N2 - Tree crown formation in ontogenesis is a realization of spatial and temporal development program. Based on the study of young individuals of U. glabra growing in a natural oak forest, the presence of two groups of axes was shown. One group creates the axes of crown base - "skeleton". The other one appears at a certain age and creates the so-called "crown lace"- a short-lived and replaceable base for photosynthesis. The transition from the formation of the skeletal part of the crown to the next stage, which occurs in the 4th branching order, the shoots of which are significantly shorter, and their number is greater, is quantitatively shown.
