Morphometric parameters of Armeniaca mandshurica in the arboretum of Reshetnev Siberian State University of Science and Technology

The research was carried out using the facilities of the Arboretum of Reshetnev Siberian State University of Science and Technology, located in the green belt area of Krasnoyarsk (Russia). The research objects were trees of Manchurian apricot and their morphometric parameters, such as height, trunk diameter, crown diameter, and leaf lamina size. The studied biogroups are grown in the Arboretum departments of mother plants (“C” – Arboretum Department, “D” – Far Eastern Flora Department). The results obtained when studying the growth and fruit-bearing capacity of mother trees are generalized. It was shown that 50-year-old trees of A. manchurianus growing in the “C” Department outperform other plants in terms of plant height, trunk and crown diameter. The maximum leaf lamina size was revealed in plants of the Far Eastern Flora Department (“D”). Fruiting intensity was assessed using Kapper’s scale. The biogroups of Armeniaca mandshurica produce fruit in the arboretum conditions with the periodicity of 2–3 years, except for the years when generative buds and flowers are damaged by late spring frosts. During the observation period, 2021 and 2023 became the leading years in terms of fruit number.
