干旱胁迫对不同种源麻疯树幼苗生理特性的影响
Effects of Drought Stress on Physiological Characteristics in Seedlings of Different Jatropha curcas Provenances
摘要
Abstract
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.关键词
