摘　　要：选用绿豆品种白绿9号(BL9)、白绿11号(BL11)、大鹦哥绿935(BL935)、大鹦哥绿985(BL985)为试材,在苗期、花期、成熟期测定绿豆不同抗旱性品种叶片脱落酸(abscisic acid,ABA)的含量,研究3个生长发育时期,绿豆不同抗旱性品种叶片ABA含量的变化情况,并初步分析ABA的动态分布与绿豆抗旱性的关系。试验结果证明,从苗期、开花期到成熟期,各品种叶片内ABA含量的动态变化呈逐渐升高的趋势,并且抗旱性较强的绿豆品种叶片ABA含量相对较低。特别是抗旱性不同的绿豆品种在开花期的叶片ABA含量差异达到极显著水平。In this study,changes of ABA content in leaves of four species of the mung bean（BL9,BL11,BL935,BL985） in seedling,blossom and maturation were determined by the ELISA method.The relationship between dynamic distribution of ABA and resistance to drought was analyzed.The results showed that ABA content of leaves of all mung bean varieties increased gradually from seedling,blossom to maturation.ABA content in mung bean leaves was lower in the drought-resistant varieties.The differences of ABA content in mung bean leaves at blossom were significant among varieties with different resistance to drought.
