| 摘 要： | 大豆开花结荚期，不同发育阶段的幼蕾与花荚的脱落率不同，其中以花后５ｄ内的幼荚脱落最严重。与败育花荚相比，正常花荚中的干物质积累量均较高。细胞分裂素（ＤＨＺＲｓ，ＺＲｓ，ｉＰＡ）含量也较高，花后３～５ｄ的幼荚中表现更明显。脱落酸（ＡＢＡ）则是以败育幼蕾及花后３～５ｄ的幼荚中含量较高。不同发育阶段的大豆生殖器官中，正常开放花中的玉米赤霉烯酮（ＺＥＮ）含量最高

| Abstract: | The abscisic rate varied in flower buds, flowers and immature pods of soybean. The abscission was the most serious in immature pods of 5 days age among flower buds, flowers and pods. Compared with the normal reproductive organs, the aborted flower bud, flower and pod had lower contents of cytokinins. The differences were significant in pods of 5 days age. The content of abscisic acid in aborted pods of 5 days age was much higher than the nomal ones. The zearalenone content was the highest in normal opened flowers. It seems that different plant hormones are involved in the regulation of the abortion processes in soybean. |
