초록

본 실험은 기존의 플러그 육묘 시스템과 원통형 종이 포트 시스템을 상호비교하여 주요 과채류 육묘의 생육 특성을 검토 하기 위해 수행되었다. 초장, 엽면적, 경경, 생체중 등의 지상부 생육은 토마토, 오이, 수박 모두 원통형 종이포트와 플러그 트레이 간의 차이가 없었다. 총 근장은 토마토와 오이는 육묘초기, 수박은 전 기간동안 플러그 트레이가 원통형 종이포트에 비해 길었다. 뿌리의 직경별로 각 뿌리의 길이를 구분한 결과, 토마토는 시험구간 차이가 없었지만 오이와 수박은 모든 굵기의 뿌리에서 플러그가 종이포트에 비해 20~251% 길었다. 토마토 뿌리의 생체중은 육묘기는 플러그 트레이가 원통형 종이포트에 약 30% 무거웠지만 생육이 진전될수록 차이가 감소하였고, 정식 이후는 시험구간 차이가 없어졌다. 오이 뿌리의 생체중은 육묘기부터 정식 이후까지 플러그묘가 약 20~30% 무거웠고, 정식 이후 까지도 생육이 진전될수록 차이가 커지는 경향을 보였다. 수박은 육묘기부터 정식 7일후까지는 원통형 종이포트 묘의 지상부 생체중 및 건물중이 무거웠지만, 정식 7일 이후부터 역전되었다. 결론적으로 원통형 종이포트 묘와 플러그 트레이 묘의 지상부 생육은 전반적으로 차이가 없었고, 지하부 생육은 플러그묘의 생육량이 많았다.

This study was conducted to examine the growth characteristics of seedlings of several major fruit vegetables and compare them between plants grown with the conventional plug seedling system (Plug) and those grown with the cylindrical paper pot system (CPP). There were no significant differences in shoot growth characteristics, such as plant height, leaf area, dry weight, and fresh weight, between tomato, cucumber, and watermelon plants grown with the CPP and Plug systems. The total root lengths of tomato and cucumber plants grown with Plug were longer than those grown with CPP at the beginning of seedling growth, and the total root lengths of watermelon grown with Plug were longer than those grown with CPP throughout the whole seedling period. The length of root that separated five steps according to the diameter of the root of tomato did not differ between CPP and Plug, but those of cucumber and watermelon were 20-251% longer with Plug than with CPP for all kinds of roots. The fresh weight of Plug-grown tomato roots was about 30% heavier than that of CPP-grown tomato during the seedling period, but the difference decreased as growth progressed. Finally, there was no difference between plants before and after transplanting. The fresh weights of the Plug-grown plants were about 20-30% heavier than those of CPP-grown ones in terms of the whole seedling. After transplanting to the Wagner pot, the shoot growth of Plug-grown watermelon plants in terms of dry weight was low until 7 days had passed. However, this tendency was reversed from 8 days after transplantation onward. In conclusion, there were no significance differences in the growth of shoots between plants grown with the CPP and Plug systems. However, root development was better with Plug than with CPP.
