摘要
文章第一部分简单说明了种子休眠的主要类型及其危害性,并以此为基础强调合理调控水稻种子休眠状态的必要性;第二部分从种皮障碍、环境因素、植物激素的调节这三方面入手,分析了水稻种子休眠的机理;第三部分结合安徽荃银高科种业股份有限公司的工作经验与研究结果,着重阐述了水稻种子休眠调控的现行技术手段,包括种植管理、种子处理等水稻种子休眠的物理调控技术以及抗穗发芽药剂的投放、破休眠药剂的投放等化学调控技术,并对水稻超干种子耐热性的利用、基因编辑技术的利用这些新技术手段进行了说明。
The first part of the article briefly explains the main types and dangers of seed dormancy, On this basis, the necessity of reasonably regulating the dormancy state of rice seeds;The second part starts from the three aspects of seed skin disorder,environmental factors and the regulation of phytohormones, The mechanism of rice seed dormancy was analyzed;The third part combines the working experience and research results of Anhui Quanyin High-tech Seed Industry Co., Ltd, The current technique of the regulation of rice seed dormancy is emphasized, Physical control techniques of rice seed dormancy, such as planting management and seed treatment, as well as chemical control technologies such as anti-ear germination agents and anti-dormancy agents, The utilization of the rice and the utilization of the gene editing technology are described.
