  • 【Objective】 In order to improve the survival rate and reduce the cost of afforestation,by comparing the growth difference of the seedlings from two provenances of Chimonobambusa utilis,and the excellent seedlings were selected for afforestation in the mountains. 【Method】 In this study,the seeds of Qingba and Huanglian from Tongzi County of Guizhou Province were selected for seedling cultivation,and the growth of annual seedlings from the two provenances of Ch. utilis was compared. 【Result】 The results showed that each index of annual seedlings from two provenances increased with time in a positive proportion,and the growth of each index was small in winter due to the influence of air temperature,the maximum plant height and ground diameter of annual seedlings from Qingba provenance were better than those from Huanglian provenance,but the number of tillers and number of leaves from Huanglian provenance were better than those from Qingba provenance. 【Conclusion】 Through cluster analysis,three indexes of maximum plant height,ground diameter and number of tillers from annual seedlings of Ch. utilis were selected as the comparison indexes,and the seedlings were divided into four grades,grade Ⅰ (excellent),grade Ⅱ (good), grade Ⅲ (medium) and grade Ⅳ (poor),which is expected to provide theoretical basis for the cultivation and introduction.
