| 摘 要： | 对3种基质,4个种源的2年生柔枝松容器苗的年生长规律及其形态指标进行了分析,并运用主成分分析和聚类分析,对12个处理苗木进行了质量评价。结果表明,3-4月份、5-8月份,地径处于迅速生长阶段;而苗高只在4-5月份整个生长季中唯一一次高生长,期间地径生长缓慢。P3种源的年生长规律与其他种源有较大不同,即地径生长起止时间相对较早,苗高生长期较长。对17个形态指标进行主成分分析和聚类分析,并结合方差分析。结果表明,M1基质容器苗的苗木质量较差;M2、M3基质的苗木质量较好,其中又以M2基质P1种源和M3基质P2种源的苗木质量更佳。

| Abstract: | The annual growth dynamics and morphological indices of two-year-old Pinus flexilis container seedlings of four provenances grown in three substrates were analyzed,and seedling quality evaluations of twelve treatments were analyzed,using principle component and cluster analysis.It was found that diameter at root collar was rapid growing from March to April and May to August.And height of seedlings only grew from April to May during the whole growing season while the growth of diameter at root collar was poo... |
