ELEMENTAL COMPOSITION OF THE AERIAL PARTS OF COUSINIA MARACANDICA PLANTS

Abstract

This study presents a comprehensive analysis of the elemental composition of the above-ground parts (leaves and stems) and seeds of Cousinia maracandica, an endemic plant species of Uzbekistan. Using modern methods such as high-resolution scanning electron microscopy (SEM) and energy-dispersive X-ray spectral analysis (EDS), the distribution of major macroelements (e.g., K, Ca) and microelements (Fe, Mg, P, Ti) in the plant tissues was determined. The comparative analysis revealed that the above-ground parts of the plant have high concentrations of carbon, oxygen, and potassium, suggesting high metabolic activity. In the seeds, the predominance of oxygen, phosphorus, and magnesium supports energy accumulation and enzymatic processes. The relationship between the distribution of these elements plays a crucial role in understanding the ecological adaptation and life strategies of Cousinia maracandica. This study enriches theoretical knowledge of plant physiology and morphology and provides practical insights into the impact of environmental conditions on the biologically active substances in medicinal plants. The results contribute to the in-depth study of the ecological, biomorphological, and chemical characteristics of Central Asian flora
