摘要
对设在福建三明和仙游 2个试验点 1 0 5个 9a生的马尾松自由授粉子代试验林进行了调查研究。结果表明 ,不同家系在树高、胸径、材积生长性状上存在极显著差异 ,这些差异主要由遗传因素控制 ;在木材基本密度、木材化学组分、木材纤维形态、通直度、圆满度性状上也存在较大的差异。以单株木材干物质产量为主要指标 ,从三明点选出W0 0 2 5 1、W0 0 2 5 5等 9个建筑材优良家系 ,从仙游点选出W0 0 3 0 8、W0 0 2 98等 9个建筑材优良家系 ;以单株纤维素产量为主要指标 ,从三明点选出W0 0 2 49、W0 0 2 5 1等 1 0个纸浆材优良家系 ,从仙游点选出W0 0 3 0 7、W0 0 3 3 5等 1 0个纸浆材优良家系。上述入选的优良家系不但单株木材干物质产量或单株纤维素产量高 ,而且具有明显的生长优势 ,增产效果显著 ,可在生产上推广应用。
The analysis of variance was adopted to study the genetic variation of 105 9-year-old open-pollinated progenies of Pinus massoniana at Zhongcun Felling and Silvicultural Farm of Sanming and State-owned Forest Farm of Xikou ,Xianyou,Fujian Province. The results showed that there were significant differences at 0.01 level among families in growth traits such as height,DBH and stem volume, and the variations were mainly controlled by genetic factors. There were also differences among families in wood basic den...
