Within the framework of a project conducted jointly with the Forest Research Institute, staff of the Plant Anatomy Laboratory conducted a novel study on the effect of an increase in stem temperature (caused by direct exposure to solar radiation) on xylem formation within the trunks of Robinia pseudoacacia trees. Samples of the vascular cambium and associated tissues were taken for analysis from the southern (exposed) and northern (shaded) sides of tree trunks growing in the interior of the tree canopy and in its peripheral zone. The results of the study indicate that an increase in trunk temperature (caused by direct exposure to solar radiation) can be considered as a factor affecting the radial growth of R. pseudoacacia before full leaf development. Moreover, the results of the study suggest the need to take into account the varying rates of xylem cell deposition within tree trunks when designing studies on the early stages of xylogenesis in ring-necked species.
