Effect of Short-term Exposure of Two Different Concentrations of Sulphur Dioxide and Nitrogen Dioxide Mixture on Some Biochemical Parameter of Soybean (glycine Max (l.) Merr.)
نویسنده
چکیده
The effect of elevated level of SO2+NO2 on some physiological and biochemical parameters of Glycine max were examined. Twelve days olds Soybean (Glycine max) seedling were exposed to two different (2% and 3%) levels of SO2+NO2 mixture. Fumigants were applied for 30 minutes per day, 3 days per week for 3 weeks duration. Aeration with enriched SO2+NO2 air resulted in higher phenolic content as compared to plants grown in control condition. However, reduction in leaf total carbohydrate, total protein and total chlorophyll were found in plants grown under elevated levels and the effect were more pronounced at 3% SO2+NO2 exposure as compared to 2% concentration.

Abstract: Jasmonic acid and its methyl ester, methyl jasmonate (MeJA), are naturally occurring plant growth regulators, which can affect many physiological and biochemical processes in plants. In present investigation, the effects of methyl jasmonate (0, 1, 10, 100 and 500µM) on some physiological and antioxidative responses in soybean (Glycine max L.) plants were studied. Under MeJA (1 and ...
