The influence of increasing doses of salicylic acid (SA) on selected physiological parameters and the content of coumarin-related compounds of diploid and tetraploid cultivars of Matricaria chamomilla plants were studied. Forty-eight hours after treatment SA showed growth-promoting effect with decrease in tissue water content, chlorophylls and soluble proteins. High doses of SA led to an increase of reactive oxygen species (hydrogen peroxide and superoxide radical) resulted in membrane damage (measured by accumulation of malondialdehyde). Changes in secondary metabolites accumulation in leaves were also observed. The pattern of quantitative changes of studied compounds was similar in tetraploid and diploid plants. The content of herniarin and its precursor (Z)- and (E)-2-β-D-glucopyranosyloxy-4-methoxycinnamic acid increased simultaneously. A considerable increase of umbelliferone and decrease in chlorogenic acid was registered. The rise of ene-yne-dicycloether in treated plant was also detected.
