Determining Fiber Length, Fibrillar Angle And Springwood-Summerwood Ratio in Slash Pine
Abstract:The important wood property, fiber length, can be determined rather precisely. For botanical and genetical studies only the unbroken fibers from a particular type of cell should be measured. For studies of wood pulp it is equally important to measure all fibers present, either whole or broken. A good correlation exists between fibrillar angles as determined by the x-ray and those determined by microscopic methods for Pinus elliotii Engelm. from northern Florida. Only a slight negative correlation was found between the average fiber length and the fibrillar angle. The amount of summerwood varied considerably among the different growth rings from the same tree. The width of the summerwood portion of a single growth ring varied also along its circumference and vertically along the tree axis. There is an inverse relationship between the widths of the summerwood portions of two adjacent growth rings. Until the pattern of these different variations is further clarified the proportion of summerwood can be best determined from pulp samples.
