摘要
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1 a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 cuhivars (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 cuhivars (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.
