摘要
低温冻害是小麦生产中经常遭受的自然灾害,是制约小麦产量和品质的重要环境因素之一。综述了小麦冻害类型、抗寒生理机制(细胞膜系统、渗透调节物质、抗氧化系统、光合特性和内源激素)和分子机制(抗寒基因、抗寒组学),并探讨了小麦抗寒研究存在的问题和解决办法,为开展小麦抗寒机制研究和抗寒育种提供重要参考。
The freeze injury is a frequent natural disaster in wheat production,which is one of the important environmental factors restricting wheat yield and quality. In this paper,the type of wheat freeze injury,the physiological mechanism(cell membrane system,osmotic adjustment substances,antioxidant system,photosynthetic characteristics and endogenous hormones)and molecular mechanisms(cold resistant genes,cold resistant omics) of wheat cold resistance were summarized. The problems and solutions in the study of wheat cold resistance were also discussed,which provided an important reference for the research of cold resistance mechanism and breeding of wheat.
