사과 신육성 품종인 ‘홍로’와 ‘감홍’의 저장 특성을 조사하기 위하여 미숙과와 적숙과에 대한 알맞은 수확시기 설정과 적정 저장온도, 저장방법 등에 따라 과실의 품질 변화에 미치는 영향에 대하여 수행하였다. ‘홍로’와 ‘감홍’은 상온 저장 상태에서 climacteric 호흡 경향을 보여 주었다. CA 저장이 실험한 저장 방법 중 선도 유지에 가장 우수하다는 결과를 얻었다. 3% CO2와 1% O2의 CA 저장고에 보관한 사과가 가장 적은 품질변화를 나타냈다. ‘홍로’와 ‘감홍’의 신선도는 상온 저장에서 3주, PE 필름 저장은 12주, 그리고 CA 저장은 16주까지 각각 유지되었다.


The study was conducted to evaluate the change of qualities of newly bred cultivar ‘Hongro’ and ‘Gamhong’ apples by different storage methods with PE film package and CA conditions. ‘Hongro’ and ‘Gamhong’ apples grown at the Geochang-city in the southern part of Korea were harvested in September in 2002 for storage study. Each cultivar was divided into two groups of maturity based on the harvest date. Immature fruits were harvested on the early periods of 10 days compared to mature fruits with proper maturity. A typical climacteric respiration pattern was observed in new variety ‘Hongro’ and ‘Gamhong’ apples stored at room temperature. Fruit weight, ethylene production, firmness, and skin color were used as quality indicators for the stored apples. The results indicated that overall fresh qualities of the stored fruits in CA condition was better than apples in no package (control) and PE film package during storage. Quality of apples was changed little in CA storage of 3% CO2 and 1% O2. CA storage was effective in maintaining the freshness of ‘Hongro’ and ‘Gamhong’ for 16 weeks.
