摘要：

A new analytical instrument has been developed for rapid measurement of the transverse dimensions of tracheids in Australian plantation-grown Pinus radiata, The instrument combines scanning x-ray microdensitometry and image analysis to produce radial profiles of tracheid diameter, wall thickness, coarseness and other wood morphological characteristics. The tracheid diameter and density measurements are performed automatically on polished radial wood sections cut from increment cores. Corrections are made for the unavoidable deviations from radial alignment of the cores. The initial purpose of the instrument is to provide comprehensive information for tree breeding and silvicultural programs with particular emphasis on pulping and papermaking characteristics.
