摘要:
为探索川西北高原乡土植物老芒麦的耐旱性,以野生老芒麦为研究对象,采用盆栽控水法模拟干旱胁迫环境,分析了苗期老芒麦在干旱胁迫下的形态和生理指标的变化特点,为其抗旱性育种提供了重要的理论基础,并对利用其有效防治川西北高原高寒草地退化、沙化等生态灾害具有重要的现实意义。结果表明,随着干旱胁迫天数的增加,野生老芒麦株高、叶面积和地上部分生物量积累增长减缓,根系干重和相对电导率不断上升,相对存活率、叶绿素含量持续下降。干旱胁迫已对苗期老芒麦产生了不同程度的伤害,抑制了生长,并降低了存活率。干旱条件下,为汲取更多水分,老芒麦将更多的生物量分配到根部,同时,降低生长高度和叶面积,以促进水分有效运输和防止水分过度蒸发。经耐旱隶属度分析,供试的8份野生老芒麦材料耐旱性强弱顺序为:14-001>14-165>14-235>14-065>14-251>14-115>14-189>14-021。
