Abstract

This study was conducted to find proper material of brushing stimulation for height suppression of tomato plug seedlings. The tomato seeds were sown in 40-cell plug tray filled with commercial seedling medium and brushing stimulation was started at 18 days after sowing. Acrylic, polypropylene film, and weaving film were used by materials of brushing stimulation and, non-treatment and diniconazole treatment were used as the control. In acrylic treatment, the plant height was the shortest and the stem diameter was the thickest. Leaf growth was the lowest in diniconazole treatment. However, the SPAD value was the greatest in diniconazole treatment. The dwarf rate was the greatest in acrylic treatment. In acrylic treatment, the T/R ratio was the lowest and compactness was the greatest. In conclusion, use of the acrylic as material for brushing stimulation has higher dwarf rate than diniconazole treatment, and has advantages height suppression and seedling quality.

본 연구는 토마토 공정묘 생산 시 생장 억제를 위한 적정 brushing 소재를 구명하기 위해 수행하였다. 토마토 종자를 상업적 공정육묘용 상토가 충진된 40구 플러그 트레이에 파종하였으며, 파종 후 18일째부터 brushing 자극을 처리하였다. Brushing 소재는 연질 아크릴, 폴리프로필렌, 직조필름 소재를 이용하여 brushing 처리를 하였으며, 대조구로 무처리구와 diniconazole을 엽면살포 처리하였다. 연질 아크릴 처리에서 초장이 유의적으로 가장 짧았고, 경경은 가장 두꺼웠다. 잎의 크기는 diniconazole 처리에서 가장 낮았으나, SPAD값은 가장 높게 나타났다. 연질 아크릴 처리에서 T/R율이 가장 낮고, 왜화율과 충실도가 가장 높게 나타났다. 결과적으로, brushing 자극 처리를 위해 연질 아크릴 소재를 이용하는 것이 diniconazole 처리 보다 왜화율이 높아 도장 억제에 유리하며 묘 소질이 우수한 묘를 생산하는데 적절할 것으로 판단된다.
