The following are the results obtained in the experiment appling several treatments to the pieces of 40g to 50g of the sweet potato, CHUNG-SEUNG #100, in order to prevent them from rotting and to speed their germination in growing the sweet potato for the feed-stuff by the direct planting method.
1. Planting the seed pieces of sweet potato with nontreatment resulted in rotting them and losing the stalks considerably.
2. The treatment of Gibberelin 25ppm aqueous solution didn't have any effecton germination.
3. The treatment of Fermate and Uspulun were effective for preventing the seed pieces from rotting, but it was recognized that they delayed germinations and the first stage growth a little.
4. The curing treatment speeded the formation of wound healing tissue and prevented the seed pieces from rotting, and germination was speeded and the days from planting to germination were shortened during the treatment But the surface of the seed pieces was changed white, dry. and solid. And germination growth after planting was not steady, on the contrary, a tendency to be delayed was found in it.
