The terminal buds of Machilus seedlings grown in the Subtropical Zone were not induced into the dormacy requiring chilling for its release and had a relatively wide range of temperatures suitable for bud break(Table 4 and 5). So the terminal buds often sprout in the winter in Mie and then are killed by frost. On the other hand, the terminal buds of Macilus seedlings collected from the Temperate Zone could be induced into the dormancy requring chilling for its release(Table 4 and 5)and sprouted in spring without frost damage in Mie. This dormancy,however,could not be induced with short-days at the temperatures ranging from 18 to 28℃(Fig.5-8). The relationship between photoperiod and temperature seems to play an important role in inducing dormancy. And photoperiod seems to have a great effect on the growth patterns, that is, the relationship between leaf initiation and internode growth(Fig.9).}, pages = {147--156}, title = {樹木の休眠に関する研究(IV) : タブノキの生態型と休眠の相互関係}, volume = {4}, year = {1990} }
