| 摘 要： | 以景天属植物费菜(Sedum aizoonL.)和长药八宝(Sedum spectabilisBoreau)为试材,通过盆栽控水处理,研究了水分胁迫对2种景天植株抗氧化保护酶活性的影响。结果表明:随着干旱胁迫的增强,费菜和长药八宝的超氧化物岐化酶(SOD)活性总体上表现为增加;过氧化氢酶(CAT)活性表现为先升后降;在轻、中度干旱胁迫下,费菜和长药八宝表现出一定的抗旱性。

| Abstract: | Taking Sedum aizoon L.and Sedum spectabilis Boreau as experiment material,the effects of water stress on the protective enzyme activities of two kinds of plant were studied,with water supply was controlled in potted materials.The results showed that:the activity of SOD was increased and the activity of CAT showed the variation trendency of falling after rising as the water stress was intensified.Sedum aizoon L.and S.spectabilis Boreau showed up certain resistance to drought under light and moderate drought ... |
