Study of ontogenetic structure and density of the coenopopulation of Hedysarum atropatanum Bunge ex Boiss. flora of daridag

The article presents findings from a study of the demographic structure and density of the population of the species Hedysarum atropatanum Bunge ex Boiss., which is widely distributed in the Daridag area. A total of ten ontogenetic states (seed, seedling, juvenile, immature, virginile, young generative, middle aged generative, aged generative, subsenile and senile) of the H. atropatanum species were observed. The processes of ontogenesis, which can be classified as normal, fast, or slow, were identified as the primary mechanisms driving species evolution. Additionally, instances of developmental disruptions, rejuvenation, and the manifestations of aging were observed. The majority of individuals belonging to the species H. atropatanum exhibit a normal to rapid growth rate. It has been observed that the process of ontogenesis is slower in areas with high plant density. It was determined that the secondary quiescence period does not manifest during the initial stages of development; rather, it becomes feasible only after the individuals have reached the virginal state. It has not been observed that immature individuals bypass the virginal state and immediately transition to mature generative plants. The vitality status of the individuals was determined based on a comprehensive analysis of multiple morphological traits, including the height of the specimens, the number of shoots, the number of flower carriers, the length of the leaves, the size of the leaves, and the number of flowers in the flower group. Following the statistical processing of the data, three classes of vitality were identified. A study revealed that individuals of the second vitality level of the H. atropatanum species are more prevalent in the coenopopulation. The optimal habitats of the H. atropatanum species are characterized by sparse grasslands with a projected cover of no more than 10-35%.
