摘　　要：In order to investigate the effect of bagging on aroma components of ＇Qi xia daxiangshui＇ pear fruit, an experiment was performed, and the ingredients and contents of aroma volatile compounds of bagged and non-bagged fruit of ＇Qi xia daxiangshui＇ pear were studied by using heads space solid-phase microextraction （HS-SPME） and gas chromatography-mass spectrometry （GC-MS）. The results showed that： there were significant differences in the aroma varieties and contents of bagging and non-bagged fruit. In bagging treatment, 34 different varieties of volatiles were detected in ＇Qi xia daxiangshui＇ pear fruit; the total contents of aro- ma volatiles were 2 671.53 ng/g, while 42 ingredients of volatiles were detected in the non-bagged fruit; the total contents of aroma volatiles were 10 040.14 rig/g. Bagging significantly reduced the varieties and the contents of aroma volatiles in ＇Qi xia daxiangshui＇ pear fruit.为了明确套袋对‘栖霞大香水’梨果实香气的影响,以套双层袋‘栖霞大香水’梨为试材,不套袋果实为对照,采用固相微萃取(SPME)和气相色谱-质谱联用(GC-MS)技术,测定了‘栖霞大香水’梨果实香气组成和含量。结果表明:套袋‘栖霞大香水’梨和对照不套袋果实香气物质种类和含量存在显著差异,套袋‘栖霞大香水’梨检测到3类34种芳香物质,香气物质总量为2671.53 ng/g;不套袋果实检测到3类42种芳香物质,香气物质总含量为10 040.14 ng/g。套袋导致‘栖霞大香水’梨果实香气种类和含量显著降低。
