Characteristics of steppe vegetation of Daridag
Статья научная
The article provides information about the steppe vegetation type of the Darıdag area. The study determined that the cereal-miscellaneous mountain xerophytic steppe vegetation is locally widespread at an altitude of 1500-1900 m above sea level in Darıdag. This vegetation type is primarily found on steppe brown and grey-brown soils. A distinctive characteristic of the steppe vegetation is its predominance of grasses, with a notable absence of trees, and the presence of unique plant organisms that thrive in steppe conditions. The main dominants of the subalpine groupings of true steppes characteristic of the steppes of the Darıdag area are the dense grass-forming species Festuca valesiaca , Stipa lessingiana , Koeleria pyramidata , and Agropyron pectinatum . Despite the short-rooted Bromus riparius species being characteristic of the local vegetation, the grouping formed by its dominance is very random. The steppe vegetation type in the area is classified into two formation classes, two formation groups, and 12 associations.

The territory of Nakhchivan Autonomous Republic of the Republic of Azerbaijan is rich in fodder plants. Despite this, pastures and hayfields in livestock farms are not used for their direct purpose. This, naturally, negatively affects the development of livestock breeding. As is known, plants of legume family are rich in nitrogen. Animals grazing regularly in these areas develop various gastrointestinal tumours when eating the wet mass of the plant. For this purpose, legumes should be used as dry feed. During 2024, studies were conducted to investigate the forage and chemical composition of Vicia elegans Guss species, including its distribution. Starting from early spring months, pastures and hayfields on the territory of the Batabat plateau were surveyed, and the use of the species ‘ Vicia elegans Guss’ in animal husbandry was studied. During the study, the ratio of dry matter and protein in leaves and stems of the plant collected from the Batabat plateau was determined.

Effect of plants used for whooping cough and their content of biologically active substances
Статья научная
Azerbaijan is a country with the richest medicinal resources in the world. Favorable climatic conditions, fertile soils, abundant sunlight, and sufficient water reserves create the basis for the growth of various types of valuable medicinal plants here. In the cold months, phytotherapy is used not only for treatment, but also for prevention. Among infectious diseases caused by cold weather, whooping cough prevails over others. There are enough medicinal plants and natural remedies to eliminate the main symptom of the disease, coughing and irritation caused by suffocation. The composition of plants used in whooping cough is rich in saponins, mucus, glycosides, flavonoids, and essential oils. Extracts, infusions, and cooking made from them, taken in a certain dose, increase the body's natural defenses and prevent the disease from becoming chronic. Experts have given rules on how much and in what ratio to take them. The use of fresh air in combination with phytomedicines for whooping cough is even more effective. Since treatment with phytotherapy is effective, it has been used at all times and research is constantly being conducted in this direction.

Factors Influencing the Decline of Biodiversity in Azerbaijan
Статья научная
The natural vegetation and its flora of Azerbaijan are exposed to anthropogenic influences, leading to a decrease in the number of a number of valuable plant individuals or their complete destruction. The main result of the factors affecting the reduction of biodiversity in Azerbaijan is the disruption of the ecological balance of the country, which threatens rare and endemic species. As a result of the reduction of biodiversity, the ecosystems of Azerbaijan are weakened and rare species are at risk of extinction. The sustainability of natural resources and the environment is seriously threatened. As a result of the disruption of ecosystem stability, the ability of local populations to use natural resources is limited and the resilience of ecosystems to climate change is reduced.

In modern times, the study of biodiversity in the context of global climate change is becoming more and more important. The study area is the Batabat Plateau, located in the north of the Nakhchivan Autonomous Republic, on the southern slope of the Zangezur Range. The area surrounded by the Zangezur and Daralayaz ranges has such geographical conditions that the air humidity is below normal for most of the year. Only in the summer months does the humidity increase relatively. Due to the flow of moist air entering the area through the Bichanak pass, which is a low area of the Zangezur range, the humidity of the air is relatively high, which is very important in the formation of vegetation. As a result of our research, it was found that 968 species of plants belonging to 58 families and 344 genera can be found in the flora of the Batabat plateau, and the flora spectrum of the area was prepared by us. The species of plants distributed in the Batabat plateau were analyzed according to their life forms and useful properties, and it was found that the plant groups formed by these species contain a quantity of technical medicines, fruits and berries, and other useful products that will provide a number of industries (food, medicine, perfumery, etc.). Plant groups have abundant natural resources, which are used effectively.

