In the present paper, there are described the behavior of carbohydates and nitrogen compounds both in the basal and the apical parts of sweet potato slips of the variety "Okinawa No. 100" during their rooting period, The experimantal results obtained may be summarized as follows: 1. At the time of planting, the nitrogen compounds were abundant in the apical parts and little in the basaal parts of the slip, while the carbohydrates showed a reverse gradient though it was not so evident as in the case of nitrogen compounds. 2. At the pre-rooting period, translocation of nitrogen compounds and of carbohydrates to the basal parts were recognized. 3. After the rooting had once begun, more striking accumulation of nitrogen compounds and carbohydrates in the basal parts took place, while in the apical parts both nitrogen compounds and carbohydrates increased only slightly as compared with those at the pre-rooting period.
