水稻分蘖形成的生理特性及其基因调控

Physiological Characteristics and Gene Regulatory of Rice Tiller Formation

水稻分蘖的发生和合理利用对改善水稻产量起着极其重要的作用,而其遗传基础对水稻分蘖的发生及有效分蘖的形成起主导作用,并且这种作用受环境条件的制约。本文从水稻分蘖的形成规律和水稻分蘖形成的环境调控角度概述了水稻分蘖形成的生理特性,揭示了水稻分蘖发生的基因调控及重要功能,为水稻生产和育种合理利用分蘖特性提供参考。

The tillering ability in rice,to some extent,is closely related with rice yield.Genetic elements of rice tiller play leading roles in its occurrence and forming which are subjected to the surroundings.In this article,the physiological characteristics of rice tiller are investigated through its forming system and the environment effect,meanwhile,gene regulating and significant function which influence the rice tiller forming are presented,it provides a reference in application of the tiller physiology characteristics in rice production and breeding.
