Fiber characteristics and chemical composition of three Taxodium ‘Zhongshansa’ woods and pulping evaluation

Taxodium ‘Zhongshansa’ (T. ‘Zhongshansa’) is a hybrid cultivar of the Rich. genus. The wood and fiber characteristics chemical compositions three T. specimens were analyzed compared with their parents, mucronatum mucronatum) distichum distichum). It was found that density hybrids slightly lower than densities parents. average length to width ratio samples similar greater Runkel ratios smaller patents. Compared extractives contents hardly varied, while lignin content lower. result kraft cooking bleaching T.Z.502 indicated yield 44.9%, kappa number pulp 41.8. easier delignify via oxygen alkali, brightness reached up 76% ISO after an elemental chlorine free process. results provide reference for application in paper making future.
