Abstract

Apple(Malus domestica Borkh cv.Fuji)fruit was used as material to study the effect of daubing with 0.5%Ca(NO3)2on Ca concentration and antioxidative capacity of apple fruit peel.The young fruit were daubed with 0.5%Ca(NO3)2 on 30 days after full blossom.The result showed bagging could reduce the Ca concentration of apple peel,MDA content and the SOD、POD activities of bagged apple peel were lower than the control treatment.After removing bag,MDA content and the SOD、POD activities of bagged apple peel were higher than the control treatment.After the treatment of calcium,the Ca concentration of apple fruit peel increased,the SOD、POD activities increased,MDA content reduced.These enhanced the capacity of scavenging superoxide radical,inhibited membrane peroxidation,reduced the damage of environmental stress after removing bag.
