ECOLOGICAL ASSESSMENT OF THE CENOPOPULATIONS OF SOME SPECIES OF IRISES IN THE GANJA-GAZAKH REGION
The increasing anthropogenic impact on the places of natural growth of plant communities leads to the fact that the population of wild ornamental irises decreases from year to year. The aim of the study is to determine the limiting environmental factors affecting the distribution of certain species of irises (Iris L) in the Ganja- Gazakh region. The assessment of the potential and real ecological valence of species was carried out, the coefficient of ecological efficiency and the tolerance index of species were calculated. With the help of amplitude ecological scales, it is possible to determine the state of the growing environment in the response of the cenopopulation to changes in certain environmental factors. It was revealed that the species of irises growing on the territory in the Ganja- Qazakh region. Are assemblers in the structure of ecological and cenotic groups, and changes in the soil and climate of the region can be determined by their condition in the cenopopulation. The results of the research can be used in phyto-indication of territories and monitoring of plant resources.
