Comparative analysis of the anatomical structure of heartwood and sapwood selected Gymnocladus canadensis Lam. trees in Srpska Crnja

This paper shows the results obtained from the study of the macroscopic-microscopic structure (capillary system) in the growth stem of Gymnocladus canadensis Lam. originating from North America, which grows in 'Muzljanski rit' in the area of Srpska Crnja. Gymnocladus canadensis Lam. falls under the ring-porous species according to its porosity, with large tracheas in its early zone. The early zone trachea lumens, contained in the sapwood, reach dimensions of up to 160 μm, while early zone trachea lumens in the growth stem rings of the sapwood reach dimensions of up to 120 μm. Examination of the microscopic structure of this tree show good properties of the tree.Projekat ministarstva br. 3104
