N2 - The crown of model trees growing in natural habitats is characterized. An attempt was made to identify more conservative and stable traits of crown axes of different orders. The dependence of the composition of shoots of second-order axes on their position in the first-order axis of the maternal growth is shown. The relationship between the lifetime of the axes and the time of their growth (aging) is revealed. Skeletal axes of the second order show similar pattern of changing the number of shoots from year to year, but differ in the length of their constituent shoots. The axes of the third, fourth and fifth orders determine individual differences of trees, by adjusting them to specific habitats. It was revealed that the change in the dominance of the fourth order over the third one in the crown reflects the regulation of the crown development under specific conditions and the rate of ontogeny.
