Abstract

The maize seedlings were treated by different concentrations of exogenous salicylic acid in this experiment. Some of merphyoloyical and physiological characters of maize seedling were measured after treatment. The results showed that the growth and development of seedlings could be promoted after 1.5 mg/L treatment. The fresh weight and seedlings height were increased by 45.6% and 28.2% respectively. Also, Chlorophyll content, activities of SOD and POD were increased by 147.7%, 53.8% and 72.4%, respectively. The MDA and electrolyte leakage rate were decreased by 9.6% and 17.3%, respectively.
