摘  要：
以套袋和不套袋栖霞大香水梨为试材,采用固相微萃取(SPME)和气相色谱-质谱联用(GCMS)技术,研究了不同结果部位对梨果实香气的影响。结果表明,不同结果部位果实香气物质种类和含量存在显著差异,套袋树外围东部果实香气物质种类最多,为35种,含量最高,为4 076.01 ng/g,外围北侧香气物质种类最少,为24种,内膛下部果实香气物质含量最低,为421.22 ng/g。不套袋树外围南面的果实香气物质种类最多,为42种,含量最高,为10 001.14 ng/g,外围北面果实的香气物质种类最少、含量最低,分别为24种和357.08 ng/g。

摘  要：
With bagged and unbagged Qixia Daxiangshui pear as materials,the effect of different fruit setting positions on fruit aroma was studied using solid-phase microextraction(SPME)and gas chromatography-mass spectrometry( GC-MS) technologies. There were significant differences in the kinds and contents of fruit aroma components between the fruits set in different positions. Under bagged treatment,the most kinds of aroma components(35 kinds)were detected in fruits in the eastern periphery of the tree,and the content as volatiles was the highest as 4 076. 01 ng /g. The least kinds of aroma components appeared in the northern periphery of bagged trees,which was 24. The content of volatiles in fruits setting in inner and bottom of the tree was the lowest as 421. 22 ng /g. Under unbagged treatment,42 kinds of aroma components,which was the most,were detected in fruits setting in the southern peripheral of the tree,and the content of volatiles was the highest as 10 001. 14 ng /g. The fruits setting in the northern peripheral of unbagged trees had the least kinds and contents of volatiles,which were 24 and 357. 08 ng /g respectively.
