This paper shows correlations between vessel characteristics and
differences in growth-ring width in heartwood and sapwood. Analyzed
samples were from an iron-wood tree (Gymnocladus canadensis Lam.) that
grew in the Muzljanski Rit area, of the Srpska Crnja municipality in
Serbia. According to previous research, it was deduced that Gymnocladus
canadensis Lam. belongs to ring-porous species with big vessel lumen in
the earlywood zone and thicker cell walls in the latewood. Vessels were
more numerous in the latewood zone, and the same was true for heartwood
and sapwood. For both layers, sapwood possessed a few more vessels than
heartwood, and a statistically significant difference was confirmed by
t-test during the early phase. The greatest negative value of
correlation coefficient was between the number of vessels and
growth-ring width during the early phase for sapwood. The number of
vessels decreased in the wider growth rings. The correlation between
growth-ring width and the area of vessels had a statistically
significant positive value of correlative coefficient, which means that
wider growth rings had larger vessel areas in the early phase for
sapwood.
