ANALYSIS OF ADAPTATION OF LEMNA MINOR TO DIFFERENT GROWTH CONDITIONS AND ITS MORPHOPHYSIOLOGICAL AND BIOCHEMICAL INDICATORS

In this study, the growth characteristics of the aquatic plant Lemna minor under the influence of various environmental factors were studied. In particular, the development processes of the plant were evaluated depending on the light intensity, the composition of the nutrient solution, and the pH level of the medium. During the experiments, the increase in biomass, the number and size of leaf plates, the amount of chlorophyll, the activity of the photosynthesis process, the concentration of total protein and pigments were determined and analyzed. The results of the study showed that this plant is sensitive to environmental factors. Also, the obtained data confirm the possibilities of effective use of Lemna minor as a bioindicator and in biotechnological directions.
