构属植物韧皮解剖结构及化学组分的制浆适用性研究
Study on the Pulping Applicability of Phloem Anatomical Structure and Chemical Composition of Broussonetia Plants
摘要
Abstract
The anatomical structure and chemical composition of three Broussonetia plants phloem(Broussonetia papyrifera,Broussonetia kazi-noki,Broussonetia kaempferi Siebold)were studied,and the micro-region distribution characteristics of lignin and pectin were observed.The re-sults showed that the phloem of three Broussonetia plants exhibited many similarities in terms of anatomical structure and chemical composition.Compared with Broussonetia papyrifera and Broussonetia kazinoki,the phloem fibroblasts in the Broussonetia kaempferi Siebold were more close-ly arranged,accounted for a higher proportion in the phloem,and had a higher content(63.31%)of holocellulose.The lignin content of the phloem of three Broussonetia plants phloem(approximately 14%to 16%)was lower than that of common wood and straw,and it was mainly de-posited in the phellem layer,parenchyma tissue and phloem rays.The pectin content was 7%to 10%,and it was mainly distributed in the phlo-em rays,phellogen,and parenchyma.关键词
