| 摘 要： | 采用水培和盆栽试验法，测定了不同磷水平下正常供水、交替变换水及持续干旱胁迫下玉米叶片中ＲＷＣ、ＭＤＡ含量、ＳＯＤ和ＰＯＤ活性。结果表明，干旱胁迫将导致叶片ＲＷＣ降低，ＭＤＡ含量升高，使细胞膜伤害加剧。ＳＯＤ和ＰＯＤ具有减缓ＭＤＡ积累的作用。干旱胁迫下，磷能有效地维持较高的叶片ＲＷＣ，增加其ＳＯＤ和ＰＯＤ活性，减少ＭＤＡ积累，提高生物学产量。采用多变水处理能显著降低干旱对作物的伤害

| Abstract: | Under different water and phosphorous conditions,the contents of RWC, MDA and activities of SOD and POD of maize leaves were determined during two kinds of incubation.The results showed that water stress could lead to RWC decrease,MDA content increase and cell membrance damage of leaves.The SOD and POD could decrease the MDA accumulation.Phosphorous could not only keep a higher RWC and lower MDA efficiently in maize leaves,but also could increase the SOD and POD activities and biological yield.At the same time,highly varied water treatment could as well remarkably decrease maize hurt under water stress. |
