摘　　要：对现有杏品种资源进行抗寒性评价与筛选,建立杏树抗寒性评价技术体系,选育晚花、抗冻品种对华北地区杏树生产具有重要意义.在对鸡蛋杏、意大利2号等7个品种花期冻害情况进行全面调查的基础上,以这些品种花器官为试验材料,研究了杏树抗寒生理,评价杏品种的抗寒性并建立杏抗寒性评价技术体系,为进一步的抗寒育种奠定基础.Apricot varieties of existing resources are evaluated and screened to establish cold resistance evaluation of apricot trees.Breeding late-blooming and cold-resistant species are of great significance for production of apricot trees in north China.On the basis of a comprehensive sunvey of seven varieties of apricot trees about the freeze injury during blooming period,the flower organs of these variesses are used to study the cold-resistant physiology,evaluare their cold resistance and establish cold resistance evaluation system.
