摘要：

本文根据61个单叶省藤家系、31个版纳省藤家系和83个黄藤家系5年生试验林的生长表现,以10%的入选率、不低于1.96的选择强度,初步筛选折算单位面积产量高的单叶省藤家系6个、版纳省藤家系3个和黄藤家系8个,产量比参试家系群体总体平均值分别高111m/667m2、124m/667m2和598m/667m2。研究结果为高产棕榈藤家系早期选择提供依据,有助于高产棕榈藤品系的早日育成。

摘要：

One-year-old seedlings of 61 half-sib families of Calamus simplicifolius,31 half-sib families of C. nambariensis var. xishuangbannaensis and 83 half-sib families of Daemonorops margaritae were outplanted in northeastern Guangzhou in April 2004,and their growth performance were measured in March 2009. With selected proportion at 10% and selection intensity not less than 1.96,6 half-sib families of C. simplicifolius,3 families of C. nambariensis var. xishuangbannaensis and 8 families D. margaritae were selected,the production of which was 111 m,124 m and 598 m more than the mean production of all families tested. The result is useful for early selection and breeding of high-yield rattan families.
