Salicylic acid (SA), one of the plant phenolics is known to be involved in various physiological processes of plants such as flowering, seed germination, thermogenesis, stomatal regulation, fruit yield and disease resistance etc. The effects of exogenous SA (50, 500, and 1000 uM) on the thylakoid photo-function, status of various antioxidants, and phosphate uptake in wheat plants have been studied in the present work. Long-term treatment of SA (7 days) to wheat seedling affects its growth, leaf photochemical activities, including the phosphorylation efficiency, and thylakoid organisation. The...
