| 摘 要： | According to the strategy for the development of China paper industry, wood as a pulping material resource will play more and more important roles in the coming years1,2]. Due to the deficiency in forest resources, the wood harvesting of natural forest has been strictly constraint in China. So the intergradation of aforestation and manufacture of paper products has become an important way to ensure a reliable material resource for China paper industry1,2,5]. Many fast growing wood projects … |

| Abstract: | The fiber morphology variation of triploid clone of Populus tomentosa Carr. and the supposed harvesting age for the paper industry were investigated in this paper. The results shows that in the first few years, 2-4 years for example, the fiber length at breast high grows faster than it does in the later years. But the standard deviation of distribution in fiber length at breast high in mature wood is larger than in the young tree. The technologically harvestable age of triploid clone of Populus tomentosa Carr., BL304 could be 4-7 year old to meet the requirement for paper industry. The distribution of fiber length become concentrated within an annual ring as the tree grows. The test results also show that the cloned poplar has a small Runkel ratio value (less than 0.4, generally about 0.3), and this ratio increases slightly with the tree grows. |
