PECULIARITIES OF PIGMENTATION OF GRASSY PLANTS IN CENOSIS AT DIFFERENT STAGES OF PYROGENIC SUCCESSION
A research on the dynamics of pigmentation of grassy plants in cenosis at different stages of pyrogenic succession has been done. A decrease in general pigmentation and in content of chlorophyll A and an increase in content of chlorophyll B as well as carotenoids from the first stages of reproduction after fire to the following ones have been discovered. A decrease in the chlorophyll A and B amount-to-carotenoid ratio has been observed, which shows its increase in content.
