摘要
水稻是我国最重要的粮食作物之一,寒地水稻因具有良好的口感而受到广大消费者的喜爱,冷害是对寒地水稻生产最重要的危害之一。我国北方稻区芽期、苗期和孕穗期遭遇低温环境常导致发芽率低、幼苗生根少、叶片枯黄和结实率降低。培育寒地水稻是使寒地水稻抵御寒冷地区低温环境的一种有效的解决方法。从水稻芽期、苗期和孕穗期的耐冷性鉴定、耐冷性基因定位2个方面综述耐冷研究的相关进展,为寒地水稻育种奠定理论基础。
Rice is one of the most important food crops in China.Because of its good taste,rice in cold regions is loved by consumers.Chilling injury is one of the most important hazards to rice production in cold regions.The low temperature environment encountered in the bud,seedling and booting stages of rice areas in northern China often results in low germination rate,less rooting of seedlings,yellow leaves and reduced seed setting rate.Cultivating rice in cold regions is an effective solution to make rice in cold regions resist the low temperature environment in cold regions.This article summarized the related progress of cold tolerance research from two aspects:the identification of cold tolerance at the bud stage,seedling stage and booting stage,and cold tolerance gene mapping,laying a theoretical foundation for rice breeding in cold regions.
