摘要

Four lichen species: Hypogymnia physodes, Pseudevernia furfuracea, Parmelia saxatilis, and Platismatia glauca were collected from two sites(S. Poland) with a different air pollution level:" Kamienica valley" (less polluted) and "Kopa" (more polluted). The thalli were compared with respect to their: net photosynthetic rate(P_N), fluorescence parameters(Fv/Fm, Fm, Fm/F0), chlorophyll a+b content, and phaeopytinization quotient (O.D.435/O.D.415). P_N intensity, chlorophyll a+b and O.D.435/O.D.415 were reduced only in P. Furfuracea collected from Kopa, which is in agreement with the Hawksworth-Rose Scale of sensitivity of lichens to air Pollution.
