摘  要：
[目的]研究套袋苹果果实中钙素分布及抗氧化酶活性与苦痘病的关系,为解决苹果栽培中钙的生理代谢障碍提供依据。[方法]以红富士苹果为试验材料,测定摘袋后和储藏期内果实不同部位Ca2+含量变化和抗氧化酶的活性。[结果]果实照光面Ca2+含量高于背光面,果实梗洼处Ca2+含量高于萼洼处;果实照光面SOD、POD、CAT、APX活性高于背光面,梗洼处SOD、POD、CAT、APX活性高于萼洼处;果实照光面MDA含量低于背光面,梗洼处MDA含量低于萼洼处。[结论]果实照光面苦痘病发病率低于背光面,果实梗洼处苦痘病发病率低于萼洼处。

摘  要：
[Objective]The aim was to study the distribution of Ca in bagged apple fruit and the relationship between antioxidant enzyme activity and bitter pit disease,which will provide a basis for resolving Ca metabolism disorder in apple cultivation.[Method]With Fuji Apple as the tested material,the changes of Ca2+ content and antioxidant enzyme activity in different parts of apple fruit after picking bags and storage period were determined.[Result]The results showed that Ca contents in the light surface of fruits were higher than that in the backlight surface.The Ca contents of stalk cavity were higher than that of calyx-end.The activities of SOD,POD,CAT and APX in the light surface of fruits were higher than that in the backlight surface.The activities of SOD,POD,CAT and APX of stalk cavity were higher than that of calyxend.The contents of MDA in the light surface of fruits were lower than that in the backlight surface.The contents of MDA of stalk cavity were lower than that of calyx-end.[Conclusion]The incidence rate of bitter pit in the light surface of fruits were lower than that in the backlight surface,and the incidence rate of bitter pit of stalk cavity were lower than that of calyx-end.
