Abstract

This experiment were conducted to investigate the response of growth and yield of potato after transplanting of plug seedlings 'Superior' and 'Dejima' produced at different plug cell size (105, 162, and 288) and photoperiod (8/16, 12/12, and 16/8, day/night) for 20 days in controlled plant growth system. Growth and relative growth rate of plug seedling 'Superior' was affected by plug cell size and photoperiod at 7weeks after transplanting. Tuber weight of 'Superior' was increased as cell size and photoperiod increased. That of 'Dejima' was highest in 105 cell and different with photoperiod. At 90 days after transplanting, tuber weight ($258.9{\sim}471.9\;g/plant) of 'Superior' was high in 105 and 162 cell size and 16/8 hr photoperiod. That ($278.2{\sim}428.0\;g/plant$) of 'Dejima' was high in 105 cell size, but was not different with photoperiod. The number of tuber per plant was $2.6{\sim}6.9$ of 'Superior' and $2.2{\sim}3.6$ 'Dejima'. Tuber number per plant was not significantly different with cell size and photoperiod. The large tuber over 80 g was $32.0{\sim}50.9%$ of 'Superior' and $41.0{\sim}56.7%$ of 'Dejima'. The large tuber in 'Superior' and 'Dejima' lowered as the cell size decreased. The large tuber of 'Superior' increased as photoperiod increased, but that of 'Dejima' was not differed. As the results, the optimal plug cell size and photoperiod of potato seedling is considered to be below 162 cell and over 12 hr of photoperiod.

환경이 조절되는 폐쇄형 식물생장시스템에서 플러그 셀 크기(105공, 162공, 288공)와 일장(8/16, 12/12, 16/8hr, 낮/밤) 처리를 각각 달리하여 20일간 생산된 감자 플러그 묘 '수미'와 대지'의 생육과 수량에 미치는 영향을 알아보고자 실험을 수행하였다. 정식 7주째 '수미'의 플러그 셀 크기와 일장처리는 생육과 상대생장률에 차이를 주었다. '수미'의 주당 괴경 중은 셀 크기와 일장이 증가함에 따라 증가하였다. '대지'의 괴경 중은 105공 셀 크기에서 높았으며, 일장 처리에 차이를 보였다. 90일 재배 후, '수미'의 괴경 중($258.9{\sim}471.9g$/주)은 105공, 162공 처리와 16/8 hr 일장 처리에서 괴경 중이 높았다. '대지'의 괴경중 ($278.2{\sim}428.0g$/주)은 105공 처리에서 높았으나 일장처리 간에는 차이가 없었다. 주당 괴경 수는 '수미'가 $2.9{\sim}6.9개, '대지' $2.2{\sim}3.6개로 플러그 셀 크기와 일장 처리에 따른 유의성은 없었다. 80g 이상의 괴경 크기 비율이 '수미'는 $32{\sim}50.9%, '대지'는 $41.0{\sim}56.7%로, 두 품종 모두 288공 셀 크기에서는 감소하였고, 일장 처리 간에는 품종에 따른 차이를 보여 '수미'는 일장이 증가함에 따라 괴경 수가 증가하는 경향을 보였으나, '대지'는 일장 처리에 따른 차이를 보이지 않았다. 이상의 결과, 초기 묘 소질이 감자 생육 및 괴경 중에 영향을 줌으로써 플러그 묘를 이용한 감자 생산에 적합한 플러그 셀 크기는 162공 이하, 12시간 이상의 일장이 필요하리라 판단되었다.
