Abstract:

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 are influenced by factors like environment, plant itself, plant shape, structure, endogenous pytohormones, polyamines, mineral elementsand growth regulate chemicals etc. The regulating mechanism of bud differentiation of anthophyta is alse discussed.
