Leaf growth parameters, pigment composition, chlorophyll fluorescence, leaf gas exchange were studied in saplings of Fagus sylvatica regenerating in contrasting environments of forest understory, forest edge and deforested area. Saplings showed the highest chlorophyll content per dry mass, and the smallest specific leaf weight and carotenoid pool in the forest understory. Chl a/b increased with increasing growth irradiance. Photosynthesis rate (Pn) was low in the forest understory and increased in the forest edge and clear-cut area. During the period of light saturation of photosynthesis around midday the depression of potential photochemical efficiency Fv/Fm (10%) appeared in the latter habitats but the decline of Fv/Fm was more rapidly reversible in the forest edge than in the forest area. Light responses of the actual photochemical efficiency (ΔF/Fm') of saplings were different in the three habitats. ΔF/Fm' declined with the light intensity at smaller extent in the forest edge and clear-cut area than in the forest interior.
