abstract
Increasing composition of gaseous pollutant derived by anthropogenic activity disturbed natural atmospheric gaseous composition and deplete the stratospheric ozone layer. Major consequences of this depletion are increase incidents of harmful UV-B radiations reaching to terrestrial surface. Plants being permanent tool to removed harmful effect of solar radiation. Plants use sunlight as primary energy sources, therefore the small increase in UV-B radiation is recognized as harmful for plants. Many studies have shown that solar UV-B radiation causes significantly effect on morphological, physiological and yield components the plant. Therefore the present study conducted for assessment of relative effectiveness of Ascorbic acid, Salicylic acid and orange juice on soybean cultivar (Glycine Max. L.) under temperature acclimated UV radiation stress. Resultants ambient UV-B radiation caused harmful effect to soybean cultivar and reduce plant biomass 36% at juvenile stage and 40% at vegetative stage as compared to UV-B filter treatment. The effectiveness of Ascorbic acid, Salicylic acid and orange juice was following the trends 40% OJ > 20% OJ > 50 ppm AA > 100 ppm AA > 100 ppm SA > 50 ppm SA as compared to control plant. Based on obtained results orange juice and synthetic ascorbic acid will be useful tool for assessment of harmful effect of UV-B radiation on plants.
