Abstract

This study was conducted to investigate the effect of functional cover film on oriental melon fruit quality under unheated plastic greenhouse cultivation in cold period. The 6 kind of films having different characteristics were covered at plastic greenhouses and oriental melon seedlings were cultivated at 2 regions of Seongju, respectively. The air-temperatures in plastic greenhouses of J-1 and J-2, having high infrared absorption rate, were about $2{\sim}5^{\circ}C$ higher than K-3. The contents of ${\beta}-carotene$ and sugar of fruit showed significant difference between functional and normal films. The sucrose, determining a sweetness during maturation, and soluble solids content of fruits cultivated in J-1, J-2, J-3, and K-1 were higher than those of K-2 and K-3. Ascorbic acid of fruits was highest in K-2 having low light transmission rate and thermo-keeping capacity. There was no significant difference in mineral content among all of cover films. These results indicated that the use of functional greenhouse covering films could improve fruit quality such as ${\beta}-carotene$ and sugar content of oriental melon.

참외의 저온기 무가온 시설재배에서 원적외선 흡수율이나 무적성 등의 물리적 특성을 향상시킨 필름 피복이 참외 과실품질에 미치는 영향을 조사하기 위하여 과실 성분을 조사하였다. 일반 PE필름과 기능성이 추가된 5가지의 필름을 5동의 하우스에 피복하여 성주지역 2곳에 각각 설치한 후 재배하였다. 하우스 내부 온도는 높은 적외선 흡수를 보였던 필름인 J-1과 J-2에서 K-3에 비해 약 $2{\sim}5^{\circ}C$정도 높았다. 과실의 ${\beta}-carotene$ 함량과 당함량은 기능성 필름과 일반필름에서 유의성 있는 차이를 보여 J-1, J-2, J-3 및 K-1에서 높게 나타났는데 이것은 필름의 특성에 따른 보온효과 때문인 것으로 생각된다. 성숙 후 단맛을 좌우하는 sucrose 함량도 기능성 필름에서 높았는데 이로 인해 당도도 향상되는 결과를 보였다. Ascorbic acid 함량은 투광량과 보온성이 낮은 K-2에서 더 높은 경향을 보였고 무기원소 함량은 처리간에 차이가 없었다. 이상의 결과는 참외의 저온기 단동 하우스재배에서 보온성과 투광성을 향상시킨 필름을 피복함으로써 참외 과실의 품질을 일부 개선할 수 있음을 시사하였다.
