Indicative plants with nitrogen indicator in the flora of the Nakhchivan Autonomous Republic
One of the important factors in the life of plants is the element nitrogen, a macronutrient. Nitrogen plays an important role in the early development of the vegetative organs and fruits of plants. Nitrogen plays an irreplaceable role in the synthesis of enzymes involved in plant metabolism. It also plays an important role in the growth and development of plants. The excess and deficiency of nitrogen, an important nutrient, significantly affect plants. Determining the amount of nitrogen in plants by indicative plants is the main object of modern agrochemical research. The amount of nitrogen is studied through chemical analysis of soils. However, the development of these methods requires a lot of additional costs, chemical reagents, and manpower. The determination of nitrogen deficiency or excess amount using indicator plants is one of the main objectives of modern researchers. As an indicator of nitrogen, wild and cultivated plants are used.
