摘要: 以新疆地方杏品种‘树上干’杏6个不同株系为材料,在0、–2、–4、–6、–8和–10 ℃低温处理后,测定了花蕾和盛开花的褐变率、半致死温度、游离脯氨酸与MDA含量以及SOD、POD、CAT酶活性共7项指标,从而筛选出耐寒株系S6,为‘树上干’杏生产和育种提供参考。

Abstract: To determine cold tolerance of the cultivars of‘Shushanggan’apricot,six genetypes of Xinjiang local apricot variety‘Shushanggan’were selected as trial population,seven indicators of flower organs including browning rate,LT50,free proline and MDA contents,SOD,POD and CAT activities were established and investigated under artificial freezing test(0,–2,–4,–6,–8,–10 ℃),the results showed that the cold resistant genetype is S6,which gave a theoretical support for the breeding and production of‘Shushanggan’apricot in Xinjiang.

Key words: apricot, Shushanggan apricot, cold hardiness
