干旱胁迫对玉米幼苗根系几个生理生化指标的影响
Effects of Drought Stress on Several Physiological and Biochemical Indexes of Maize Seedling Roots
摘要
Abstract
The changes of several physiological and biochemical indexes of seedling roots of new maize variety Qingnong 8 were studied under the simulated drought conditions through water shortage and 18%PEG-6000.The results showed that under drought condition, the content of soluble protein, malonialdehy ( MDA) and the activity of superoxide dismutase ( SOD) and peroxidase ( POD) in roots of maize seedlings significantly increased, and the increasing amplitude reduced after water shortage for 96 hours.The re-wate-ring treatment results after water shortage for 48 hours showed that the SOD and POD activities and the MDA content could recover to normal level, and the soluble protein content was lower than normal content.This study showed that the maize seedlings of Qingnong 8 suffered drought injury could grow normally after re-wa-tering treatment.关键词
