Abstract
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.
Highlights
The development of industry and agriculture and the extensive use of natural areas lead to the breakdown of the ecological balance
Research on the current state of cenopopulation allows the study of ecological optimum species at the level of population and organism level
The object of our research is the type of H. maracandicum spread throughout Uzbekistan (Figure 1)
Summary
The development of industry and agriculture and the extensive use of natural areas lead to the breakdown of the ecological balance. There is a risk of diminishing the number of plant species. 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. Research on the current state of cenopopulation allows the study of ecological optimum species at the level of population and organism level. Scientists have noted that in assessing the state of cenopopulation, individual and population optimally are differentiated. Scientists have developed a number of methodological manuals that can help identify the optimal, critical and pessimistic cenopopulations
