Fruit weight was significantly increased by 33 g or 79 g through half-tree of three out of four flower cluster thinning,consequently fruit calcium concentration was decreased by 1.62 or 2.66 mg/100g fresh weight respectively,it means that fruit calcium concentration was significantly affected by the treatments that significantly altered fruit size.

苹果树疏除花序1/2或3/4的数量使苹果平均单果重比不疏花分别显著增加了33 g或79 g，而果实钙浓度每百克鲜重分别降低了1.62 mg或2.66 mg，充分说明当疏花显著地影响果实大小时，果实内钙浓度也会明显地发生相应的变化。
