Pak-choi cv. 'Dai Tokyo' were sown in 72, 128 and 288-cell plug tray to study the cell sizes effects on seedling growth. Results indicated that, no significant difference on the fresh weigh, dry weight, leaf number, leaf area and root length among different cell sizes at early stages, However, the difference among treatments increased and became significant after 12 days of sowing. Seedlings in 72-cell plugs showed the best growth. The root/shoot ratios was found higher on seedlings in 288-cell plugs than those in 72-cell and 128 cells. The relative growth rates of roots and shoot were also found higher at early growth stage and decreased as seedling ages increased. Both the seedlings in 72 and 128-cell plug had the similar trends in plastchron index values, but that of the seedlings in 288-cell plugs was significantly lower.
