摘要
对花叶女竹的笋竹生长发育规律进行了初步调查研究。结果表明,花叶女竹从4月中旬开始陆续出笋,直到6月上旬结束,共持续52天左右;退笋发生在盛期和末期,退笋高度一般小于20 cm;竹秆的高生长节律遵循"慢—快—慢"的规律,昼夜高生长量差异不明显;光照充足的林地四周,新生叶片保持白色条纹特性,但条纹长短、宽窄、位置不同;林地密集的中间地带,多具大叶秆型,叶片恢复绿色。
The rhythm of growth and development of Pleiblastus simonii（Carr.） Nakai f.heterophyllus.Muroi were studied.The main results were as follows： bamboo shoots of P.simonii Nakai f.were emerged from the middle April to the late June,which was lasted for 52d;Shoot degradation was prevalent in the peak and terminal shooting stage and the height of them was less than 20 cm;The height growth of young culms followed the ＂slow-fast-slow＂ principle,and had no difference between day and night;The leaves of bamboo in the forest with enough sunlight maintained green and white stripes,but the size and distribution of the stripes were different.On the other side,in the center of the bamboo forests,the leaves became green and larger.
