abstract effect of different concentrations of salicylic acid on postharvest life of kiwifruit (actinidia deliciosa) cultivar hayward at 0 ±.5 °c and 90-95% rh was studied. fruits were treated with salicylic acid (0, 1 and 2 mmol/l-1) and stored at 0±.5°c for 16 weeks. fruit quality attributes assessment including firmness, total acidity, soluble solid content, ascorbic acid, antioxidant activi...
in order to evaluate the effect of different concentrations of postharvest salicylic acid and calcium chloride on shelf life, quality characteristics and antioxidant activity of peach fruit cv. amesden, an experiment was conducted as factorial based on randomized completely design with three replications. fruits were harvested at the commercial ripening stage, and fruits were immerged in differ...
This study was conducted to investigate the effects of different silicon supplements and postharvest treatments on growth and yield of gerbera in a greenhouse experiment. Silicon supplements were including potassium silicate at three concentrations (0, 140 and 200 mg L−1), sodium silicate at three concentrations (0, 50 and 100 mg L−1) and rice hull ash (RHA) at three concentrations (0, 50 and 1...
Salinity is the most important environmental stress that reduces plants growth and yield. It has been shown that salicylic acid, as an endogenous signal, is responsible for inducing stress tolerance in plants. In this experiment, the effect of salicylic acid and sodium chloride on growth of bean (Phaseolus vulgaris) was studied. When bean plants were at two-leaf stage, they were sprayed by thre...
Lily (Lilium longiflorum L.) is one of the most important potted flowers, which is used largely as cut flower. An experiment, arranged as a factorial besed on completely randomized dasign with three replications, was carried out to evaluate the effects of pre-harvest foliar application of humic acid, salicylic acid and calcium chloride on quality and longevity of lilium cut flowers. Treatments ...
effect of seed priming by salicylic acid and application of controlled water stress in flowering stage on some physiological characters such as relative water content, chlorophyll index, photosynthetic rates, transpiration rates, stomatal conductance, and leaf internal co2 concentration was investigated on cowpea (vigna unguiculata l. cv. parastoo) plants. experiment was done as a split block d...
Lime fruits has including economic and nutritional value but the fresh consumption of this fruit compare to processing methods is less, because of its low storage capacity. This research has been designed for study the effects of different concentrations of salicylic acid (0, 1, 2 and 3 mM) on quantitative and qualitative characteristics of lime fruit in storage period (0, 20, 40 and 60 days)...
in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
Extended abstract Introduction: Using of plant growth regulators is one of the methods can improve plant growth against environmental stresses such as salinity. Salicylic acid plays an important role in physiological processes regulation, including germination. Today, using of growth promoting bacteria has been increased and it causes to raise the seed vigor, uniformity, germination percentage...
wheat is one of the most important crops in the world that is constantly faced with the different biotic and abiotic stresses. programmed cell death is one of the methods for coping with different stress which is stimulated by several factors. because salicylic acid is involved in resistance to various stresses, to explore the effects of salicylic acid on programmed cell death, the effects of s...
