Distribution and Current State Cenopopulations of Helichrysum maracandicum Popov ex Kirp. in Uzbekistan

The current state of coenotic populations of rare and endangered species of Uzbekistan Helichrysum maracandicum is given. The range of species distribution is broad. The article contains 12 cenopopulations of Helichrysum maracandicum in Uzbekistan, which have considerable healing properties. During the researches, no censorship marks were recorded in any cenopopulation. Approximately, 1, 5, 11 censorpopulations were found to be close to optimal conditions. This indicates that adequate amounts of precipitation in these areas throughout the year have a positive impact on the growth and development of the plant. Most of the cenopopulations were transmitted to younger and transient states.


Introduction
The development of industry and agriculture and the extensive use of natural areas lead to the breakdown of the ecological balance. As a result, there is a risk of diminishing the number of plant species. Despite the relatively good overall state of the species preserved in the national reserves, natural resources of many wild species are sharply declining.
Especially demand for medicinal plants is rising day by day. This affects the status of species in natural populations. Among these species are H. maracandicum, which plays an important role in terms of medicinal activity.
However, there have been no studies on cenopopulations and natural re-

Research Objects and Methods
The object of our research is the type of H. maracandicum spread throughout Uzbekistan ( Figure 1).
H. maracandicum's cenopopulations were evaluated on the basis of a number of organisms and population signs [1].
During the study, 12 cenopopulations (CP) of H. maracandicum were evaluated a number of organisms and populations have been studied to assess the state of cenopopulation. The reliability of differences between the mean values of the marks studied was evaluated according to the criteria of Student. The reliability of markers in screeners is less than 2.0, and the relative censorship values are close to each other. Characters with a score of 2.0 or higher mean the difference between the average values. For all organism marks, the mean value of the 10 rats of the generative age was derived from all cenopopulation.
Transects were laid a length of 10 m, they were divided in area for 1 m 2 . Each coenopopulations laid from 10 to 30 sites over 1 m 2 . Ontogenetic structure cenopopulation was defined as the ratio in populations of individuals of different Smirnova [2] and classification "delta-omega" of L.A. Jivotovsky [3]. Delta (Δ)-An index of population age [4], which assesses the age level of coenopopulations at any moment of time, and omega (ω)-The effectiveness of the plant i-ontogenetic state (the value of "load" on the energetic resources of environment, expressed as a fraction load produced by middle-aged generative condition plants of this population. According to this classification, the CP can be young, ripening, transition, aging and old. The population density was determined by the number of individuals or biomass on per unit area. Particular attention was paid to the average density, i.e. the number of per unit whole space or ecological density-the number of per unit habitable space that can actually be occupied by population [5]. Geobotanical descriptions were made by standard methods at the sites of 100 m 2 [6]. Plant name was given by Cherepanov [7].

Results and Discussion
To estimate of the coenopopulation state as organismic traits we selected: Plant  Table 1). The evaluation results are presented in the form of a multi-axis chart.
In order to assess the state of the cenopopulation, each of the characters has been divided into five groups of the same size. Then each group is given a score, which is the lowest point. The results of the assessment of the state of cenopopulation are reflected in the multi-diagram ( Table 1)     were recorded in these cenopopulations. In these cenopopgrats, the density of dyes does not exceed 5.1, the ecological density of the trees is about 4.25 -6.05. It was noted that the proportion of young players in the censorship does not differ from each other. This is due to the fact that the plant has a high potential for potential productivity and vegetative growth of the herbaceous. Particularly in one plant bush, there are between 35 and 80 baskets. The shaped baskets contain between 50 and 80 potent seeds. This is one of the most important factors in the recovery of cenopoplastic seeds. Given the fact that the plant is harvested locally, it is important that cerebral palsy be found in general. Decrease of generative buds in cenopopulation will naturally lead to a decrease in the number of seedlings in the next year.
During the study, the types of cenopopulation were analyzed. According to him, most cenopopulations were age-specific and transient (Figure 3).

Conclusion
In recent years, due to the rapid development of agriculture, anthropogenic pressing has been observed in wildlife. This situation is also reflected in the transformation of many natural areas into cultivated areas by the local population, and the rarely growing species of rice cultivation for commercial purposes.

Thus, the diagnosis of H. maracandicum's cenopopulations states that none of the surveyed populations showed a maximum coincidence of the sum of characteristic values. This approach to the environment has resulted in a reduction in H. maracandicum's natural habitat and a sharp decline in some cenopopulations. The accurate geographical coordinates of these cenopopulations will then be used to conduct monitoring activities in those areas.
