16个竹柏种源在南平地区的苗期试验结果表明:竹柏不同种源苗木,在苗高和地径生长等方面存在着显著差异;竹柏苗木生长具有明显的种源效应,其中苗高、地径的生长速度与产地经纬度变化无明显相关,而是表现出典型的随机变异模式.本文通过多点试验、随机区组设计、方差分析、相关分析和聚类分析等方法,对1-3年生各种源苗木的生长,主要是苗高、地径的生长状况进行分析比较,初选出福建延平、浙江金华等5个表现突出的优良种源.
The results of seedling experiment of 16 provenances in Nanping area showed that there were significant differences in the seedling height and diameter growth between seedlings of different provenances. The growth rate of diameter is not significantly related to the latitude and longitude of origin, but shows a typical random variation pattern.In this paper, by multi-point test, randomized block design, analysis of variance, correlation analysis and cluster analysis, The growth of seedlings of various sources, mainly the growth of seedling height and diameter, were analyzed and compared, and five excellent provenances with outstanding performance such as Yanping in Fujian Province and Jinhua in Zhejiang Province were selected.
