Methyl jasmonate （MeJA） solution with a volume fraction of 0.25% was sprayed on fruits of Vaccinium corymbosum ‘Gulfcoast’ during green fruit period. The types and contents of volatile components of ripe fruits were detected by using headspace-solid phase microextraction combined with gas chromatography-mass spectrometry technology. The results show that 36 volatile components are identified from fruits of the treatment group with a total content of 187.27 μg·kg^-1， and the types and total contents of volatile components of the treatment group are higher than those of the control group （without spraying MeJA）. The total contents of aldehydes and ketones are significantly （P<0.05） different between the treatment group and the control group， while the total contents of esters， alcohols， and terpenes are not significantly different between these two groups. In the treatment group， the contents of components including 2-hexenal， （E，Z）-2，6-nonadienal， trans-2-nonanal， 6-methyl-5-hepten-2-one， （E）-6，10-dimethyl-5，9-undecadien-2-one， and 1-octene-3-ol， etc. are obviously higher than those in the control group， and components including octanal， 2-nonanone， acetic acid， hexyl ester， α-pinene， and β-ocimene， etc. are present. It is suggested that spraying MeJA before harvest can improve the flavor quality of V. corymbosum ‘Gulfcoast’ fruits and enrich fruit aroma level.
