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.

在本项研究工作中，以研究阿塞拜疆南部地区在现代生态环境下的生物多样性为背景，确定了属于柿属（Diospyros L）的高加索柿种（Diospyros lotus. L）的基因库。对高加索柿种（Diospyros lotus L）这一物种在区域生物多样性中的遗传资源进行了鉴定，并研究了该物种基因库的保护与可持续利用途径。基于对生物生态特性的研究，明确了研究物种在区域生物多样性中的地位、分布区域、影响其的自然和人为因素，以及其减少的原因。研究表明，在该区域生物多样性的各种种群中，根据形态学、生物学和经济指标，存在不同形式的高加索柿种（Diasporus lotus. L）。这种差异出现的主要原因是兰卡兰-阿斯塔拉地区的气候温和、雨日与晴日丰富、湿润空气团和土壤肥力的积极作用。随着海拔的升高，高加索柿种（Diasporus lotus. L）在兰卡兰-阿斯塔拉地区山麓的花期孕育和开花强度，根据温度和土壤的矿物质成分，呈现递减趋势。
