摘　　要：以不同产地的"红地球"葡萄为试材,通过常规生物学指标测试以及穿刺和TPA法质构测试,比较了2012年和2013年3个产地的"红地球"葡萄果实基础生物学特性、质地品质的差异性,长期贮藏效果以及其相关性。结果表明:3个产地的果实由于气候因素以及采收期等的不同,导致采后果实品质差异性显著,最终造成贮藏品质的差异性明显。综合2年数据比较来看,张家口果实采后基本品质最高,蓟县果实品质中等,抚宁果实最差,造成入贮后贮藏效果差异明显;60d时,腐烂率张家口果实<蓟县果实<抚宁果实,掉粒率张家口果实<蓟县果实<抚宁果实,但贮藏90d时,蓟县果实和抚宁果实腐烂率和掉粒率都很高。另外,果实采后维生素C含量、可滴定酸含量、可溶性固形物含量与果实贮藏期腐烂率、掉粒率呈显著负相关。综合认为,张家口果实由于其采收时品质最好,导致贮藏效果最好,而抚宁果实采收时品质最差,最终贮藏效果也最差。可见,葡萄果实采收后的入贮品质将对贮藏期效果产生较大的影响。Taking ‘Red Globe’grapes from different origins as materials,the routine biological indicators through puncture test and TPA texture test were conducted,the basic biological characteristics,the differences of texture quality,long-term storage effects and their relevance of the three area‘Red Globe’grape fruits in 2012 and 2013were compared.The results showed that the three area postharvest fruits quality were different obviously.Consolidated the two-year-old data comparisons,Zhangjiakou’s fruit had the highest basic highest quality,the second was Jixian’s,Funing’s was the worst,resulting in the significantly difference in the storage.In the 60 days,the decay rate was Zhangjiakou〈Jixian〈Funing,the falling particle rate was Zhangjiakou〈Jixian〈Funing.But when in the 90 days,the decay rate and falling particle rate of Jixian and Funing’s fruits were both very high.In addition,the postharvest fruit vitamin C content,content of titratable acid,soluble solids content were significantly negative correlated with decay rate,falling particle rate in storage.The conclusion was that fruits’ s storage effect of Zhangjiakou’s was the best because the quality of fruits was good when harvest,fruits’ s storage effect of Funing was the worst because the quality of fruits was bad,it showed that the storage quality of grape fruit would have an great impact on storage effect.
