摘　　要：为黔北地区竹子良种选育和竹产业开发提供依据,对该地区几种主要竹种的干缩性能进行了研究。结果表明:各竹种的干缩率之间存在一定的差异,麻竹、硬头黄、撑绿竹和吊丝球竹的各干缩率相对较大,毛脚龙竹、金佛山方竹和斑竹相对较小,其余竹种居中。另外,不同竹种的气干差异干缩、全干差异干缩也存在一定的差异,且各竹种的全干差异干缩均大于气干差异干缩,其中,毛脚龙竹、斑竹、慈竹、吊丝单竹的全干及气干差异干缩较大,麻竹、料慈竹、梁山慈和吊丝球竹的全干及气干差异干缩为中等,硬头黄、花吊丝竹、撑绿竹、云南龙竹、清甜竹和金佛山方竹全干及气干差异干缩较小。The shrinkage rate of several kinds of bamboo species in the north of Guizhou province was studied to provide the basis for fine varieties breeding and bamboo industry development. The results show that there exists some differences in shrinkage rate among the various bamboo species. Shrinkage rates of Dendrocalamus latiflorus , Bambusa rigida , Bambusa pervariabilis × Dendrocalamopsis daii and Sinocalamus beecheyanus are relatively high, that of Dendrocalamus barbatus, Chimonobambusa utilis and Phyllostachys bambusoides are relatively low and the others are moderate. Of all the different bamboo species,the whole stem shrinkage is greater than the air-dry shrinkage and there are differences in the whole stem and air-dry shrinkage among them. The whole stem and air-dry shrinkage of Dendrocalamus barbatus, Phyllostachys bambusoides, Neosinocalamus a f finis, Dendrocalamopsis vario-striata are relatively big, and that of Dendrocalamus latiflorus, Bambusa distegia, Dendrocalamus farinosus, Sinocalamus beecheyanus are moderate, while that of Bambusa rigida , Dendrocalamus minor, Bambusa pervariabilis ）〈 Dendrocalamopsis daii , Dendrocalamus yunnanicus , Dendrocalamus sapidus , Chimonobambusa utilis are small.
