摘要
花时调控对水稻(Oryza sativa L.)生产具有积极意义。上午提早花时是避免水稻开花期遇高温引起颖花不育的有效措施之一,而不育系与恢复系的花时同步是水稻杂交制种获得高产的重要条件。总结了遗传因素、环境条件和植物激素对水稻花时的影响,探讨了花时调控的机制,提出了花时研究中今后应重点关注的问题。
The regulation of floret opening time is valuable to rice （Oryza sativa L.﹚ production. Floret opening in the early morning is an adaptative measure to avoid sterility caused by heat stress at anthesis in rice. Synchronization of floret opening time between cytoplasmic male sterile and restorer lines is essential for high-yield seed production of hybrid rice. The effects of endogenous genes, environmental factors and plant hormones on floret opening time were reviewed. The mechanisms of floret opening were discussed. Some key points of further research were proposed.
