| 摘 要： | 植物激素脱落酸(ABA)对植物的生长发育具有多方面的调节作用,比如种子休眠、萌发,营养生长,环境胁迫反应等。大量研究显示,ABA也参与了植物的成花调控。影响植物成花调控的环境因子,包括光周期变化、春化作用、干旱等均会导致植物体内ABA代谢的变化。本文从调控植物开花的4条主要途径与植物体内ABA代谢变化之间的相互关系,花芽分化时期ABA在植物叶芽和花芽中的动态分布以及离体培养条件下ABA对花芽分化的影响等方面总结了ABA与植物花发育这一领域的最新研究进展。对ABA在植物成花诱导和花发育中的作用进行了综合分析。

| Abstract: | As a phytohormone, abscisic acid (ABA) regulates many aspects of plant growth and development, such as seed dormancy, germination , vegetative growth, and environment stresses. Evidence show that ABA involves in the control of flowering. The environmental factors involved in flowering induction, such as photoperiod changes, vernalization, and drought, affect ABA levels. Summarized here are the recent progresses on understanding the correlation between the four major pathways of flower induction and the ABA changes, on the ABA distribution in leaf buds and flower buds during bud differentiation, and on the ABA effect on bud differentiation during the tissue culture. The role of ABA in flower induction and development is discussed. |
