Abstract
'Hongro' and 'Gamhong' apples grown at the Gochang-si in the southern part of Korea were harvested on September in 2002 for storage study. Each cultivar was divided into two groups of maturity based on the harvested date. Immature fruits were harvested 10 days early compared to fruits having proper maturity. This study was conducted to evaluate quality the change of 'Hongro' and 'Gamhong' apples newly bred by different storage methods with PE film package and CA conditions. A typical climacteric respiration pattern was observed in new variety 'Hongro' and 'Gamhong' apples stored at room temperature. The results indicated that fresh quality of the stored fruits in CA condition was better than that in other treatments during storage. Qualities of apples were least changed at CA storage of 3% $CO_2$ and 1% $O_2$. CA storage was effective in maintaining the freshness of 'Hongro' and 'Gamhong' for 16 weeks.
