Taking into account the emerging trend towards temperature increase in the region of the research in recent years, introduction and cultivation of genus Juglans in the Voronezh region is a pressing issue. The studied the dynamics of phenological phases 5 the most promising for the cultivating species of nuts (Juglans regia L., Juglans manshurica Max., Juglans nigra L., Juglans cinerea L. and Juglans cordiformis Max.), which are the most promising for the cultivating. Has been identified a significant increase in air temperature over the past 30 years. A close correlation between the temperature indicators and the dynamics of phenological phases is established (primarily occurring in the spring). With an increase in average annual air temperature by 1 °C and remaining unchanged humidity indicators, the duration of the growing season increases by an average of 4 days. Keeping in mind the emerging tendency of climate change, the cultivation of heat-loving southern forms of Juglans nuts in the Voronezh region will constantly increase.
