Variation trends of wood property along stem in Salix suchowensis
摘要
Abstract
The intra-individual variations of the basic density and the contents of main wood chemical compounds, inclu-ding cellulose, hemicellulose and lignin, along stems of S. suchowensis were measured in this study. Statistical analyses revealed that the basic density and the main wood compounds along the stem varied as following:the wood basic density decreased from stem base to stem top, in range of 0.331 2-0.385 4 g/cm3 for the measured samples. The contents of cel-lulose, lignin and hemicellulose were in ranges of 48.69%-56.89%,12.58%-16.42%,19.83%-23.76%, respectively, for the measured samples. Contents of cellulose and hemicellulose were found to decrease from stem base to stem top in all the measured samples. By contrast, lignin content exhibited a different variation trendency. For all measured samples, the lowest content appeared in the middle of the stem, and it increased towards both ends, with the highest lignin content appeared at the top of the stem. However, ANOVA statistics indicated that the basic density and the main wood chemical compounds varied insignificantly along the stems within individuals, while they varied significantly among different indi-viduals.关键词
