Abstract

The article presents the results of studying the growth of magnolias shoots, provides information about the features of their seasonal rhythm of growth and development, and also assesses the prospect of their use in landscaping of the Republic of Belarus. During the research, the growth rate of shoots was measured in 2 varieties and 5 species of magnolias, phenological observations were carried out for 4 species, 1 subspecies and 3 varieties of magnolias, and based on the data obtained, the prospects of the studied samples of magnolias for use in landscaping of the Republic of Belarus were evaluated.

Phenological observations during the period 2019–2021 have shown that magnolias are very sensitive to climatic conditions, and each phase corresponds to its own level of heat. The average duration of flowering of magnolias for the period 2019–2021 of the study was 14–20 days. The warmer the weather conditions, the longer the flowering period lasts.

To determine the intensity of the growth of shoots, measurements of the magnitude of their growth during the growing season were carried out. Shoots from the lower and middle parts of the crown were measured. In the apical branches, the growth rates of shoots were higher compared to the lower and middle ones due to the greater illumination by the sun. Based on the measurements carried out, the dynamics of the growth of shoots for magnolias has been established.
