Abstract

Recently, the interest and consumption of mini watermelon (Citrullus lunatus Thunb.) are increasing due to nuclear family and one person household. However, there’s no research for mini watermelon. Therefore, the purpose of the study is to develop standard cultivation method of mini watermelon. The test cultivar is ‘Minimi’, which is a small-sized fruit, the rootstock is ‘Bullojangsaeng’, which is a cucurbit line. Grafted plants were transplanted on April 5, 2017, and harvested in early July. Cultivated types were 3 methods, which are ∩-form, arched, and runner type, and plant spacing were 40, 60, and 80 cm, respectively. The rowth and yield in ∩-form was higher than that of the arched and runner types, and the sugar content was higher a bit. The yield per unit area was about 50% higher than ∩-form, which can be plant density cultivation than that of the runner type. The number of seeds per fruit of ‘Minimi’ was similar to that of ‘Sambokggul’, but seed weight was one third lower than that of ‘Sambokggul’. The content of lycopene was 30% higher than that of ‘Sambokggul’ watermelon, and the main sugar content is similar to or slightly less. In conclusion, the ∩-form staking cultivation was superior to the runner type or arched cultivation in terms of fruit setting ratio, yield and quality.

최근 1인 가족 증가 및 핵가족화로 인해 미니수박에 대한 소비가 증가되고 있다. 따라서 미니수박에 대한 표 준재배법을 확립하기 위하여, 재배유형에 따른 재식거리 가 미니수박의 생육, 수량성, 과실특성과 라이코펜 및 당 함량 등에 미치는 영향을 조사하였다. 정식 30일 및 90 일후 생육은 재배유형별로 재식거리가 클수록 생육이 양 호하였으며, 수확기의 후기생육은 포복형 재배보다는 아 치형이나 ∩자형에서 가장 양호하였다. 주당 착과수는 재 배유형별로 유의한 차이는 없었으나, 단위면적당 수량은 밀식재배가 가능한 ∩자형이 아치형과 포복형에 비해 50% 이상 높았으며, 당도가 다소 증가하였다. ‘Minimi’의 과실당 종자수는 대과종인 ‘삼복꿀’과 비슷하였으나, 종 자 100립중은 ‘삼복꿀’의 1/3크기로 작았다. 라이코펜 함 량은 ‘삼복꿀’보다 ‘Minimi’에서 30% 이상 높았고, 당성 분은 유의한 차이가 없었다. 따라서 미니수박의 재배방식 은 ∩자형 지주재배가 포복재배나 아치형에 비해 단위면 적당 수량과 품질이 높았으며, 재식거리는 120×40cm에서 수광량, 생육, 수량 및 품질 등에서 가장 양호하였다.
