Abstract
The purpose of this study is to determine the effects of sugar solution supply to cut-sprouts of sweet potato on rooting and growth. Rooting was promoted by sugar solution supply. It was cleared that affects of sugar solution promoting rooting was not due to osmotic potential of sugar solution. The affects of sucrose solution was higher than that of glucose. It was suggested that effects of sugar solution supplied to cut-sprouts was not only to promote rooting but also to enhance the growth of cut-sprouts and the formation or thickening of tuberous root after supplying sugar solution.
