文摘内容 In order to probe the death reason of terminal buds and carry out trunk extension by using lateral buds, the temperature characteristics of dormancy development of terminal and lateral buds in Paulownia tomentosa xp. fortunei 33 were investigated by raising cutting branches on different date at 25℃ and 15℃. The results were as follows:①The death reason of terminal buds and the first pair of lateral buds was itselfe cological adapting strategy, not the injury of early frost and freezing; ② The lateral buds 2, 3 and 4 had obtained the feature of winter dormancy, and could survive from cold winter, and widen its possible temperature range of sprouting to lower temperature by experiencing winter chilling; ③The lateral buds 2, 3 and 4 could sprout at the same time in spring, but it was difficult to sprout for other lateral buds; ④ The sprouting of upper lateral buds could restrict the sprouting of lower lateral buds at 25℃, but not at 15℃。
