干旱胁迫及复水对豌豆叶片内源激素含量的影响
Effect of drought stress and water recovery on endogenous hormone content in leaves of pea
摘要
Abstract
Pot experiment was conducted to study the influence on the content of endogenous hormone including Ab-scisic acid (ABA), Indole-3 - acetic acid (IAA), Gibberellins (GA) and Zeatin (ZT) in the leaves of pea (Pisum Sativum Linn.) under drought stress and water recovery. The results indicated that light and serious drought stress in seedling stage increased the content of ABA by 1.03% and 1.10% respectively, and the content of IAA rose by 16.44% and 61.99% respectively. While they decreased the content of GA by 1.44% and 4.79% respectively, and the content of ZT declined by 2.10% and 3.16% respectively. Light and serious drought stress in early flowering stage increased the content of ABA by 1.60% and 1.90% respectively, and the content of IAA raised by 14.42% and 27.75% respectively. The content of GA decreased by 1.17% and 1.79% respectively, and the content of ZT declined by 16.65% and 19.83% respectively. light and serious drought stress in filling stage increased the content of ABA by 0.83% and 1.63% respectively, and the content of IAA raised by 12.25% and 29.02% respectively. The content of GA decreased by 0.87% and 1.76% respectively, and the content of ZT declined by 7.89% and 13.23% respectively . Meanwhile, drought stress impacted the proportion between endogenous hormones. Water recovery had compensation effect subjected to growing stage, degree and duration of stress and water recovery days to endogenous hormones . Water recovery also led to changes in endogenous hormones ratio.关键词
