Introduction. There are about 4.500 plant species in the flora of Uzbekistan, 650 of which have essential oil and more than 1.000 species are medicinal (1). More than 50 types of these plants are the main raw materials in various branches of the national economy, especially in the food industry and medicine. Vitamins, alkaloids, terpenoids, glycosides, and several other chemical compounds necessary for human health will retain their properties. In recent years, the structure and properties of chemical compounds contained in many medicinal plants have been studied, and their biologically active substances have been introduced into scientific medicine (1-5).

Ajuga turkestanica (Regel) Brig. is a phytoecdysteroid-containing plant. Phytoecdysteroids are physiologically active substances with a wide range of effects. They have a positive effect on the human body with antioxidant, anabolic, hypoglycemic, and hemorrhagic effects, in the rapid healing of wounds, myocarditis, atherosclerosis, anti-cancer, bone fracture, and hepatitis treatment. Phytoecdysteroids are the basis of preparations such as Ecdisten, Ecsumid, Cytodyne, and Ecdybol, which have an anabolic, adaptogenic, and stimulating effect (6-12).

At present, these preparations are being prepared at the experimental industrial base of the institute (13-15). The plant contains phytoecdysteroids, iridoids, glycosides, flavonoids, and essential oil. Tincture and decoction of crushed stems and leaves of the plant are used in the treatment of malaria, cancer, atherosclerosis, diabetes, and myocardial diseases. Currently, it is

also used as a raw material for the perfume industry, as well as to restore physical impotence (1629). The main goal of creating a map of the distribution of the plant A. turkestanica (Regel) Brig. is to determine and map its current distribution to study the natural resources and use more of our natural flora resources in medicine. This way, it is not only possible to use all its reserves but also to determine its biological properties, stage of development giving the best content of BAS, its place in the composition of plant communities under natural conditions, the degree of emergence under the influence of anthropogenic factors and the protection committees of plant communities in need of protection.

Materials and Methods. A. turkestanica (Regel) Brig. is an endemic plant, a representative of the family of Lamiaceae. It is an undersized shrub with a height of 30-40 cm and a strong root. A. turkestanica (Regel) Brig. stem erects or ascending, sometimes with a creeping stem. The leaf is entire, three-lobed, and even three-lobed. Flowers are sessile, false ring-shaped, many-flowered panicles located in leaf axils. Corolla inverted ovate, five-toothed. The corolla dries up at the time of fruiting but does not swell. Corolla leaves are jointed with a wide base, multi-veined, reddish in color, and 2-3 cm long. There are four lateral stamens and two anterior that are longer than the laterals, and the rest stamens are reduced. The fruit is one-seeded with four nutlets of 88.5 mm long, 3-3.5 mm wide, greenish-brown seeds, 1000 seeds weigh up to 20.2 grams. The seed is without endosperm, the spine is straight. At the base of the corolla, there is a circle. The plant is pollinated by insects and various other ways. It blooms and bears fruit in April-May. Therefore, during the years 2017-2021, studies on the A. turkestanica were conducted in the southern regions of Uzbekistan, Kashkadarya, and Surkhandarya (6).

It is of great importance to study the morphological characteristics of plant organs during the stages of ontogenesis. In the period of ontogeny, the growth of organs and the organism occur, and certain biochemical, physiological, and morphological processes are observed. During the development of individuals, all ontogenetic and age-related changes occur, such as substance and energy metabolism, cystogenesis and organogenesis, strong growth and division, recovery and reproduction, and aging and rejuvenation.

The natural development of the plant, floristic and phenological observations were carried out according to the method of Beideman I.V. (30). Method of Rabotnov T.A. (31, 32) used to determine fertilization of seeds in laboratory and field conditions. To determine the germination of plant seeds in laboratory conditions, 100 seeds of the plant were collected on printed paper moistened with distilled water in a Petri dish. Freshly harvested seeds and ones stored for different periods after harvesting were used to determine the seed germination in laboratory conditions, and 4 times were germinated at 5-300C. In studying the germination of seeds under field conditions, the germination rate, optimal planting time, and planting depth were determined by planting A. turkestanica 4 times out of 100 replicates. The method of Lishchuk S.S. (33) was used to determine the weight of 100 seeds.

A. turkestanica (Regel) Brig. is widely distributed on different slopes of the mountain slope, especially on the southeastern slopes, in gravel, gypsum, turf, typical gray soils, and olagins deposits, and in the creation of the distribution map, all the requirements, working stages of other thematic methods were followed, and the map was created in the ArcMap 10.8.1 GIS program. The Maltsev I.I. (34-36) method is the most suitable for determining A. turkestanica (Regel) Brig. raw material reserves, taking into account the fact that it grows in the upper reaches of mountain rivers and meets at different heights. Walking diagonally across common areas, ten 20 m2 squares

were counted separately for the age of plants and bushes suitable for raw materials. The total phytomass for the area was obtained by multiplying the obtained numbers by the average dry weight of one plant.

