【摘要】Four different provenances of Jatropha curcas seedlings from Tianlin Guangxi, Xishuangbanna Yunnan, Luodian Guizhou and Dechang Sichuan were taken as test materials to study their cell membrane permeability, membrane lipid peroxidation( MDA), endogenous enzyme activity and soluble protein under natural drought. The results showed that: the membrane permeability in various sources of leaves and malondialdehyde (MDA) contents increased with the stress time extension; peroxidase (POD) and catalase (CAT) increased with the stress time extension and then decreased ,and reached the maximum on the 14th day; soluble protein decreased with the stress time extension and then increased and at last decreased. According to the comprehensive assessment of the values of membership function' the order of the drought resistance of the provenances of Jatropha curcas was: Dechang Sichuan ＞ Luodian Guizhou ＞ Tianlin Guangxi ＞ Xishuangbanna Yunnan.%以云南西双版纳、贵州罗甸、四川德昌和广西田林4个不同地理种源麻疯树盆栽幼苗为实验材料,研究其在自然干旱条件下细胞膜透性、膜脂过氧化、保护酶活性(POD、CAT)和可溶性蛋白质含量的变化规律.结果表明:各种源幼苗叶片质膜透性、丙二醛(MDA)含量随胁迫时间延长而增加;过氧化物酶
