Abstract: Experiments were carried out with grape variety Meiguixiang.The results showed that when O2 and CO2 was controlled at 10%and 8%respectively,"Meiguixiang"grape had a best quality after 120 days storage at 0℃.This trestment could control the fungal disease,reduce berry decay and abscission, and keep the stem fresh and green.With ethanol content not increasing,dramatically.The optimal gas composition was 10%O2+8%CO2.CO2 injury happened in 10%O2+18CO2 after 100 days,10%O2+15CO2 after 120days,while low O2 injury wasn’t apparent.

Key words: Meiguixiang grape , Controlled atmosphere storage , Optimal value , Limit value
