The cuttings and apical portion of stein in sweet potato were growlh under artificial light and specific photoperied and temperature. Though the plant growth was poor under insufficient light intensity of artificial light, the tuber formations were induced at long light period (16L+8D) and not induced at short light period (8L+16D) and low temperature of darkparied. The determinative factor for tuber formation of sweet potato seems to be a stimulation which has intimate relationship with specific photoperiod and temperature and no direct relation with the growth of plant body and light intensity. The root pattern of inductive state for tubers and non-inductive state were different distinctly, the former were silky and slender, the latter were branchy, and stout appearence. This different root pattern must be due also to the specific photoperiod and temperature and may have any relationship with the stimulation for tuber formation from the point of auxin physiology etc. |