Results and Discussion. The ontogeny of the A. turkestanica was divided into 3 periods and 9 growth stages. I-latent period (seed), II-virginal period (grass, young, immature and virginal, young vegetative plants), III-generative period (early flowering, middle-aged and older plants). We divided the growth and development of the studied plant into latent, virginal, and generative periods. The virginal period, in turn, is divided into three stages: grass, juvenile, and immature.

Latent period. This period includes the time from seed ripening to germination. The seeds of A. turkestanica ripen in early July. The fruit is a one-seeded four nut-shaped, dry-opening, bean-shaped (kidney-shaped), covered with 20-30 toothed hairs. In the seed, the endosperm is not developed, and the germ is located correctly. Seed viability is preserved for up to 5 years. Germination of seeds depends on cold stratification and light. Information on seed germination is not provided in the literature. We conducted experiments in laboratory conditions during the years 2018-2021 to determine the seed maturation period and the germination of seeds stored at different temperatures. As shown in the table, seeds stored in laboratory conditions (20-22°C) for 1 year have the maximum fertility (71.3%), and after 5 years this indicator is known to decrease by three times (21,2%). This result shows that the fertility of seeds decreases when they are stored for a long time (Table 1).

Thus, the germination rate is high at a temperature of 20-22°C. This feature of A. turkestanica seeds decreases during the year but is not completely lost, and it is considered suitable for germination next year.

Virginal period. 1. The grass. On 25.02.2018, 65.0-% of the seeds planted in autumn (October 2, 2017) in the experimental field of the Baysun district germinated 65.0%. Germination is above-ground, that is, epigeal, and the leaves of the plant growing above the ground. The leaves are narrowly lanceolate, 0.5 cm long, and 1.2 mm wide at the age of 10 days. In the plant, the duration of growth was 8-12 days.

2. Juvenile pressure. In the middle of March (12.03.2018), a true leaf is formed, and the height of the plant was 1.2 cm. After a few days, the growth of the plant accelerated, the height of the plant was 2,9 cm, and the width was 2,6 mm. In the second ten days of March, the height of the plant reached 5 cm, the number of leaves reached 6, and their size was 0.4 - 0.5 cm. In this case, the root depth reached 9 cm. By the end of March (25.03.), the growth of the plant becomes active as the air temperature rises. It was observed that the height of the plant is 9-10 cm, the number of leaves reaches 6-7, and their length is 0,7 cm and width is 0.4 cm. At this time, the thinnest branch was 0,4 cm long, and the leaf band was 0,2-0,3 cm long. By the end of March (30.03.), the height of the plant was 11-12 cm, the number of leaves reached 8, and their size was 0,9 cm, width 0,5 cm. Thus, in the juvenile state of A. turkestanica, up to 8 leaves were formed on the stem, and this stage of the development of seedlings lasted 15-20 days.

3. Immature head in the first ten days of April (5.04), the height of the plant reached 13 cm. The number of leaves reached 9, and their length was 0.6-0.7 cm. In this case, the root depth reaches 22 cm. By the middle of April (15.04.), the growth of branches becomes active as the air temperature rises. Plant height It was observed that 19-20 cm, the number of leaves reaches 9-11, the length is 0,9 cm and the width is 0,4 cm. By the end of April (30.04.) the height of the plant is 21-25 cm. The number of leaves reaches 14 and their length is 1,1 cm and width are 0,5 cm. This stage of development of A. turkestanica cases lasts 25-27 days. Based on the observations, the plant in the third year entered the generative period on April 25, 2020. By this time, its height was 39-42 cm, the number of stems was 3-4, the number of leaves was 23-31, and the depth of the root was 75-82 cm.

Generative period. Information on A. turkestanica generative period, flowering, and fruiting is not available in the literature. The results of our observations showed that the plant entered the generative period in the third year of its vegetation. This coincides with the beginning of May when flower buds appear from the axils of the leaves from the third joint to the 9-10 joint of the main stem. At the end of May, single buds in the axils of 8-9 pairs of leaves begin to open. During this period, the height of a 3-year-old plant reaches an average of 24-26 cm, and the growth of the plant slows down. The opening of flowers of A. turkestanica mainly lasts from the end of April to the end of May. The flower opens as follows: the buds that should open the next day differ in size and weight compared to others. The corolla leaves are higher than the corolla leaves, and the next day the buds begin to open as they mature. Corolla leaves are jointed with a broad base, multi-veined, reddish in color, and 2-3 cm long. During the opening of the flower, the pollinators are tightly attached to the pistil, 5 hours after the opening of the flower, the pollinators move away from the pistil towards the petals, leaving the remains of the pollinator sealed in the form of pollen grains around the tip. The pods of seed pods are head-shaped and hairy at the top. 1 day after the opening of the flower, the beak parts begin to separate from the middle part, and by the 3rd day, the beak parts are completely separated and remain separate will remain under the muzzle. At this time, the corolla darkens and begins to shrivel. By the 5th day, the beak changes from red to pinkish-red, on the 6th day, the rind dries up on the beak, and the fruit is formed. So, it takes 6

