摘　　要：[目的]为明确从野生红小豆种群中筛选出来的红小豆品系"JH01"的高温胁迫响应。[方法]以红小豆品系"JH01"为试验材料,利用40℃进行胁迫处理,检测高温下红小豆品系可溶性蛋白含量、丙二醛(MDA)含量、质膜的相对透性、过氧化氢酶(CAT)活性、过氧化物酶(POD)活性、超氧化物歧化酶(SOD)活性的变化。[结果]经高温处理,红小豆品系叶片膜透性升高,SOD、CAT、MDA的活性增强,POD活性降低,而可溶性蛋白含量没有显著性变化。[结论]该研究为野生红小豆逆境生理研究与耐高温品系选育奠定基础。[ Objective] The research aimed to clarify the response of the wild adzuki bean line ＂JH01＂ under high temperature. [ Method] A adzuki bean line ＂JH01＂ as experimental material was treated by high temperature （40℃）. Its physiological and biochemical responses were measured, including leaf soluble protein content, malondialdehyde （MDA） content, plasma membrane relative permeability, catalase （CAT） activity, peroxidase （POD） activity and superoxide dismutase （SOD） activity. [ Result] Under the high temperature, plasma membrane rela- tive permeability, SOD activity, CAT activity and MDA activity increased, POD activity decreased, and soluble protein content didn＇ t significantly change. [ Conclusion] This study set up a foundation for the understanding of the stress-resistance mechanism and breeding of the wild adzuki bean line.
