SA与Ca2+处理对皖贝母耐热性的影响
Comparative Study on Effects of SA and Ca2+ Treatment on Heat Tolerance of Fritillaria anhuiensis
摘要
Abstract
The effects of single and combined applications of SA and Ca2+ on the related physiological indexes of FritiUaria anhuiensis leaves under high temperature stress were studied through pot experiment. The results showed that: in the treatment of spraying 0.5 mmol/L SA solution, the number of yellow leaves was the least, the activity of antioxidant protection enzymes ( SOD, POD, CAT, APX) and the content of proline (Pro) , soluble sugar and malondialdehyde (MDA) in the leaves were the highest, and this treatment appeared the restraint to catalase ( CAT) activity. In the treatment of Ca2+ , CAT activity was the highest. These three treatments all could improve the tolerance of FritiUaria anhuiensis to high temperature stress, and reduce the harm caused by high temperature stress. Among three treatments, spraying 0.5 mmol/L SA solution showed the best effects.关键词
