Abstract: The concentration of ethanol and acetaldehyde in MeiGuiXiang (fragrant rose scent) grape after 120 days storagewas studied .It showed that CO2 injury of grape happened in 10%O2+18%CO2 after 100 days storage, 10%O2+15%CO2after 120 days storage, while low O2 injury during storage was not apparent. Low O2 and high CO2 caused the obviousincrease of ethanol and acetaldehyde in grape during storage. Acetaldehyde was the main factor causing the gas injury ofgrape.

Key words: table grape, storage, gas injury, ethanol, acetaldehyde
