摘　　要：以黄冠梨果实为试材,通过对常温贮藏条件下黄冠梨果实果心褐变发病率与褐心指数的统计分析,研究不同采收期对黄冠梨褐心病的控制效果以及对黄冠梨贮藏品质的影响,以期确定黄冠梨的最佳采收期。结果表明,黄冠梨褐心病的发生与果实成熟度密切相关,早采果实硬度显著高于晚采果实,且在贮藏过程中仍能完成后熟作用,可溶性固形物和可滴定酸含量升高,能够达到晚采果实的含量水平,晚采果实硬度下降快且褐心率高。黄景泰地区冠梨适宜采收期为8月15-30日。The control effects on browning heart and storage quality of Huangguan pears with different maturity are studied,which through the statistics of the brown heart rate and brown heart index analysis of Huangguan pear during storage at room temperature,in order to select the best harvest of pear. The result shows that occurrence of brown heart is closely related to the maturity of Huangguan pear,the firmness of early harvest fruit is significantly higher than late harvest fruit,and still complete afterripening during storage,the content of soluble solids and titratable acid are increased,to reach the levels of the late harvest fruit,and late harvest fruits have a fast decreased of firmness and higer brown heart rate. Therefore,Huangguan pear optimum harvesting period is August 15 th to August 30 th.
