| 摘 要： | 采用聚乙二醇(PEG6000)胁迫,研究了干旱胁迫条件下麻疯树幼苗叶组织中抗氧化系统的变化.结果表明:在0～60 h胁迫中,麻疯树幼苗叶片相对含水量(Rwc)明显下降;处理36 h内,丙二醛(MDA)含量略有增加,但增幅不大,叶绿素含量增加;处理36 h后,MDA含量大幅增加,叶绿素含量逐渐下降;抗坏血酸(ASA)含量...

| Abstract: | Stress with polyethylene glycol(PEG)6000 is carried put to study the change of anti-oxidation system roe the leaf of Jatropha curcas L..The results indicates that the relative water content(RWC) greatly declined during the 0~60 h stress.Malondialdehyde(MDA) content remains stable with little increase,but the content of chlorophyll increases within 36 h.After 36 h,MDA content increases significantly,the content of chlorophyll gradually decreases.The content of L-Glutathione Reduced(GSH) and the activities of... |
