The informativeness is established of the method of induction of chlorophyll fluorescence for bioindication in the conditions of anthropogenic influence on the example of T. officinale plants, by the parameters: F0, Fm, Fst, Fv, Fv/Fm та k1, k2. The main parameters of the induction curve can be used as test indicators to determine the resistance of plants to adverse factors. Changes in these indicators characterize the processes associated with the influence of the environment on the course of both light and dark phases of photosynthetic processes in chloroplasts. The photosensitivity of T. offic- inale leaves, which indicates the physiological state of plants, decreases with increasing adverse external influences. It is established that the plants of T. officinale have the maximum intensity of photosynthesis, which grow in more favorable ecological conditions control. Therefore, the use of the device «Floratest» to determine the condition of plants at different levels of anthropogenic load is promising and requires further research.
