摘　　要：以延边地区苹果梨树为试材,探索苹果梨树体生长期进行钙处理后对叶片钙调蛋白(CaM)含量及POD、PPO活性的影响。结果表明:钙处理对苹果梨叶片的CaM含量及POD、PPO活性有明显影响。其中幼果期、果实迅速膨大期、果实成熟期3个时期都喷施质量分数为0.5%CaCl2+20 mg/L NAA的处理对增加叶片CaM含量的效果最好,果实迅速膨大期喷施质量分数为0.5%CaCl2对降低叶片POD、PPO活性的效果最好。Apple-pear growing in Yanbian area were sprayed Ca^2＋ during growing stages, and then determine the CaM content and POD,PPO activity in the leaves. The results showed that calcium treatments affected CaM content and POD, PPO activity apparently. Among the treat- ments, the treatment of spraying 0.5% CaCl2＋20mg/L NAA at the three growing period obtained the best effect on increasing CaM content. While spraying 0. 5 % CaCl2 at fruit rapid enlargrement stage got the best effects on reducing the activities of POD and PPO.
