Abstract

The summer production of sweet pepper in Korea which cultured in the highland area such as Hapchon is essential for a year-round export, but has the problem, fruits lose easily those marketability. This study was carried out to find changes of fruit quality in response to storage on sweet pepper cultivars in summer. Seven cultivars of sweet peppers, 'Jubilee', 'Plenty', 'Goal', 'Romeca', 'Derby', 'Midas' and 'Maximalia' were obtained iron growers in Hapchon which was highland of 600-800m from sea level and stored at $10^{\circ}C$ with box packing. Fruit quality was evaluated every 4days up to 4weeks. The weight loss of 'Jubilee' was the lowest, that of 'Romeca' was the highest. The firmness of 'Goal' was maintained highly for 4weeks and the red cultivars was higher than those of other color cultivars. The lightness of 'Jubilee' was sensitively affected by storage duration. Seeds of 'Plenty' and 'Derby' were plentifully browned after 4weeks storage. The occurrence of fruit rotting was after 16-204ay storage and those of 'Plenty' and 'Maximalia' were the earliest. The marketability of 'Jubilee' and 'Romeca' maintained by 70% for 16 days was the highest, but most cultivars lost those by 20% after 24days storage. It may be suggested that the marketability of sweet pepper producted in summer can be stored at $10^{\circ}C$ for 2weeks to maintain that of 80%.

착색단고추의 일본 수출시장 확대를 위해서는 단경기인 여름철에 고랭지 여름재배를 통한 연중공급이 매우 중요하게 여겨지고 있지만, 여름에 생산된 과실은 상품성이 쉽게 상실되는 문제점을 안고 있다. 따라서 본 연구에서는 여름에 생산된 착색단고추 7품종(빨간색 'Goal', 'Plenty', 'Jubilee', 노란색 'Derby', 'Romeca', 'Mydas' 및 오렌지색 'Maximalia' 등)의 저장에 따른 품질의 변화를 비교하였다. 시험에 사용된 과실들은 합천의 600-800m고랭지에서 생산된 것을 구입하여 수출용 박스에 포장하여 $10^{\circ}C$에서 저장하였고, 과실품질 조사는 4주간 4일 간격으로 하였다. 감모율은 'Jubilee'가 가장 낮았고 'Romeca'가 높았다. 경도는 'Goal'이 저장 4주 동안 높게 유지되었고, 색깔별로는 빨간색 품종들이 높은 경도를 보였다. 과색의 L value는 저장 기간이 길어질수록 감소하였는데, 'Jubilee'가 가장 민감하게 반응하였다. 종자의 갈변은 'Plenty'와 'Derby'가 가장 많았다. 과실의 부패는 16-20일부터 발생하였는데, 'Maximalia'와 'Plenty'가 빨리 시작되었다. 상품성은 'Jubilee'와 'Romeca'가 저장 16일째까지 70% 이상을 유지해 가장 높았지만, 저장 24일부터는 대부분의 품종에서 20%이하로 상품성을 거의 상실하였다. 따라서 여름에 생산된 착색단고추 과실들은 $10^{\circ}C$에서 저장할 경우, 2주정도 까지는 80%내외의 상품성을 유지할 수 있었다.
