Ⅰ、引言 1979年7月24日生长在京都大学Kamigamo实验林站的24株毛竹全都开花。同时,生长在Yokohama500m~2上的200株毛竹也发生了。这二块竹林由MAEDA1912年采收的种子萌发而培育出同一无性系构成的。两块竹林同时开花,对论述毛竹开花周期提供了一个很有趣而又有价值的记载。从毛竹种子培育到开花记载在日本确实是第一次被承认,即使其他竹种也很少记载。
I. INTRODUCTION All 24 mosses grown on July 24, 1979 in Kamigamo Experimental Forest Station, Kyoto University flowered. At the same time, 200 bamboos grown on Yokohama 500m ~ 2 also occurred. The two bamboo forests were organized on the same basis by MAEDA in 1912. Two bamboo plants bloom at the same time, which provides a very interesting and valuable record on the flowering period of bamboo. It is indeed the first time that the cultivation of bamboo seeds to flowering records has been acknowledged in Japan, even though other bamboo species are rarely documented.
