　　以生产上主栽的杏扁品种龙王帽、一窝蜂、优一和国仁以及优株07-3（一窝蜂抗寒优株）为试材，2010年对自然低温冻害胁迫后杏扁花器官（花瓣、雄蕊、雌蕊）的冻害情况进行了调查；2011年对各品种（优株）盛花期的1a生花枝进行室内模拟低温冻害试验，调查花器官的冻害发生率，并测定了不同品种（优株）雌蕊的可溶性蛋白和丙二醛含量，分析参试材料的抗寒性。结果表明：优株07-3抗寒性最好，一窝蜂次之，龙王帽、优一和国仁抗寒性较差；花器官的抗寒性顺序为花瓣＞雄蕊＞雌蕊。

Apricot flat varieties Longwangmao, Yiwofeng, Youyi, Guoren and Germplasm 07-3 ( Yiwofeng cold hardiness germplasm ) were selected as test material, freezing conditions of apricot flat floral organ ( petal, stamen, pistil) were investigated after natural low temperature stress in 2010.The indoor experiment of simulation low temperature freezing on one year spray of cultivars ( strains) were tested in 2011, the freezing rate of floral organs was investigated, the contents of soluble protein and MDA of pistil were determinated, and the cold hardiness of cultivars ( strains) were analyzed.The results showed that the cold hardiness of Germplasm 07-3 was best, the second was Yiwofeng, and the cold hardiness of Longwangmao, Youyi and Guoren were weaker.The order of cold hardiness of floral organs was petal>stamen>pistil.
