Dormancy can be understood as a manifestation of adaptation by an individual species to its envirnment. Research on the nature of various types of dormancy of some tree species distributed in different environments from northern cold areas to southern subtropical areas seems to give useful information about the process of adaptation to the environment. These comparative studies may supply some promising clues to various important problems in the physiological fields.Machilus thunbergii Sieb. et Zucc. is distributed continuously from Okinawa Pref. to Aomori Pref. in Japan. And the seedlings from Iriomote Island, Okinawa Main Island and Amami Island are not able to survive in the winter in Mie Pref., but the ones from Kochi Pref., Mie Pref., Chiba Pref., Iwate Pref., and Aomori Pref. are able to survive. The seedlings from different environments may display different natures in regard to dormancy.

休眠可以理解为一个物种对环境适应的表现。对分布在从北方寒区到南亚热带不同环境中的一些树种的各种休眠性质的研究，似乎可以提供有关适应环境过程的有用信息。这些比较研究可能为生理学领域的许多重要问题提供一些有希望的线索。et Zucc.在日本从冲绳县到青森县连续分布。而西表岛、冲绳本岛和奄美大岛的幼苗在三重县的冬天也无法存活，但是高知县的三重县，千叶县，岩手县，和青森县都能活下来。不同环境下的幼苗，其休眠性可能不同。
