The composition of the carbohydrates in the middle lamella and secondary wall of tracheids from black spruce wood

Abstract

Carbohydrate analyses were performed on fractions of tissue from the middle lamella and secondary wall of black spruce tracheids. The concentrations of glucose and mannose were found to be smaller in the middle lamella than in the secondary wall while the concentrations of galactose, arabinose, and xylose were slightly larger in the middle lamella than in the secondary wall. The results obtained are compared with data available in the literature for other softwood species.
