【摘要】 选择 9种有代表性的三倍体毛白杨无性系和 1个普通毛白杨 ,对其化学组份和纤维特性进行分析测定 ,试验结果用灰关联决策的理论和方法进行综合分析评价 ,对三倍体毛白杨无性系纸浆材进行选优。分析结果表明 ,三倍体毛白杨无性系中L1,L5 ,L6为优良的短周期纸浆材 ;用灰关联决策的理论和方法对短周期纸浆材进行选优是可行的更多还原

【Abstract】 The research is conducted focusing on the variation in the fiber morphology of 9 triploid clones and 1 normal clone of Populus Tomentosa carr. The Grey_connection_decision method is applied to the selection of the Populus Tomentosa carr.Triploid Clones. Results indicate that three clones L1,L5,L6 are selected out as the excellent clones for pulping and papermaking and the Grey_connection_decision method is workable of applying to the selection of the fast_growing wood for pulping and papermaking.更多还原
