The publication is devoted to the issues of influence of environmental factors on pigments that determine the color of plants and reflect the physiological indicators of plants: normal development and growth, which determine the main life process - nutrition - photosynthesis. Photosynthesis is a key biochemical process of formation of organic matter starch from inorganic, the course of which depends on environmental conditions, environmental factors in combination with the work of chlorophyll determining the intensity and productivity of reactions. Chlorophyll is a green pigment that plays a special role in the absorption of sunlight. Plant pigments are not only coloring agents, but also indicator substances, they are most sensitive to anthropogenic pollution and conditions of soil, air and water. Thus, by the degree of intensity of coloring in green, one can draw a conclusion about the state of the environment and the health of plants. Conducting a study on the impact of pollutants on the state of the environment and the analysis of environmental factors using the express method - bioindications occupies a central place in the system of monitoring activities and is of current importance for sustainable development and rational nature management. During the study, analyses were conducted of endemic species of the genus Tulipa in the city and region during various periods of ontogenesis to identify the effects of a natural set of conditions.
