| 摘 要： | 本文研究了外源多胺(精胺、亚精胺、腐胺)与玉米耐旱性的关系。结果表明，外源多胺处理降低了水分胁迫下玉米叶片细胞膜透性增加的程度和膜脂过氧化程应，并延缓了玉米叶片叶绿素和可溶性蛋白质含量的下降．这些结果说明外源多胺在减轻或抵御自由基伤害，在增强玉米耐旱性上具有相当明显的效果．研究还表明，在增强玉米的耐旱性上，三种多胺的效果依次为精胺(四胺)、亚精胺(三胺)、腐胺(二胺)．

| Abstract: | Three kinds of polyamines, namely spermine,spermidine and putrescine 2HCl,were used to study the relationship between the exogenously applied polyaminesand the drought tolerance of maize.The experimental results showed that pretreatment with the polyamines decreased the level of membrane lipid peroxidation of cell and thepermability of plasma membrane and retarded the decrease of chlorophyll and solubleprotein contents of leaf, cell in maize under water stress. On the effect of increasingdrought tolerance of maize, above three kinds of polyamines was spermine, spermidineand putrescine-2HCl,respctively. |
