摘要

This paper gives the result of research made to find the influence of temperature on the translocation of foliar-applied P32 of sweet potatu in 1958. The absorption of P32 from one leaf of sweet potato increased progressively with succesively higher temperature when the plants were held in darkness over night (15hr) at soil temperatures of 10°, 20°, 30°, and 40°C, while the optimal air temperature for P32 absorption was 30°C when plants were held at 10°, 20°, 30°, and 40°C of air temperature. P32 was translocated mainly into the root and lower stem below the node of the P32 treated leaf. The effect of soil temperature on the P32 accumulation in root was generally stronger than that of air temperature, espesially the accumulation in root was greater at the soil temperature of 30° and 40°C which were higher than the temperature of leaves and stem. When roots of a plant were divided into two groups and each of halves was exposed to different temperature in darkness for 20 hours, the translocation and accumulation of P32 were better at 30°C than 40°C, better at 30°C than 20°C, and 20°C than 10°C root temperature.
