Abstract:: The volatile components in 10 varieties fruits of half high-bush blueberry and low-bush blueberry were analyzed by static headspace and gas chromatography-mass spectrometry to provide reference for breeding fine aroma blueberry.The results showed,total 5 kinds volatile components were detected include 2 kind alcohols，6 kind esters，8 kind hydrocarbons，5 kind aldehydes,8 kind ketones.Among them,the content of esters was the higest,the content of acetic acid,octyl ester,Butanoic acid,3-methyl-,ethyl ester,Pentanoic acid,ethyl ester were higher.and the aroma quality of the blueberry varieties with esters as the main volatile component was more significant.The volatile components of different blueberry groups had significant difference.The low-bush blueberry detected a total of 27 kinds of volatile components,their contents and types were higher than those of halfhigh-bush blueberry.There were also significant differences among different blueberry cultivars.‘Emil’ was the highest,with 27 volatile components detected,with a total content of 4 519.44 ng·g-1,and ‘Fundy’ detected was the least,which total content was 628.03 ng·g-1.
