摘要
对从越南、泰国引种的5个月生129个卡西亚松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;家系间发芽率和高径比差异显著。以苗高、地径和变异系数为评价指标,以改良后布雷金多性状综合评定法进行评定,初选出K108、K105、K109、K107和K104等5个优良家系。根据苗期生长数据的分析,部分引进卡西亚松优株家系已表现出生长优势,具有进一步筛选的潜力。
The growth superiorities of 129 families within 4 provenances of Pinus kesiya introduced from abroad were investigated and analyzed in the seedling stage. The height, ground diameter and coefficient of variation of P. kesiya were tested by using nested test method. The families had significant effects on germination rate and height-diameter ratio. Moreover, the improved Breggin multi-index comprehensive evaluation method was used, and by taking seedling height, basal diameter and variation coefficient as the evaluation indicators, the tested 129 families were evaluated, five superior families were screened out. They are K108、K105、K109、K107 and K104. According to the analysis of seedling stage, parts of the introduced superior families have been appeared growth vigor than others, so have excellent potential for further selection in testing trials.
