摘　　要：以四个杏品种为试材,用方差分析和多重比较的方法,研究比较了休眠期不同杏品种枝条内SOD、POD酶活性变化与抗寒性的关系。结果表明:杏品种枝条内SOD、POD酶活性依次为沙金红>麻真核>华县大接杏>意大利Ⅱ;杏枝条中SOD、POD酶活性与它们的抗寒性呈正相关,即SOD、POD酶活性越高,抗寒性越强。With the methods of variance analysis and the multi-comparison,the author focuses on the relationship of enzyme activity of SOD and POD and their tolerance to cold by four different vavieties of almond in dormant period.The results are： SOD and POD＇s activities of branch of almond are listed as follows： Shajinhong〉Mazhenhe〉Huaxiandajiexing〉ItalyⅡ;SOD and POD＇s activities of branch of almond are positive related with their tolerance to cold,the higher of SOD and POD＇s activities,the stronger of almond＇s tolerance to cold.

关 键 词：休眠期 杏 SOD酶活性 POD酶活性
