摘　　要：抽穗期是水稻的重要性状,决定水稻品种的地区与季节适应性.光周期与温度是水稻生育期调节的重要条件,多年来,对水稻感光性研究已有很多,但是机理并不清楚.由于生物技术的发展,近年来,关于水稻抽穗期的光周期调控机制研究增多并取得了一系列成果.对这方面的研究进行归纳,可为进一步明晰光周期影响水稻抽穗期的分子调控途径与机制提供参考与帮助.Heading day is a key trait for geographical and seasonal adaptation of rice.Photoperiod and temperature regulates rice grow and development.There were many studies on the photosensitivity of rice for several years,but the photoperiodic response controlling mechanism was still not clear.As the development of biotechnology in recent years,research on the mechanism increased and a series of achievements were obtained.It could be useful to further clarify the mechanisms that photoperiodic response controlling heading in rice by summarizing those research.
