Abstract

This study was conducted to evaluate the effects of the fog-cooling system on the growth and yield characteristics of two large-fruited paprika cultivars during summer cultivation season. The temperature inside the greenhouse equipped with fog-cooling system was 2-3°C lower than that in the control. The results of study show the possibilities of maintaining indoor temperatures below 35°C and relative humidity at the level of 80% using fogcooling system during hot seasons of the year. Plant height, fruit weight and number of fruits per plant were higher for both cultivars in the fog-cooling treatment compared to those in control. Mean fruit weight and yield per unit area were higher in the fog-cooling treatment than those in the control. However there were no significant differences in sugar content, flesh thickness and locule number of fruits due to fog-cooling system. Number of fruits with epidermal cracking was decreased in the fog-cooling system for both paprika cultivars. Mineral contents of plants such as nitrogen (N), potassium (K), calcium (Ca), magnesium (Mg), were not affected due to fog-cooling treatment.

여름철에 파프리카 코이어 배지경에서 ‘Cupra’, ‘Piesta’ 2품종을 공시하여 시설 내 포그냉방 효과에 의한 파프리 카 생육을 검토코자 하였다. 시설 내 포그 냉방처리를 통 해 무처리보다 온실 내의 온도가 2~3°C 낮았으며 최고온 도를 35°C이하로, 그리고 실내습도도 80% 내외로 유지할 수가 있었다. 초장, 엽수 등 생육은 포그냉방 처리구가 무 처리에 비해 양호하였다. 평균과중은 두 품종 모두 포그 냉방 처리구에서 158~160g으로 무처리보다 무거웠고, 주 당 착과수는 ‘Cupra’, ‘Piesta’ 모두 포그냉방 처리구가 각 각 18.4, 18.3개로 무처리에 비해 7~8개 많았다. 상품수량 은 ‘Cupra’, ‘Piesta’ 두 품종 모두 포그냉방 처리구가 각 각 6,027, 5,890kg/10a으로 무처리에 비해 유의적으로 많 았다. 과실의 당도는 처리간에 차이가 없었으며 ‘Cupra’, ‘Piesta’ 두 품종 모두 5~6°Bx 였으며 과육의 두께는 포그 냉방 처리 효과가 없었다. 과실의 열과 발생률은 포그냉 방 처리구가 낮았으며 품종 간에는 차이가 없었다.

이상의 결과에서 여름철 파프리카 수경재배시 포그냉 방으로 시설내 온도의 강하와 습도조절이 가능하였으며 그에 따른 결과, 생육이 양호하며 과실의 품질 또한 좋 아짐을 알 수 있었다.
