                 MT 表示机械修剪疏果,CK 表示对照,不疏果。MT 和 CK 间的差异显著性用“*”(P<0.05)、“* *”(P<0.01)和“* * *”(P<0.001)表示,
               下同。A:果实横径;B:果实纵径;C:2 个处理不同时期果实大小;D:单果质量;E:果实硬度。MT stands for mechanical pruning-mediated
               fruit thinning,CK stands for control group. The difference between mechanical pruning-mediated fruit thinning and CK was makerd by“*”(P<
               0.05)、“* *”(P<0.05)and“* * *”(P<0.001),The same as below.A:Transverse diameter of fruit;B:Longitudinal diameter of fruit;
               C:The Pokan fruits sampled at different developmental stagest;D:Single fruit weight;E:Fruit firmness.
