镉胁迫对花生叶片衰老的影响
Effect of Cd Stress on Leaf Senescence of Peanut
摘要
Abstract
Pot experiment was carried out to study the effect of Cd stress on leaf senescence of peanut cultivars of Yuhua15 and XB023. The results showed that there was almost no effect of Cd on peanut leaves chlorophyll content, photosynthetic rate and activity of protective enzymes under a condition of 1.00 mg/kg. The Cd stress didn't cause leaf senescence. Cd obviously decreased Yuhual5 leaves chlorophyll content, photosynthetic rate, increased the activity of SOD, POD and CAT under a condition of 2.50 mg/kg, and Yuhual5 was senescence. Cd obviously decreased XB023 leaves chlorophyll content, photosynthetic rate, increased the content of MDA under a condition of 7.50 mg/kg, and XB023 was senescence. Compared with XB023, Yuhual5 was easier to be senescence under Cd stress.关键词
