Methods such as Northern blotting, physiological and biochemical analysis were used to examine the genie expression of HSP70 and AC, the content of exohormone(IAA,ABA), and the change of legume abscission rate. The main results were shown as follows.

• 通过Northern分子杂交和生理生化分析测定等方法，检测处理后不同大豆品种植株花英离层区细胞HSP70和AC基因表达量、内源激素(ABA、IAA)含量以及花荚脱落率等各项指标的变化，研究这些指标之间的相互变化规律，其主要结果概述如下：
