摘　　要：以红富士苹果为试材,探讨采前喷施Ca(NO3)2、CaCl2、糖醇螯合钙和柠檬酸钙等对红富士苹果果实品质和贮藏性能的影响。结果表明:各种喷钙处理比对照喷清水可更好地保持贮藏期间果实的硬度、可溶性固形物含量及Vc含量。贮藏60d时,采前喷钙处理的果实硬度、可溶性固形物含量、SOD酶活性和POD酶活性高于对照,而果实丙二醛含量、PG和Cx活性则低于对照;贮藏120d时,Ca(NO3)2、CaCl2及糖醇螯合钙处理的果实硬度和可溶性固形物含量均显著高于对照。Effects on quality and storage properties of Red Fuji apple fruits were investigated by preharvest spra- ying calcium nitrate, calcium chloride, calcium chelate or calcium citrate. The results showed that the properties of hardness, soluble solid content and ascorbic acid in preharvest calcium fruits were higher than those of control at the same storage period. Compared with spraying water, preharvest calcium applications increased fruit hardness, soluble solid content, activities of superoxide dismutase （ SOD ） and peroxidase （ POD ） while malondialdehyde （ MDA ） content, polygalacturonase （ PG ） activity and cellulose （ Cx ） activity in fruits were lower than those of control after storage for 60 days. Preharvest spraying with calcium nitrate, calcium chloride and calcium chelate significantly in- creased fruit hardness and soluble solid content after storage for 120 days. In short, calcium sprays could improve the storage properties of Red Fuji apple fruits.
