The study of the anatomical and morphological characters of varieties and hybrids of Dianthus barbatus L plants and the identification of decorative characteristics by the color of flowers and their decorativeness is relevant in the technology of their cultivation. We studied the height of the shoots and the size of the bush, the diameter and doubleness of the inflorescence, to maintain constant characters in cross-pollinated species, since these characters vary greatly and are not constant within the variety and hybrid. Dianthus barbatus L plants have several biological characteristics that give them advantages over other flowering species. The high potential for the formation of many seeds is accompanied by reliable methods of their reproduction, due to the seeds preserved in the soil. Dianthus barbatus L represent a combination of different shades in one inflorescence - from white to maroon. The impact of numerous, both natural and anthropogenic, unfavorable environmental factors can lead to a decrease in plant productivity, therefore we carried out a comprehensive assessment of resistance based on anatomical and morphological characters and ecological methods of influencing the physiological characteristics of Dianthus barbatus L.
