18年生尾巨桉无性系木材纤维形态和基本密度变异研究
Study of Variation on the Wood Fiber Formation and Basic Density of 18-year-old Eucalyptus urophlla × Eucalyptus grandis Clone
摘要
Abstract
The wood fiber formation and basic density of 18-year-old E. urophylla ×E. grandis clone were studied. Results showed that wood basic density, fiber length, the ratio of fiber length to width, wall thickness, and the ratio of cell wall to lumen tended to be increased at radial positions. There was significant negative correlation between fiber length and basic density and between the ratio of cell wall to lumen and fiber lumen, while positive correlation between fiber width and fiber lumen and between the ratio of cell wall to lumen and wall thickness. The fiber formation and basic density of different radial positions showed significant differences, but between different trees they were inapparent.关键词
