Abstract
This study was conducted to investigate the effect of nonwoven fabrics weight(Ounce) on growth, quality and yield of oriental melon (Cucumis melo L. var. makwa Mak.). Seedling of 'Gumssaragi-Eunchun' was grafted on 'Shinthozoa' root stock. In this study, The minimum air temperature in 6 ounce at night was $4.8^{\circ}C,\;6.9^{\circ}C$ in 9 ounce, $7.9^{\circ}C$ in 12 ounce and $8.0^{\circ}C$ in 15 ounce, respectively. Leaf length, stem diameter, leaf numbers, leaf area, fresh weight and dry weight for 30 days after planting were better in high minimum air temperature at night than in low minimum air temperature, particularly leaf areas of the plant in 9 ounce was $370cm^2$ at 30 days after planting, $116\%$ in 12 ounce, $129\%$ in 15 ounce. The xylem exudates amount in 9 ounce for 24 hours just after basal stem abscission was 10.1mg. It was 1.2 times much in 12 ounce and 1.9times much in 15 ounce than in 9 ounce at 30 days after planting. The blooming of female was faster by 6 days in 15 and 12 ounce but was delayed by 3 days in 6 ounce than 9 ounce, and the days of blooming to harvesting were shorter by 3 days in 15 ounce and 4 days in 12 ounce but was delayed by 3 days in 6 ounce than in 9 ounce. Fruit weight, fruit length, fruit diameter, flesh thickness, soluble solids, and total yield was the highest in 15 ounce followed by 12 ounce,9 ounce and 6 ounce. Fermented fruit rate was the highest in 6 ounce followed by 9 ounce, 12 ounce and 15 ounce, and marketable fruit rates were 15, 12, 9 and 6 ounce in order. Compared to 1,781kg yield per 10a of 9 ounce, $19\%\;and\;49\%$ was increased under 12 ounce and 15 ounce but $47\%$ were decreased 6 ounce.
참외 무가온 재배 시 보온부직포 무게별 참외의 생육, 품질 및 수량에 미치는 영향을 검토하기 위하여 신토좌 대목에 금싸라기은천을 접목하여 정식 전부터 6온스, 12온스, 15온스 처리구와 대조구인 9온스를 4월 20일까지 덮어서 재배한 결과는 다음과 같다. 보온력이 높을수록 터널내 야간 기온이 높았는데, 6온스 $4.8^{\circ}C$, 9온스 $6.0^{\circ}C$, 12온스 $7.9^{\circ}C$ 그리고 15온스는 $8.0^{\circ}C$로 12온스와 15온스간에는 큰 차이는 없었다. 보온력이 높을수록 초장, 경경, 엽수, 엽면적, 생체중 및 건물중 등 정식 30일 후의 초기생육이 빨랐는데 특히 엽면적은 대조구인 9온스의 $370cm^2$ 비하여 12온스에서는 $116\%$, 15온스에서는 $129\%$였다. 정식 30일 후 일비액량은 9온스의 10.1mg에 비하여 12온스는 1.2배, 15온스는 1.9배 많았다. 9온스에서는 정식 47일 후 암꽃이 개화되었으나 15온스 및 12온스에서는 6일 빨랐으나 6온스에서는 3일 늦었고 첫 수확은 12 및 15온스에서 각각 3일, 4일 단축되었으나 6온스에서는 3일 늦었다. 평균과중, 과장, 과폭, 과육두께 및 당도는 15온스에서 가장 좋았고 12온스, 9온스, 6온스의 순이었다. 10a당 총수량은 15온스에서 가장 많았고 12온스, 9온스, 6온스의 순이었고, 발효과는 6온스에서 가장 많았고 9온스, 12온스, 15온스의 순이었고, 상품과 율은 15온스에서 가장 많았고 12온스, 9온스, 6온스의 순이었다.
