Differential analysis of fiber characteristics and chemical properties between tetraploid Paulownia fortunei and its diploid
摘要
Abstract
The difference of fiber characteristics and chemical properties between seven-year tetraploid and its diploid Paulownia fortunei were investigated in this paper.The results showed that the trends of wood fiber length,width,fiber aspect ratio,wall thickness,wall cavity ratio and diameter cavity ratio of tetraploid Paulownia fortunei are basically same with the increase of Paulownia fortunei tree age and height,but rangeabilities are different.The wood fiber length,fiber aspect ratio,wall thickness,wall cavity ratio and diameter cavity ratio of tetraploid Paulownia fortunei were larger than those of the diploid; The fiber width is smaller than that of the diploid.The content of cold water extracts,hot water extracts,1％ NaOH extracts,benzene-alcohol extracts and lignin of tetraploid Paulownia fortunei respectively decreased by 4.47％,5.08％,12.24％,4.47％ and 20.09％ ; While the content of cellulose and holocellulose of tetraploid Paulownia fortunei content increased respectively by 3.54％ and 3.57％.Analysis shows that tetraploid Paulownia fortunei are more suitable as papermaking raw materials.关键词
