参试种源 15个 ,家系 6 1个 ,采用尼龙网圃地遮荫育苗技术 ,随机区组设计。对苗木主要生物量指标进行了方差 ,多重比较和聚类分析等综合性研究。种源或家系间苗木的全高、地上及地下部分、径粗、分枝数、秋梢高生长、干鲜重等主要性状均有显著差异。筛选出苗期表现较好的福建德化、永泰、仙游 3个种源和德化 2 1号等 17个家系 15 kinds of provenance sources, 6 families, using nylon net nursery shading technology, randomized block design. The main biomass indicators of seedlings were studied by variance, multiple comparisons and cluster analysis. The seedlings of provenances or family lines had significant differences in the total height, above-ground and underground parts, diameter and number of branches, height growth of autumn shoots, dry and fresh weight. Three germplasm sources, Fujian Dehua, Yongtai and Xianyou, and 17 families, including Dehua No. 21
