抄録

A tuber of sweetpotato plants (Ipomoea batatas Lain. cv. Koganesengan) was grown in the air space of a hydroponic system, where relative humidity around the tuber was controlled at 50, 70 or 90% RH under an air temperature of 28°C. Diurnal variation of the tuber volume was measured on-line by using a laser micrometer system, and effect of the ambient humidity on the tuber growth was analyzed. In all of the humidity conditions, the larger increase in the tuber volume was found during the nighttime. The nighttime growth rate was clearly affected by the humidity around the tuber, which became higher in the order of 90, 50 and 70% RH.
