摘要
倭竹族隶于禾本科之竹亚科。本族计有10属约150余种。分布于东南亚季风带的印度、越南、中国及日本等国,我国产8属约120种,占该族全部属种的80％。其中唐竹属、短穗竹属、筇竹属、八月竹属等均为我国所特产,唐竹属1种早期引入日本栽培,倭竹属、大节竹属、方竹属、刚竹属等也主要分布于我国,只有少数种分布于其它国家,业平竹属和阴阳竹属为日本特产。 刚竹属计有70种之多,我国产50种以上,是本族中种类最多的属,其中有许多种类分布广、适应能力强,用途多、产量大。是重要的植物资源.尤其是毛竹,是我国亚热带地区的主要栽培竹种。 倭竹族花序演化的研究对于进一步认识和鉴别竹类植物.了解竹类植物的演化关系。使竹类植物的系统安排更加合理都是有益的。倭竹族的花序属于假花序.与真花序相比较属于原始类型。本族中花序轴反复分枝.具有极多小穗的短穗竹属,业平竹属等是比较原始的,大节竹属、唐竹属的花序简化、花序轴不分枝或仅有少数分枝,含小穗数很少是进化类型。
The present paper deals with the morphological evolution of inflorescence in the tribe Shibataeeae Nakai. Studies show that the inflorescence in the tribe belongs to the pseudoinf lorescence type, which is relatively primitive when compared with the euinflorescence type. In the tribe Brachystachyum and Semiarundinaria which have a repeatedly branching inflorescence axis and numerous spikelets are relatively primitive; on the other hand, Indosasa and Sinobam-busa have the simplized inflorescence, in which the axis doesn't branch or only has a few branches and fewer spiklets, are considered to be advanced relatively.
