用竹材解剖特征鉴别肾耳唐竹与满山跑竹

在无限花序的竹类中,大节竹属与唐竹属亲缘关系最为接近,两者无论在生殖器官或营养器官方面(地下茎、分枝特性)均十分相似,尤其是从营养体看,难以区别〔‘,“1。为此,笔者试图用竹材形态解剖结构特征,论证这两个疑难竹种是否属于两个属的不同竹种。

DISCRIMINATION OF SINOBAMBUSA NEPHROAURITA FROM INDOSASA ALBO-HISPIULA BY WOOD ANATOMICAL COMPARISON

Indosasa albo-hispiula was often confused with Sinobambusa nephro-aurita when outer morphology of their vegetative bodies was observed. Argument was that if they are two species under two different genera. Wood anatomical comparison revealed that there were distinct differences in the type of vascular bundle, epidermis, hypodermis and cortex between these two species, Besides, anatomical similarity existed between I. albo hispiula and species in genus Indosasa McClure, and S. nephroaurita and species in genus Sinobambusa Makino. The conclusion is that I. albo-hispiula should be put in genus Indosasa McClure and S. nephroaurita in genus Sinobambusa Makino.
