Abstract: Delicious line apple fruit were stored at 0-1℃ for 120 days in CA,simple CA(SCA)and cool storage(CS)condition.The contents of aroma volatites by stored fruit was measured by gas chromatography during storage time. The results showed that:(1)In CS condition,the contents of acetaldehyde,ethanol and ethyl acetate in the flesh of Starking fruit increased gradually,reached their peaks at 60 days,then declined from 60 days to 120 days.However,in SCA condition,the mean contents of ethanol and ethyl acetate was lower than that of CS condition,but acetalsehyde content was obviously higher at 90 and 120 days.(2)The content of acetaldehyde in non spur type Starking fruit in SCA condition was lower than that of spur type Starkrimson,Redchief and Ultrared Del,but ethanol and ethyl acetate contents in Starking fruit was higher than that of spur type varieties at 90 days in storage.(3)Starking fruit in SCA condition had 13 kind volatatite aromo substances,including ketone,aldehyde,alcohol and easter.From 0 to 120 days in storage,alcohol and easter produced their peaks,ketone changed smoothly,but aldehyde increased contenously.Fruit soluble solid content did not significantly decreased at 90 days in SCA storage,meanwhile,the peak of total aroma volatites appeared,but the peak of CA treatment delayed to 120 days.
