The purpose of this study was to understand the changes of bud dormancy and carbohydrates content of shoot in subtropical area of Taiwan. Single bud of cuttings taking from Shin-shen, Shin-Hua and Pin-Tung area were tested respectively in 25℃ growth chamber during September 1983 to February 1984. The residual of cuttings were analyzed for the carbohydrates content. 1. In Shin-Sheh area: Most of the buds enter their dormancy in late September and keep the deepest from early November to late December. The buds began to burst from late December and have no dormancy in the begining of January. The starch content increased as the dormancy became deeper and total sugar content decreased on the contrary. 2. In Shin-Hua area: Two peaks of bud dormancy were found in late October to early November and mid December to early January. The bud began to burst in late November and in late January. There is no significant relation of starch content and intensity of bud dormancy as in Shin-Shen area. The sugar content began to increase as the bud began to burst. 3. In Pin-Tung area: The intensity of bud dormancy increased gradually from early November and reached the deepest in early January. The bud began to burst in late January. The changes of carbohydrates content is the same as in Shin-Hua area.
