Abstract

In our study, oriental melon (Cucumis melo L. var makuwa Makino) was harvested in Seongju at major harvest time from June to August with the intervals of one month in 2009. In order to elucidate the effect of meteorological condition of harvest time on fruit quality and water-soluble vitamin contents of oriental melon, quality attributes including weight, hardness, and sugar were examined and water-soluble vitamin contents such as folic acid and vitamin C were analyzed. Fruit quality factors and water-soluble vitamin contents were the highest in June when rainfall was low and solar radiation was high. Meanwhile, both of them were the lowest in July when it was the worst weather condition for cultivation of oriental melon. After then, the contents of folic acid and vitamin C increased when the rainfall had decreased in Aug. The contents of both vitamins were much high in placenta than peel and flesh. In conclusion, the meteorological condition of the summer season by torrential rains and lack of solar radiation influence water-soluble vitamin contents, especially folic acid contents of oriental melon as well as quality attributes such as hardness and sugar.

경상북도, 성주 지역에서 2009년 6월에서 8월 사이 매달 참외를 수확하여 수확시기의 기상환경이 참외의 수용성 비타민 함량 및 품질에 미치는 영향을 평가하고자 하였다. 과실 품질평가를 조사하기 위하여 무게, 경도 그리고 당도 등의 특성을 조사하였고 수용성 비타민인 엽산과 비타민 C의 함량을 측정하였다. 수확시기에 따른 과실특성을 조사한 결과 강우량이 적고 일사량이 많은 6월에 수확한 과실이 무게, 경도 및 당도가 가장 높게 나타났고, 강우량이 많은 7월에 급격히 감소하는 경향을 보여주었다. 8월에 일사량이 증가하고 강우량이 감소하면서 다시 증가하는 것을 확인할 수 있었다. 참외의 대표적인 비타민인 엽산과 비타민 C의 함량을 측정한 결과, 6월에 수확한 참외에서 가장 높은 함량을 보여주었고, 7월에 현저히 감소하였다. 과실의 특성 조사 결과와 마찬가지로 엽산과 비타민 C의 함량은 강우량이 감소하는 8월에 다시 증가하는 경향을 보여주었다. 부위별로 분석해 본 결과 태좌 부위에 다량의 엽산과 비타민 C가 함유되어 있음을 알 수 있었다. 이상의 연구결과는 강우량 증가에 의한 수분장애 및 일사량 부족은 참외 과실의 품질뿐만 아니라 수용성 비타민 함량에도 영향을 미치고 있고, 특히 엽산 함량을 크게 감소시키는 것으로 나타났다.
