| 摘 要： | 介绍了油菜素内酯促进植物生长、提高作物产量的作用，并简述了促进生长的生理代谢基础。通过比较油菜素内酯与生长素、赤霉素促进生长作用方式的异同，提出油菜素内酯促进生长的信号传导路径不同于其它植物激素。另外从细胞的形态发生、细胞壁扩展的机制和细胞骨架在细胞伸长中的作用等几个方面对油菜素内酯促进植物生长的细胞及分子生物学机制进行了详尽的论述。

| Abstract: | This review introduces the role of brassinolide in promoting plant growth and raising the yield of crops and recounts its physiological basis in brief. Comparing the difference in the modes of action between brassinolide and auxin, gibberellin, it has been proposed that the signal transduction pathway of BR is different from tho
se of other plant hormones. Moreover, the article discusses the mechanism by which promotes plant growth in detail by analysing the cell morpho genesis, expansion of cell wall and the cole of cytokeloton in cell elongation. |
