Seedling Evaluation and Selection of Phoebe zhennan Superior Provenances and Families

摘要: 对从四川省9个县（区）收集的44个桢楠优株家系苗期生长指标进行测定和分析。采用嵌套式试验分析，结果表明，种源和家系间的苗高和地径均具有极显著差异。种源间苗高和地径变异系数分别在0.23~0.42和0.15~0.28之间，家系苗高和地径变异系数分别在0.05~0.43和0.10~0.34之间。以苗高、地径为评价指标，以改良后的布雷金多性症状综合评定法进行评定，初选出都6、9和4号3个优良种源，31、22、32、6和38号5个优良家系。根据苗期生长数据的分布，部分桢楠优株家系已表现出生长优势，具有进一步筛选的潜力。Abstract: The seedling growth indexes of 44 superior families were investigated and analyzed which were collected from 9 counties in Sichuan.The variation of height (Ht) and diameter of ground length (DGL) were tested by the nested test method.The results showed that there was a highly significant difference in Ht and DGL between provenances and families.The variation coefficient (VC) of Ht and DGL among provenances was 0.23~0.42 and 0.15~0.28,separately.The VC of Ht and DGL were 0.05~0.43 and 0.10~0.34 among families,respecitively.Three provenances (No.6,9 and 4) and five families (No.31,22,32,6 and 38) as superior ones by improved Breggin multi-index comprehensive evaluation method,taking Ht and DGL as the evaluation indicators,the tested 9 provenances and 44 families were evaluated.According to the analysis of seedling stage,parts of the superior families showed higher growth vigor than others,which had excellent potential for further selection in testing trials.
