摘　　要：【研究目的】研究不同产地红地球葡萄品质指标及发病率的变化,明确影响红地球葡萄贮藏效果的主要因素。【研究方法】以5个不同产地红地球葡萄为试验材料,测定冷藏条件下果实的带菌率、果梗含水量、发病率、可溶性固形物、可滴定酸及多酚含量的变化。【研究结果】不同产地红地球葡萄的贮藏特性不同,其中怀来葡萄的带菌率与发病率均较低,果梗含水量低且下降缓慢(下降率为5.60%),可溶性固形物含量和多酚含量高,比其他产地葡萄有更好的抗病性。各指标与果粒发病率相关程度不同,贮藏过程中可溶性固形物含量及果肉多酚含量变化与发病率的相关系数均大于0.828;采收时红地球葡萄果肉多酚含量与贮藏80d后果粒发病率相关系数为0.885。【结论】贮藏过程中可溶性固形物含量及果肉多酚含量变化可以较好的监测葡萄发病率的变化,采收时红地球葡萄果肉多酚含量能够作为大批量红地球葡萄贮藏效果的预测因子。[OBJECTIVE]Study on the varieties of main quality indexes and disease incidence rate of different regions＇ red globe grape during cold storage, to determine the predictive indicator for storage effect of red globe grape. [METHOD]Red globe grape from five product regions as material, the disease incidence rate, the carrier ratc, tile water content of peduncle, the content of titratable acid and the phenolic substance content were measured during cold storage. [RESULTS]The results showed that the red globe grape from Huailai had the lower carrier rate and disease incidence rate, the lower and stable of the water content of peduncle （descent rate is 5.60%）, higher SSC and phenolic substance content, disease resistance is better than orthers; The relativity to tile disease incidence rate is not at the same level in dlferent quality indexes, the correlation coefficient between the SSC and the phenolic substance content and the disease incidence during the cold storage are above 0.828; the correlation coefficient between the initial phenolic substance content of flesh and the disease incidence rate after 80d＇ storage is 0.885. [CONCLUSION]The SSC and phenolic substance content can well monitor the disease incidence rate; the phenolic substance content could be a reliable indicator to predict the batch quality of red globe grape.
