Abstract

The purpose of the present study was to determine the effectiveness of the chlorophyll fluorescence method induction for the estimation of the functional state of the photosynthetic activity of plants. The study was done using the "Floratest" prototype portable device. It was found that the representative plants in three ecological zones have a significant difference of indexes, what, through the changes of the chlorophyll fluorescence induction, reflects the processes of energy transformation at the early stages of photosynthesis. It was stated that value of Kpl plateau in the Kautsky curve can be used as a test for the early selection of the horse chestnut forms, resistant to the influence of the complex environmental factors. The results in bean leaves indicated that the fluorescent indices are sensitive to the effects of such stressors as acidification, salinity, dehydration.
