Periodic monitoring (by age stages) of the growth energy and health of trees has been performed in population cultures of white birches established on a half-sib basis (for the first time in Russia). The results show that the pattern of growth and development and the health (survival) of provenances tested in population cultures depend primarily on the ecobiological properties of birch species and also on the distance and direction of seed transfer.
