摘　　要：研究了表油菜素内酯对绿豆下胚轴切段皮层细胞超微结构的影响 .结果表明 ,用表油菜素内酯处理下胚轴切段能够维持其细胞超微结构的完整性而延缓衰老过程 ,而对照下胚轴切段皮层细胞中的细胞器 (如核、线粒体和内质网 )在下胚轴离体 5 d后即解体消失 .The effects of epibrassinolide on ultrastructure of epidermous cell in hypocotyl segments of mung bean seedlings were studied. Hypocotyl segments treated with epibrassinolide(1 mg/L)maintained the integrity of ultrastructure of cell, and retarded the senescence, whereas the various organelles of the controls deteriorated after 5 days in vitro. The relationship between the effect of epibrassinolide in maintaining the integrity of ultrastructure of cell and retarding senescence was discussed.
