摘　　要：仁用杏是以杏仁为主要产品的杏属果树的统称,在北方普遍栽植,耐干旱、抗性强且易于管理,对于改善生态环境、防止水土流失和荒漠化均有良好效果,是理想的经济型树种。但在实际生产中,仁用杏常遭受冬季严寒和早春晚霜的危害,产量受到影响,造成仁用杏的产业化发展受到制约。仁用杏的抗寒研究主要集中于新品种选育和生理生化机制方面:‘围选1号'等抗寒新品种已应用于抗逆研究及生产中;通过抗逆相关。物质的分析也使抗寒机制研究趋于深入。综合论述了仁用杏在分子生物方面的研究及其同科植物的抗寒性等,为仁用杏的进一步抗寒研究做参考和理论依据。Kernel apricot is a general designation of apricot producing almond. It has the advantages of being tolerant to drought, strong resistance and easy to manage, which are generally suitable to be planted in northern China. Kernel apricot has good effects on improving ecological environment, preventing soil ero- sion and desertification,making it an ideal non-timber tree species. However,in the actual production,ker- nel apricot often suffers from coldness in winter and frost in early spring, resulting in the reduction of the yield and limited development of industrialization. In this paper,the general situations and progress of cold resistance on kernel apricot study were summarized from three aspects： new variety breeding, physiological and biochemical mechanism and molecular biology. It would provide a reference and theoretical basis for further study on cold resistance of kernel apricot.
