摘要：为了能够筛选出苗期表现优良的加勒比松家系和进行苗期选择研究,对9个种源92个加勒比松优株家系苗期生长指标进行测定,并采用巢式数据分析方法进行分析。在引种地和育苗地(造林地)间气候趋于一致的前提下,生长测定结果表明:苗高、地径和高径比3个苗期生长指标在种源和家系间均达显著性水平;发芽率在种源和家系间则未达显著水平。采用聚类分析法筛选出最优良家系为C65和C96,较优良家系为C2、C40、C41、C93和C97。
In order to find the superior family in seedling stage and to study growth superiority of the finefamily, 92 families within 9 provenances of P. caribaea introduced from abroad were investigated in theseedling stage. Germination, seedling height, ground diameter and height-to-diameter ratio were measured.The results showed that factors of family and provenance had significant effect on seedling height, grounddiameter and height-diameter ratio, but had no significant effect on germination. The weather of introducedarea and plantation site tended to be identical. According to the result of cluster analysis, the best familieswere family C65 and C96, the better families were family C2, C40, C41, C93 and C97.
