摘要
综合近半个世纪的研究结果表明，玉米抗旱性是玉米在水分胁迫环境下，体内细胞在结构、生理及生物化学上发生一系列适应性改变后，最终在植株形态和产量上的集中表现。因而在干旱条件下，根冠比、植株高度、叶片大小、叶着生姿态，叶片及叶片的蜡、角质层厚度，雄穗大小和ＡＳＩ等形态特征；叶水势、细胞的渗透调节能力，细胞内ＳＯＤ、ＰＯＤ、ＣＡＴ、ＬＯＸ、ＰＥＰｃａｓｅ和硝酸还原酶活性以及Ｖ一Ｃ、ＧＳＨ和Ｐｒｏ的变化，均可作为玉米抗旱性鉴定的指标。
The research results for more than half a century showed that maizedrought resistance is a concentrated reflection in plant morphology and yields with itsbody cells undergoing a series of adaptable changes in structure,physiolo一physiologyand biochemistry under stress conditions,Therefore, the change of root/canopy progor-tion ,plant height, leaf size ,leaf angle,the thichness of leaf and it's wax or cuticle,tassel size and ASI(anthesis一silking interval )and so on shape character;the ψw ofleaf , permeate adjust ability of cell ,the active of SOD,POD ,CAT,LOX,PEPcaseand nitrate ,reductase,and the content of V一c ,GSH and free Pro in the cellunderdrought condition ,can be reganded the index of drought resistance identification of maize.
