摘　　要：文章对收集的版纳省藤家系进行苗期生长变异的观察,结果发现:家系间根长和芽长及叶片数和最大叶长都存在极显著的差异;叶片数和最大叶生长与气温关系显著,叶片数和最大叶生长趋势相似,移苗后的2、3个月生长最快,12月至次年的2月生长缓慢;主成分分析选出6个优良家系,其中4个分布在勐腊尚勇地区。The variation of seedling traits were investigated based on the field data of 28 progenies of Calamus nambariensis Becc. var. xishuangbannnaensis S. J. Pei et S. Y. Chen families. Differences in all seedling traits were significant at 0.01 level among families. The results revealed the correlation of air temperature with both the leaf number and the largest length. The growth trend of leaf number was same as that of the largest leaf length, The growth of most progenies reached its climax in the first two or three months after bedding out, while slowed down from December to following February. On the basis of principal component analysis, 6 superior families were singled out for higher genetic gains, 4 belongs to Shang,cong, Mengla.
