摘要：

温度和光照是影响小麦发育的主要因素，不但决定了小麦生态型的区域分布，也通过调控小麦的发育阶段、器官建成、穗分化起始及进程等因素而影响小麦的产量。本文介绍了低温春化和光周期对小麦发育特性影响的分子基础，对其调控机制及互作模式研究进展进行了综述。

Abstract:

Temperature and photoperiod are main influencing factors on development of wheat. Vernalization and photoperiodic response not only determin ecological distribution of wheat, but also influence yield through regulating the developping stage, organ building, inflorescence initiation and proceeding. This paper review the molecular mechanisms and interaction model for the effect of low temperature and photoperiod on growth habit of whaet.
