Effects of accelerated aging and seed priming treatments were studied on milk thistle seeds during germination process. Experiment was performed in a factorial based on Complete Randomized Design (CRD). Treatments were Salicylic acid concentrations (0, 500, 1000, 1500 and 2000 ppm) and accelerated aging for (0, 48, 96 and 144 hours under 45 °C and 95% humidity) with three replications. Our ...

introduction: pulsed dye laser (pdl) has been used to treat acne lesions and scar erythema by interrupting superficial vasculature. salicylic acid chemical peels are employed chiefly due to their lipophilic, comedolytic, and anti-inflammatory properties. although studies have looked at peels and laser therapy independently in acne management, we examined these treatments in combination. our pri...

The effect of three salicylic acid (0, 50 and 100 mg l-1) and K2SO4 (0, 0.1 and 0.2 %) levels on some characteristics nut and physiological parameters of pistachio trees cv. ‘Owhadi’ were investigated. Treatments were applied at endospermic growth stage of seed and cotyledons appearance. The results showed that potassium increase yield, splitting percentage; nut fresh mass and kernel dry mass a...

alstroemeria flower is one of the most important cut flowers in the world. some materials can increase longevity of cut flowers. the aim of this research was evaluating the effect of some chemical solutions on postharvest alstroemeria (cv. stratus) cut flowers. this experiment was conducted with two factors of sucrose at four concentrations, 0, 5, 10 and 15 g/l and salicylic acid (sa) at four c...

abstract in recent years some research results have appeared that exogenous salicylic acid provided significant mitigation effect against salinity induced injuries in plants. an experiment was conducted to investigate the effects of salt stress and salicylic acid on radish (raphanus sativus l.) plants. after appearing first leaves, plants were treated by salicylic acid (0.2 mm) for 3 days and n...

Temperature changes occur in nature faster than other stressors. Plants due to inability to move and change their position, are exposed to extensive variations in daily or seasonal temperature, and therefore, should quickly and effectively adapt to temperature stress. In order to study the effects of heat stress on physiological traits of forage maize hybrids, a factorial split plot experiment ...

cold stress is considered as a restricting factor in plant production. recently, many different compounds were applied to minimize the harmful effects of stress. in this study, the effects of foliar application of salicylic acid was studied on some biochemical properties of two different cold resistant canola cultivars. salicylic acid was sprayed at four concentrations (0, 100, 200 and 400 µm) ...

drought is one of the most important environmental factors which limit the growth of woody plants. iran is located in arid and semi-arid area therefore the growth and cultivation of ornamental trees and shrubs were limited. for this purpose, effect of foliar-applied salicylic acid and/or spermidine (0, 100, 500 and 1000 µmol) on reduce drought stress injuries of one-year seedlings ofosage orang...
