摘要:
采用10%聚乙二醇6000(PEG6000)模拟干旱胁迫,研究内源一氧化氮(NO)在水杨酸调控新单29幼苗根系抗旱性中的作用。结果表明:与对照相比,干旱胁迫显著提高了玉米幼苗根系NO、脯氨酸、可溶性糖、可溶性蛋白、丙二醛(MDA)、过氧化氢(H2O2)含量及根冠比,显著降低了地上生物量;与单独干旱胁迫处理相比,水杨酸显著提高了玉米幼苗根系NO、脯氨酸、可溶性糖、可溶性蛋白含量及根系生物量、根冠比,显著降低了MDA、H2O2含量;NO清除剂则可以显著降低干旱和水杨酸诱导的NO的产生与脯氨酸、可溶性糖、可溶性蛋白含量,同时显著降低地上生物量、根系生物量及根冠比,并使MDA、H2O2含量显著升高,从而逆转干旱和水杨酸的上述效应。由上述结果可知,NO参与水杨酸对玉米幼苗根系抗旱性的调控。
