방울토마토 잠액 수경재배에 육묘단계를 생략한 재배기술을 확립하기 위하여 ‘Pico’, ‘Pepe’ 및 ‘Koko’ 3품종의 측지를 육묘상에서 15일간 육묘한 것과 양액 재배상에 바로 정식하고 양액의 농도를 표준과 50% 농도의 2수준으로 처리하여 생육상태와 수량을 조사하였다. 1. 직접정식이 육묘정식보다 초기 생육단계에서 초장이 길었고, 엽수가 많았으며 엽면적이 넓었다. 수확시기는 직접정식이 육묘정식보다 6일 정도 빨랐고 품종간에는 ‘Pepe’가 다른 2품종보다 빨랐으며 양액 농도간에는 차이가 없었다. 2. 과일 1개당 평균 무게는 정식묘가 양액의 농도에 따른 영향은 없었고 품종간에는 ‘Pepe’가 적었다. 그리고 수량은 표준농도의 양액에 직접 정식한 ‘Pepe’에서 가장 많았다. 3. 과즙의 당도는 직접 정식한 구가 육묘 정식한 구보다 높았고 품종간에는 ‘Pepe’가 높았다.

The purpose of this research was to develop labor-saving cultural practices of cherry tomatoes in the deep flow technique (DFT) by omitting the process of raising seedling. Three cultivars, ‘Pepe’, ‘Pico’ and ‘Koko’ were propagated by the immediate setting of cuttings(lateral shoots) to the culture bed and by setting seedlings obtained by raising cuttings for 15 days, and grown in the standard and half - strength solution. 1. The immediate setting resulted in higher plants, larger number of leaves and larger leaf area during the early growth stage. And the harvest time was hastened by six days in the direct setting than that in the seedling setting. It was also earlier in ‘Pepe’, but not significant by different between two strengths of nutrient solution. 2. The average fruit weight was affected only by cultivars, but not by the type of cutting and the strength of nutrient solution. The highest yields were obtained from the immediate setting of ‘Pepe’ in other cultivars grown in the nutrient solution of standard strength. 3. Brix degree of treated cherry tomato juice was higher in ‘Pepe’ tomato cultured by immediate setting than others.
