| 摘 要： | 采用人工水分胁迫处理,通过植物生理学方法,对10个常用玉米自交系进行了抗旱性研究。结果表明,不同玉米自交系存在明显差异,沈136、齐319、丹598和沈137耐旱性较好,可以作为玉米耐旱育种的基础材料。干旱胁迫下,玉米植株叶片相对含水量、丙二醛含量、电导率和ASI与玉米子粒产量极显著相关,能够比较准确地评价玉米自交系抗旱性的强弱,和抗旱系数、抗旱指数一样可以作为玉米育种耐旱自交系筛选的鉴定指标。

| Abstract: | According to plant physiologic methods,the drought resistance of ten ordinary maize inbred lines were studied at artificial water stress.The results showed that different maize inbred lines had significant different droceght resistance.The drought resistance of Shen 136,Qi 319,Dan 598 and Shen 137 were better than the other maize inbred lines and could be the fundamental genetic resource to enhance drought tolerance of maize.The relative water content,MDA content,electric conductivity and anthesis-silking i... |
