旱涝急转对不同花生品种生理生化指标的影响
Effect of abrupt droughts - floods on physiology and biochemistry of different peanut varieties
摘要
Abstract
Experiment was conducted to study the effect of abrupt droughts - floods on physiology and biochemistry in three peanut cultivars: Zhonghua 8 (drought resistant) , Yuhua 15 (waterlogging resistant) and Xian-ghua 2008 ( drought and waterlogging resistant) . After different gradient droughts - floods, the relative leaf water content, peroxidase (POD) activity, catalase (CAT) activity, superoxide dismutase (SOD) activity, glutathione oxidoreductase ( GR) activity and malondialdehyde ( MDA) content changes in three peanut cultivars were compared. Results showed that the effect of drought stress on relative leaf water content was greater than waterlogging. The activity of POD, CAT, SOD and GR increased under drought and waterlogging stress, but decreased under severe stress, then dropped to control level after restoring water supply. MDA content increased under drought stress stage then dropped to control level with water recovery; increased linearly under waterlogging stress stage, then decreased with released stress. There were significant differences in water adaptability in three peanut varieties. Zhonghua 8 showed better drought resistance than waterlogging resistance; Yuhua 15 showed better waterlogging resistance than drought resistance; Xianghua 2008 showed the best waterlogging resistance and better drought resistance, and was suitable for both moisture conditions.关键词
