水稻穗发芽与种子休眠研究现状

Research Status of Pre-harvest Sprouting and Seed Dormancy of Rice

水稻穗发芽与种子休眠是日常生产中的大难题,穗发芽后的水稻不仅产量明显降低,而且水稻的品质、储藏及来年播种都受到很大程度上的影响;种子休眠不利于水稻采收后立即种植,且无法对其进行发芽检测等。本文对水稻穗发芽与种子休眠的生理机制和控制措施进行归纳叙述,旨在为科研和生产实践提供理论支持。

The pre-harvest sprouting and seed dormancy of rice is a big problem in daily production. It leads to the yield decrease significantly,and the quality,storage and seeding in next year are heavily influenced;the dormant seed can not be planted immediately after harvest,and the sprouting rate can not be tested. This article summarizes the physiological mechanism and control measures of the pre-harvesting sprouting and dormancy of rice seed, so as to provide theoretical basis for research and productive practice of rice.
