茶秆竹新竹生长规律的研究

通过对茶秆竹的鞭芽及幼竹－－成竹生长规律的观测，结果表明：茶秆竹的鞭芽于8月上旬开始分化，鞭芽数随着鞭龄的增大而降低。当年的鞭可以分化成鞭芽和笋芽，茶秆竹立竹主要集中在壮龄和中龄鞭上，立竹的着生部位以鞭的中、后段为主。竹笋出土可分为3个时期，高生长可分为4个阶段，高生长节律呈S形，符合Logistic曲线。

Research on bamboo Growth Regularity of Pseudosasa amabilisMcCl.Current Research on Bamboo Culm Form

Based on the observation of bamboo scourge buds and bamboo growth of Pseudosas a amabilis McCl. The results show that it is the first ten days of August that the scourge buds begin to polarization, and the older the scourge is,the less t he scourge buds are. They can grow into scourge buds and shoot buds.The bamboo l ocates strong and middle scourge mainly,and they are in middle or later part of the scourge.
