| 摘 要： | 目的]为了解决仁用杏易遭受晚霜危害,选育出抗晚霜能力强的新品种。方法]以4株抗晚霜能力强的仁用杏优株初花期花枝为试验材料,经人工霜箱低温处理后取其花瓣、雄蕊、雌蕊,测定了过冷却点、电解质渗出率、超氧化物歧化酶（SOD）和过氧化物酶（POD）活性、可溶性蛋白含量。结果]优异种质36号的抗寒能力最优。不同品种间的抗寒性存在明显差异。花器官抗寒能力顺序为花瓣〉雄蕊〉雌蕊。结论]该研究为新品种的选育工作提供了理论依据。

| Abstract: | Objective] The experiment in the susceptibility of kernel apricot to frost hazard was conducted in order to breed new variety with anti-frost ability. Method] The branches in early flowering of 4 excellent kernel apricot germplasm being taken as the experimental material,the super-cooling point,the relative electrolyte leakage rate,the activity of SOD and POD,the content of soluble protein in the petal,stamen and pistil after the artificial low-temperature treatment in growth chamber were determined.
