A rice seedling (3-5day old) from a seed with husk has a long seminal root and four or five short crown roots, on the other hand a seedling from a seed without husk has longer crown roots and a shorter seminal root. When rice seeds without husks were grown on agar gel suspended with powdered husks or supplemented with water extracts of rice husks, the elongation of seminal roots were observed. The promotion rates were dependent on the amounts of husks added or extracts supplemented. These facts suggest that husks have plant growth substance(s). Isolation of plant growth substance(s) was attempted to afford an active substance (0.5mg)
