Drought stress is considered as a restricting factor in plant production and salicylic acid (SA) has been reported to minimize the harmful effects of many stresses including drought. In this study, salicylic acid was sprayed on the leaves of Brassica napus at the 4-leaf stage at concentrations of 0.5, 1 and 1.5 mM for two days. Plants were subjected to drought stress (withholding water for five...

Effects of salicylic acid (SA) on seed germination, seedling growth, flowering and biochemical activities were studied out in four cowpea (Vigna unguiculata) genotypes in control environments. The results revealed that both germination and seedling growth were negatively affected by 0.02%. SA application, however did not affect the size of full expanded buds, time of 50% flowering and date of f...

as seed germination of guava (psidium guajava) is poor and time-consuming, the effects of seed extraction technique and scarification methods on the seed germination and seedling growth of guava cv. allahabad safeda, were investigated. first experiment was conducted on extraction of guava seeds using sulfuric acid (h2so4) : seed ratios including: 1:5, 2:5 and 3:5) or manual extraction (control)...

Melissa officinalis is a perennial herbaceous plant from Lamiaceae family, widely used in food and pharmaceutical industries to add aroma. Drought stress in plants may happen due to the increase in water loss, insufficient water absorption or both. Salicylic acid (SA) is an important secondary metabolite in plants with hormone-like action in some biochemical pathways. Adding it during water-def...

Background: Medical plants production, including borago, is for maximum productivity from their effective ingredients’. Flowers, leaves and seed oil are medical parts of borago. Unfortunately, because of little breeding and domestication programs in medical plants, including borago, their establishments are usually slow. One of the effective techniques for solving this problem is seed priming. ...

Effect of salicylic acid combined with glutamin on rose (Rosa Baccara) cut flowers was studied. The study was conducted in a factorial arrangement, carried out in a complete randomized design. The factors were Salicylic acid (0,1, 2 and 4 mM) and glutamin (0, 1.5 and 3 mM).The effects of treatments on the total chlorophyll content, ACC-Oxidase activity, anthocyanin leakage, membrane stability a...
