Dependences of changes in relative intensities of the reflected light (∆RL) at 400–500 nm (a), 500–600 nm (b), 600–700 nm (c) and 700–800 nm (d) on changes in the quantum yield of photosystem II (∆ФPSII) and the non-photochemical quenching in chlorophyll fluorescence (∆NPQ) in the second leaf of pea (n= 20). Changes were calculated as differences between values of reflected light intensities and photosynthetic parameters at 10, 20, 30 and 40 min after burning and these values before induction of variation potential; the changes were calculated for each experimental pea seedling. R is the correlation coefficient.
