At 15-day intervals from October 8th in 1996, we transferred Idesia polycarpa seedlings gathered from Okinawa and Mie Prefectures into three growth-chambers regulated at 10, 15 or 25°C under 24hours day length, and investigated sprouting processes of terminal buds. Concerning the treatments of 15 and 25 t, on February 10th and 25th we also transferred Okinawa and Mie seedlings into these chambers. Further, in addition to these temperature treatments, we transferred Okinawa plants into 10 and 15°C chambers on March 12th. There were the periods that terminal buds were difficult to sprout under 25°C. For the terminal buds of Okinawa and Mie seedlings, it seemed that the minimum temperature to sprout buds dropped to at least 10°C under the condition of 10°C, while under 15 and 25°C it scarcely dropped. Among 10°C treatments, however, the days required to sprout seemed to be different, which were shorter in the treatments from January 23th on as compared with those until mid-December. It shows that the minimum temperature to sprout droppped greater in the outdoor than under the condition at lot.
