摘要
花芽分化是有花植物发育中最为关键的阶段,同时也是一个复杂的形态建成过程。这一过程是在植物体内外因子的共同作用和相互协调下完成。了解植物花芽分化的机理对于制定合理的栽培措施、进行花期调控等具有重要意义。笔者就植物花芽分化过程中的形态结构、环境因素、植物体自身因素以及生长调节剂对花芽分化的影响做了简要的归纳,对植物花芽分化的调节机制作一概述,并对花芽分化过程中基因对成花的作用做了简要探讨。
Flower bud differentiation is the most critical stage of anthophyta, as well as a complicated morphogenesis process. This progress is undertaking with the interaction of internal and external factors. It will be of great importance to understand flower bud differentiation mechanism, therefore to adopt suitable planting measures, to control flowering time and realize genetic regulation. This article summarized the differentiation of flower bud process of anthophyta is influenced by factors like environment, plant itself, plant shape, structure, endogenous phytohormones, polyamines, mineral elementsand growth regulate chemicals etc. The regulating mechanism of bud differentiation of anthophyta was also discussed.
