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.
