摘要
水稻是世界上的主要粮食作物之一,低温将导致水稻发育延缓,长期遭受低温胁迫易导致水稻枯萎死亡.全球每年约有1 500万hm2的水稻面临低温胁迫危害,低温冷害已成为水稻减产的主要原因之一.为系统了解水稻耐低温机理研究进展,总结了低温对水稻细胞结构特征的影响、低温对水稻生理生化特性的影响、水稻耐低温优良品种选育和水稻耐低温的分子机理的研究现状,并展望了水稻耐低温品种的未来选育方向.
Abstract
Rice is one of the world's most important food crops and has a very long history of cultivation in our country.Low temperature damage to rice is one of the major causes for the decline in rice production.According to statistics,about 15 million hm2 of rice is damaged by cold stress every year.Low temperature harm to rice has become a global natu-ral disaster.In order to systematically understand the research progress of low temperature tolerance mechanism of rice,this paper summarizes the effects of low temperature on the structural characteristics of rice cells,the effects of low tem-perature on the physiological and biochemical characteristics of rice,the breeding of excellent varieties of low tempera-ture tolerance of rice and the molecular mechanism of low temperature tolerance of rice,and look into the future breeding direction of low temperature tolerance varieties of rice.
