Coenopopulation and microelement composition of the plant orchis purpurea, common in different ecological conditions of Azerbaijan

Abstract

The areas of distribution of purple orchid growing in the Gusar and Khizi regions, and the state of the plant in these regions were determined. Studies show that the 6 coenopopulations studied in both districts are incomplete coenopopulations. Some physical and chemical properties (pH, EC and heavy metal content) were studied by taking soil samples from the rhizosphere of the plant. Soil pH indicators were determined in the range of 5.3-7.3, EC 143.8-718 μS cm-1 in Khizi and Gusar districts, respectively. After studying the amount of heavy metals (Cu, Co, Cd, Zn, Pb, Br) both in plant and soil samples, it was found that their amounts are relatively high in the soils of the Gusar region and, regardless of the distribution area, Cu is located in the aboveground organs of the plant, and Zn, Pb, Cd is more collected in tubers.
