Abstract: In the conducted studies, the issues of the flowering phase, fruiting and seed formation of trees and shrubs common in the north-eastern part of the Greater Caucasus (Azerbaijan) were studied comparatively under ex situ and in situ conditions. The trees and shrubs studied in the course of the study were divided into early-ripening and early-ripening (TT), early-ripening and moderately conservative (TO), moderately early-moderately conservative (OO), late-early-late conservative (GG). Most of the studied species were included in the group that begins flowering in the middle period and ends in the middle period. The results of the phenological observations showed that there is no direct relationship between the duration of flowering and the life of the flower. When comparing the characteristics of flowering and fruiting of the studied plants under ex situ and in situ conditions, no difference was found between the duration of flowering and the life of the flower between the plants in both conditions. Depending on the bioecological characteristics of plants, it was found that the preservation of fruits formed in ex situ conditions varies within 1.8-6.4%, and in situ conditions - within 3.1-68.6%. Plants in natural conditions had a fruit-preserving capacity that was 5-10% higher than in cultivated conditions, depending on the variety. Natural conditions have more favorable environmental factors for normal flowering and fruiting of plants. Since the studied plants grow in nature in the north-eastern regions of the Greater Caucasus, the difference between these regions is the dry subtropical climate of the Absheron Peninsula, where they were introduced. Considering the normal flowering and fruiting characteristics of plants studied in ex situ and in situ conditions, it is possible to preserve their gene pool in cultural conditions and use it in landscaping.
