以2年生红砂(Reamuria soongorica)幼苗为试材,采用盆栽试验研究了正常水分(CK)及轻度、中度和重度干旱胁迫下喷施0.1,1,10和100μmol·L^(-1) 4种浓度外源脱落酸(abscisic acid,ABA)对红砂幼苗生理特性的影响,分析了红砂抗旱性对外源ABA的响应。结果表明:干旱胁迫下外源ABA的喷施促进了红砂体内渗透调节物质脯氨酸、可溶性蛋白和可溶性糖的积累,能明显阻止干旱胁迫后红砂体内超氧化物歧化酶(superoxide dismutase,SOD)和过氧化物酶(peroxide enzyme,POD)活性的减弱以及叶绿素含量的降低,抑制受旱红砂叶片丙二醛(malondiadehyde,MDA)增生,从而增强红砂的抗旱性。但是外源ABA对红砂干旱胁迫下的生理调节作用有一定的浓度限制值即10μmol·L^(-1),超过此浓度,作用会减小。外施ABA对红砂抗旱生理机能产生影响并不表现在对某一种生理指标上,而是多个指标的相互关联和相互影响。综合分析表明,干旱胁迫下叶面喷施一定浓度的脱落酸可以维持红砂生长季叶片正常的生理代谢功能,有效控制叶片的衰老进程。
