7种冬青对苯气体胁迫的生理响应
The physiological responds of seven Ilexs to benzene stress and their benzene resistance capacity
摘要
Abstract
Physiological characteristics of seven Ilexs were investigated under artificial simulation of benzene gas stress, in order to unveil the possible mechanisms of them in response to benzene stress. The results showed that membrane per⁃meability, chlorophyll a/b, content of the lipid peroxidation product ( malondialdehyde, MDA) , content of proline in⁃creased, the content of soluble sugar decreased with the extension of the stress time. Meanwhile, SOD activity and POD activity present a downward trend after rising first.The order of benzene tolerance of seven tested Ilexs decreased was:I. meserveae ‘blue girl’, I.dabeishannensis,I.crenata,I. bioritsensis,I. alt ‘golden gem’,I. chinensis.关键词
