BIODIVERSITY OF THE CAUCASUS PERSIMMON (DIASPORUS LOTUS L) IN THE LANKARAN-ASTARA REGION.

In our research work, against the background of studying the biodiversity of the southern
region of Azerbaijan in modern environmental conditions, the gene pool of Caucasian
persimmon species (Diospyros lotus. L) belonging to the persimmon genus (Diospyros L) was
determined. The genetic resources of the Caucasian persimmon (Diospyros lotus L), belonging to
the persimmon genus (Diospyros L) in the biodiversity of the region, were determined and the
ways of protection and sustainable use of the gene pool of this species were studied. Based on
the study of bioecological characteristics, the place of the studied species in the regional
biodiversity, the distribution areas, the natural and anthropogenic factors affecting it, and the
reasons for its reduction were established. It has been established that in the biodiversity of the
region in various populations, according to morphological, biological and economic indicators,
there are different forms of the Caucasian persimmon species (Diasporus lotus. L). The main
reasons for the appearance of such a difference are: the mildness of the climate of the LankaranAstara region, the abundance of rainy and sunny days, the positive effect of humid air mass and
soil fertility. Depending on the temperature and mineral composition of the soil, the conception
and intensity of the flowering process of the Caucasian persimmon (Diasporus lotus. L) in the
foothills of the Lankaran-Astara region decreases as it rises above sea level.
