Abstract
The article analyzes the stages of phenological development of 3 species of the genus Magnolia L. In the research work, the biology of leafing, budding, flowering, fruit-bearing of some species belonging to the genus Magnolia in Absheron conditions was studied on a scientific basis. The vegetation period of the species we studied was studied and climatic factors that positively or negatively affected this period were studied. The studied species were divided into groups according to the onset of flowering and the duration of this period. Thus, the entry and duration of Magnolia L. species in the Absheron region depends on the meteorological and climatic factors of the region where they are introduced, especially the air temperature and relative humidity.
