| 摘 要： | 研究了水分亏缺胁迫过程中小麦幼苗ＳＯＤ活性与ＭＤＡ积累的动态变化规律。发现不同品种ＳＯＤ活性及ＭＤＡ积累的动态变化明显不同。用胁迫全过程ＳＯＤ活性的变异系数和ＭＤＡ积累的速率来评价品种抗旱性是一种简便、可靠的方法。研究结果表明：小麦幼苗水分持续胁迫过程中ＳＯＤ活性动态变化的变异系数越小，品种抗旱性越强；ＭＤＡ积累速率越高抗旱性越差。

| Abstract: | The reseach result be made known.In sustained water stressed wheat seeding,the smaller the variation coefficient of the SOD activity dynamic state change,the better the breed drough resistance.The higher the MDA rete of accumulate,the weaker the breed drough resistance. |
