Spectral characteristics of photosynthetic pigments of wheat and maize plants, effected by cadmium ions and salicylic acid, were studied. Cadmium impact initiates pigment absorption maxima shifts, what indicate appearance of insignificant amount of pigment derivatives. Decrease in the number of absorption peak shifts influenced by SA confirmed its protective role in stressful conditions. [Cd]-chlorophyll was not detected in extracts from examined plants, hereby indicating indirect effect of Cd ions on chlorophyll.
