In the magazine Trees - Structure and Function An article has been published on the relationship between the divisive activity of the cambium and the formation of vessel members within the radial rows of secondary xylem cells.
The analysis was based on the transverse preparations made of branches of four species differing in the type of vascularity (i.e., with ring-vascular wood and spread-vascular wood). It was found that the formation of vasculature/vasculature within the selected radial rows of cells results in a reduction in the frequency of periclinal (additive) divisions within the cells of the vascular cambium (initial/maternal cells) belonging to these rows. The obtained results were interpreted, among other things, based on the assumptions of the tigmo-osmotic hypothesis, which explains the basis of the mechanism of radial growth of dicotyledonous trees (also known as the tensile stress hypothesis - the "tensile stress hypothesis"). tension stress hypothesis). A theoretical explanation of the observed relationship was proposed, including the temporal effect of the change in mechanical stress due to the formation of a vessel member on the occurrence of periclinal divisions in the vascular cambium.
