Resources of some useful species of the Euphorbiaceae family distributed in the Nakhichevan Autonomous Republic of Azerbaijan

Phytocenological analysis and identification of the resources of some species of the Euphorbiaceae family with medicinal properties distributed in Nakhichevan Autonomous Republic is the main goal of the studies. So, a phytocenological assessment of the composition of 12 formations on the territory of 3 districts was carried out. Reserves of 7 dominants and subdominants species of these cenoses were calculated. Associations Chrozophora hierosolymitana - Nepeta micrantha - Stachys fominii, Trifolium pratense + Lotus corniculatus + Euphorbia iberica + Achillea millefolium, Euphorbia seguieriana + Cotenaster melanocarpa + Serinte minor + Betula pendula are the most common planting groups in general vegetation cover. Species Chrozophora tinctoria (328.0-311.4 g/m2), Chrozophora hierosolymitana (269-223 g/m2), Euphorbia iberica (214 g/m2), Euphorbia virgata (203.2-181.7 g/m2) and Euphorbia seguieriana (289.0-361.1 g/m2) are distinguished by the highest rates of biological reserves.
