Abstract

During the hydroponic culture of muskmelon, the effect of adding NaCl in nutrient solution and supplying CaCl_2 on the leaves of muskmelon on respiration and the changes in fruit quality during storage was evaluated. The rate of respiration was higher in fruit with NaCl treatment, but lower with CaCl_2 treatment than in control. The rate of respiration was much lower in fruit stored at low temperature, 5$\circ$C, than at room temperature, about 26$\circ$C. Same trends were obtained in the production of ethylene at low and room temperatures. The pulp firmness was lower in NaCl treated fruits, while higher in CaCl_2 treated fruits. Muskmelon fruits from control without CaCl_2 application were stored about five days at room temperature, whereas fruits treated with CaCl_2 can be stored about 20 days at low temperature. Soluble solid and total sugar contents in muskmelon fruit were higher in the both NaCl and CaCl_2 treatment than in control. The contents in fruits from NaCl treatment decreased during storage. The concentration of ethanol was much higher in NaCl treated fruits, but treatment with NaCl produced low amount of ethanol. NaCl treatment can produce high concentration of sugars in muskmelon fruits, but the shelf-life was decreased in the fruit. The storage problem can be avoided by the leaf application of CaCl_2.

양액재배기간중 NaCl 첨가재배와 CaCl2 엽면시비가 머스크멜론 과실의 저장중 호흡특성과 품질변화에 미치는 연구결과는 다음과 같다. 호흡량은 무처리 보다는 NaCl 처리구에서 증가하였고, 무처리 보다는 CaCl2 처리구에서 감소하였다. 저장은 실온(약 26°C)보다는 5°C저장에서 호흡량이 현저하게 낮았다. 에틸렌 발생량에서도 호흡량 변화와 유사한 경향을 보였다. 과실경도는 저장기간 동안 NaCl 무처리 보다는 처리구에서 낮았지만, CaCl2 엽면시비구에서 다소 높게 나타났다. 저장성은 무처리구의 실온저장에서 약 5일 정도였지만, CaCl2 처리구의 5°C 저장에서는 약 20일 정도 저장이 가능하였다. 가용성고형물 및 총당함량은 NaCl 및 CaCl2 처리가 무처리 보다는 높았고, 저장기간 동안 CaCl2 처리구에서 점차 감소하였다. 에탄올 함량은 NaCl 처리구에서 현저하게 많았지만, CaCl2 처리구에서 적은 경향을 나타냈다. NaCl 처리에 의해 고당도 과실생산은 가능하며, 저장성이 감소되는 것은 CaCl2 엽면시비에 의해 어느 정도 극복할 수 있었다.
