Taking ‘520’ pear and ‘Wanxiang’ pear as materials，the effect of different storage methods on the fruit firmness and PPO activity of them were studied.The results showed that compared with the control，the flesh soften speed and outsourcing bags of fresh pear fruit was relatively slow at low temperature；at different temperatures，to outsourcing bags and with no bags，the lower the temperature was，the lower the PPO enzyme activity in fruit softening was，followed with the slower speed；different storage temperatures had a certain effect on the hardness of the pear fruit and PPO activity changes，the combination treatment of low temperature with fresh bags could keep better fruit firmness.
