Abstract
The experiments were conducted to investigate the effects of plug cell shape on growth of seedlings and development of root systems in cabbage after transplanting. A plug cell with a convex inner wall, a cell with a slit wall, and a normal cell were used for examination.
There was no remarkable difference in seedling growth due to cell shape, though the growth of seedlings in convex cells was slightly suppressed. There was no influence of cell shape on cabbage head weight. Convex cells and slit cells were found to suppress root circling. The roots of seedlings grown in convex cells extended deeply after transplanting and uprooting resistance of the plants increased. However, the roots of seedlings grown in slit and normal cells did not extend deeply after transplanting.