days for the bud to fully open and the petals to spill out. Some parts of the mature pollen grains, that is, the places where the pollen nests stick together, are covered with a thick cuticle. As a result of the tests, it was found that there are a large number of pollen grains in 9 mm long buds, the length of the pollen grain is 4 mm, and the length of the pollinator thread is 1 mm. During the period before the bud matures and the flower opens, the anther grows imperceptibly, its length reaches 4,4 mm, and it is considered to be another at this time. In the generative period, the tap root of the plant reaches up to 80 cm, and its branches up to the 4th order. The base of the root is strongly woody. At the end of the first year of vegetation, 7-8 joints are formed on the branch. In the second and subsequent vegetation years, annual shoots begin to grow from 2-3 pairs of buds in the joints of the main part of the surviving stem of the previous year, these branches do not branch. In the second year of vegetation, the branches grow monopodial i.e., the tip bud is open, the plant root grows strongly up to 50 cm, lateral roots of the 4th order begin to appear from the main root, the lateral root of the 2 nd order develops strongly and grows parallel to the main root. The third year of vegetation of A. turkestanica falls at the beginning of March. In this case, annual shoots grow from 3-4 pairs of buds on each plant, and their growth continues from mid-march to the end of April. At this time, the height of the annual branch reaches 24 cm, and 6 pairs of leaves appear. 4-5 pairs of leaves are 3,4-3,7 cm long and 1-1,2 cm wide. At this time, a branch of the second order is formed in the axil of the leaves at the 2-3 joints and starts to grow together with the branch of the first order. From the end of April to the middle of May, the growth and development of the plant slow down.

Flowering biology of Ajuga turkestanica. It is very important to study the reproductive biology of medicinal plants, to reproduce them, to determine their raw materials, to cultivate wild species, and to determine the laws of adaptation to living conditions. Reproductive biology -studies the laws of plant reproduction. Among the scientists who developed this line of science; O.A. Ashurmatov, Kh.Ch. Boriev, J.Yu. Tursunov, Kh.Q. Karshiboev (37-39) and other scientists explained the laws of reproductive biology in their works. Turkestanica belongs to the category of day thermophilic plants. Flowers begin to open in open weather, at a temperature of 20°C, from 8-9 in the morning. Flowers were observed to open from 8:00 am to 5:00 pm in the Baysun district experimental field. Its flowering rhythm has changed a lot due to air temperature (35°C) and other factors of the external environment. So, it was observed that the total flowering period of this plant lasted 44-46 days from the middle of April (15.04) to the end of May (30.05). In order to determine the daily flowering period of this plant, 10 plants were selected and observed from 6 am to midnight. The number of opened flowers in each bush was counted and then cut off. At the same time, air temperature (30-35°C) and humidity (55%), and sunlight (80.000 lux) were calculated (Figure 1).

Root productivity of Ajuga turkestanica. The most important biological characteristics of plant seeds are formation, the structure of seeds, and physiological processes occurring in them. The life of each individual begins with the germination of a seed and ends with the formation of a seed. In this process, the complete transition or non-transition of plant phases is compared and analyzed depending on the ecological factors of the place where it is grown, and the naturalness of the indicators is shown. As a result of many years of research, the number of generative and vegetative stems in A. turkestanica has changed depending on their growth in different environmental conditions. seed yield studies were conducted during 2018-2020. Up to 65 branches

were formed on each bush of A. turkestanica growing under natural conditions in the Kashkadarya and Surkhandarya regions. Each plant produced up to 72 flowers.

Due to the very warm weather in 2018, the flowering of plants started much earlier (15.04). In 2019, the flowering period was observed later (18.05) due to good weather and prolonged rainfall. 2020, when the phenology of A. turkestanica was observed in the experimental field of the Baysun district, the plant began to bloom on April 29. The period of fruiting lasted longer than flowering, depending on weather conditions.

We studied fruit sets based on the beginning of the flowering process, total flowering, completion, and location of the flowers on the stem (bottom, middle, and top). The highest number of opened flowers and set fruits was observed during the beginning of flowering and the period of total flowering. At the beginning of the flowering period, an average of 72.7 flowers were formed on one stem per plant. In the experimental field of the Baysun district, it was observed that the fruit yield was high for three years. But, due to the change of weather, some of the buds did not have time to form flowers. At the end of flowering, the buds and flowers formed are relatively small, and only 50-55% of the seeds of the fruit are fully ripened (40) (Table 4).
