The radial variation of the density of occurrence of vertical resin canals in selected coniferous species

Abstract

This study determined the radial variation of the density of occurrence of vertical resin canals on the cross-section of selected coniferous species. The tests were carried out on the wood of pine (Pinus sylvestris L.), spruce (Picea abies L.) and larch (Larix decidua Mill.) originating from dominant trees at an age of 104-106 years, growing in the same habitat and climatic conditions. The test material consisted of approximately 30 mm thick discs cut out from every test tree at the diameter at breast height. The measurements of the analysed parameter consisted in determination of the number of vertical resin canals per unit area of the cross-section, within the squares located from the core to the tree circumference. The obtained results suggest interspecies differences in the density of vertical resin canals. The coefficient of correlation between the density of vertical resin canals and the width of annual rings of the tested species was also diverse.
