| 摘 要： | 本文利用樟子松 ( Pinus sylvestris L .var mongolica L itvin) 1 1个种源在科尔沁沙地 3个参试点的生长性状 ,进行联合方差分析。结果表明 :各种源树高间存在极显著差异 ;通过在各试点进行多维空间、多向量数学模型的综合分析 ,得出青山种源的生产力最高 ,高生长超出章古台 (对照 ) 3 0 .4 %,超出参试种源平均值 1 3 .5 6%,高峰、塔河、呼玛次之。经相关分析 ,樟子松不同种源树高与冠幅、当年生长量、地茎呈显著正相关。

| Abstract: | Analysis of in alliance was carried out on the growth of 11 provenances of Pinus sylvestris L.var mongolica litvin at three sites.The result showed that the difference among the provenances was significant.The synthetical evaluation of multivarriables and the correlation analysis which based on the growth factor of the tree were also produced .Qingshan provenance was the best,whose height was 13.5% and 30.4% higher than the average of all provenances and Zhanggutai (the control) respectively;Gaofeng,Tahe,Huma provenances were better.There were extremely significant positive correlation between tree height and collar-diameter,crown size,as well as annual height incnement of 1998. |