The study of the Salicaceae Mirb. species common in the flora of the Nakhchivan Autonomous Republic was conducted and their floristic analysis was performed. In the flora of the autonomous republic, 17 Salicaceae species belonging to 2 genera were identified, 9 species were assigned to the genus Salix L., and 8 species to the genus Populus L. Types of areas: boreal areal type (7 species), xerophilous areal type (4 species), Caucasian areal type (4 species) and desert areal type (1 species). The areal type was not determined for one species. This family is of great interest both in terms of biological diversity and ecological significance. It was established that the greatest species diversity of the family is found in the middle mountain zone, and a small part is found in the low and middle mountain zones, as well as in the subalpine zone. At present, the issues of adjusting botanical-geographical and historical plant systems, analyzing the distribution and genesis of species, and clarifying typical ranges are extremely important.

Hawthorn (Crataegus) is a plant consisting of various species of thorny shrubs or small trees belonging to the Rosaceae family. The genus Hawthorn (Crataegus L.) has 20 species in the flora of Azerbaijan and 20 species in the Nakhchivan Autonomous Republic: Crataegus pontica C.Koch., Crataegus orientalis Pall. ex Bieb., Crataegus meyeri Pojark., Crataegus szowitsii Pojark., Crataegus pentagyna Waldst. & Kit., Crataegus pseudoheterophylla Pojark., Crataegus cinovski Kassymova., Crataegus sanguinea Pall., Crataegus curvisepala Lindm., Crataegus caucasica C. Koch. Hawthorn species are found in various ecological zones, including mountainous, flat and semi-desert areas. The climatic conditions of each region affect the phenological stages of plant development. In the Nakhchivan Autonomous Republic, hawthorn is found in almost all altitude zones (800-2500 m). The greatest amplitude of distribution belongs to the species Crataegus orientalis. It is found in areas from the foothill zone to the subalpine zone (900-2250 m). In the middle zone, the species C. cinovskisii, C. szovitsii, C. Tournefortii, C. pojarkoviae and C. pontica are predominantly common. However, in some cases, the distribution zone of the species C. pontica goes down, and the species C. pojarkoviae rises to the high-mountain zone. The species Crataegus caucasica, C. rhipidophylla, C. pseudoheterophylla and C. zangezura are found almost from the low-mountain zone to the subalpine zone, and the species C. atrosanguinea and C. eriantha are found in the low-mountain and middle-mountain zone. The distribution zone of the species C. meyeri sometimes reaches an altitude of 2350 m. The flower lump of the hawthorn species, which is used as a food and medicinal plant, is used in the treatment of cardiovascular diseases and to regulate heart rhythm. Ripe fruits are also useful for lowering blood pressure in folk medicine. The fruits and flowers of hawthorn are used in medicine to treat cardiovascular diseases, circulatory problems and high blood pressure. The plant is rich in flavonoids, antioxidants and tannins, so it strengthens the immune system and has an anti-inflammatory effect. Hawthorn is also used as an ornamental plant.

Genetic characteristics of honey bee breeding in the Ganja-Gazakh region of Azerbaijan
Статья научная
Beekeeping is one of the oldest and most profitable sectors of agriculture. Since ancient times, humans have bred, propagated, and maintained honey bees ( Apis mellifera L.). The favorable soil and climatic conditions, along with the rich flora of Azerbaijan, create an ideal environment for the development of beekeeping. One of the challenges in bee breeding research is that honey bees mate in the air, often at considerable distances from their colonies. This complicates controlled breeding efforts. To address this issue, selection specialists are exploring artificial insemination techniques and the establishment of controlled mating zones. This article examines the development of beekeeping in Azerbaijan, with a particular focus on honey production in the Western region. Additionally, it explores the most effective modern approaches to bee breeding, especially in the context of increasing resistance to adverse environmental factors, which has become a critical priority in contemporary apiculture.
