was conducted in a CRD with six treatments and seven replications. The treatments including I: distilled water (control), II: distilled water and solution (acetone), III-VI: JA in various concentrations (50, 100, 200 and 400 µM). The treatments were applied before flowering stage. The aerial parts were characterized by Clevenger approach and Gas Chromatography–Mass Spectrometry. Results & discussion: Results of analysis of variance of the experiment showed that different levels of the foliar application of JA do have significant impacts on chemical constitutes in the essential oil of T. daenensis. Various concentrations of foliar application of JA caused decrease or increase some of secondary metabolites in essential oil. In comparison with other treatments, there is a significant difference between amount of thymol and carvacrol, as two main compounds in essential oil of T. daenensis, having 100 µM JA. The application of acetone solvent with distilled water also caused the increase in some of constitutes of the essential oil. Industrial and practical recommendations: In metabolic cultivation, for producing a special metabolite, the main agronomic and processing management should be regarded in order to increase the rate of essence and metabolites. Finally, some of secondary metabolite production in Thymus daenensis Celak could be partially changed by supplementation of different elicitors such as JA. تفاصيل المقالة

  Three separate experiments were conducted to investigate the interplay between three phytohormones and sucrose for the change of flower color composition and the plant secondary metabolites in Tulipa. The variations of the physiological and morphological characteristics, with ABA at 5 and 10 mg/L (as experiment one), GA3 at 300 &lrm;and 500 mg/L &lrm;&lrm;(as experiment two), 50 and 100 &micro;M of JA (as experiment three) and their interactions with sucrose at 1 and 2 g/L were analyzed. By reviewing the HPLC charts and UV-Vis spectra, it was found that the production of plant secondary metabolites, total flavonoids, and anthocyanins composition pigments was influenced by the foliar application of the plant hormones. The sucrose alone had no significant effect on the quantification of different phytochemicals, but the interaction with JA and ABA showed a considerable variation in the anthocyanin accumulation and total flavonoids. Both JA and ABA hormones, in spite of enhanced anthocyanin accumulation and increased cyanidin and pelargonidin pigment percentage, were associated with reduced vegetative growth parameters as well as vase life, compared to the control plants. However, GA3 at 500 mg/L without sucrose played a key role in the accumulation of anthocyanin, postharvest performance, and the increase in the three major anthocyanin pigments. Moreover, the data provided evidence of interference between the sucrose and GA3 in the regulation of the anthocyanin accumulation. تفاصيل المقالة

  Pistachio is one of the economically important horticultural crops in Iran. The main pistachio-producing areas in Iran are located at the edge of the desert and are affected by soil and water salinity. Water and nutrient uptake by the root decreases under saline conditions. In this study, the effects of foliar growth regulators applied at different times on the nutrient uptake and leaf nutrient content of pistachio trees were examined in accordance with a split-plot experimental design based on a randomized complete block design with three replications. The field experiment was conducted with a group of 30-year-old pistachio trees that have been exposed to water and soil salinity. Experimental factors included the timing of foliar application and the applied concentrations of plant growth regulators. The timing of foliar application was the main factor and was split into three levels: application on May 21th, June 21th, and May 21th + June 21th. Different concentrations of plant growth regulators, including sodium nitroprusside, salicylic acid, and jasmonic acid, were split into ten levels and were designated as the sub-factor. Results showed that the timing of application and the applied concentration of plant growth regulators affected root nutrient uptake and leaf nutrient content. The one-time application of plant growth regulators in June and the two-stage application of plant growth regulators in May and June resulted in the highest increase in leaf nutrient content compared with the control treatment. The application of low and moderate concentrations of plant growth regulators increased leaf nutrient content compared with the control treatment. High concentrations of plant growth regulators exerted no significant effects on leaf nutrient content. تفاصيل المقالة
