The contents of zeatin , gibberellin, indo-acetic acid and abscisic acid in the superior grains and the inferior grains were determined to analyze their relationship with grains-filling .

于抽穗后每隔6天取其强势粒和弱势粒，测定其玉米素、赤霉素、吲哚乙酸和脱落酸含量，分析其与籽粒灌浆的关系。

In stress conditions,abscisic acid（ABA） modulates stomatal apertures through an intricate signalling network to reduce water loss and this is crucial to improve plant tolerance.

在逆境胁迫下,脱落酸（ABA）通过一个复杂的信号转导网络来调节气孔的开度、减少水分的散失是植物获得抗逆性的重要机理之一。
