Responses in young Quercus petraea: coppices and standards under favourable and drought conditions
Original language description
Assimilation and photosynthetic efficiency (maximal quantum yield) of young oaks were comparednin coppice and standard sessile oak stands of comparable age (100 years) under different light intensityncategories: under minimum light – ISF < 20%, low light – 20%<ISF<25%, medium light – 25%<ISF<30%nand in the open, without mature canopy cover – ISF >30% during favourable and drought conditions.nMeasurements of maximal assimilation rates were performed at a constant temperature of the measurementnblock (20°C), a CO2 concentration of 400 μmol/l, flow 500 μmol/s and different light intensities: 0,n50, 250, 600, 1200 and 1800 μmol/m2s during three consecutive growing seasons (2012, 2013 and 2014).nIn every category at least 8 young naturally regenerated seedlings and sprouts of different coppice stoolsnwere measured. The quantum yield in optimal conditions in standards was highest in the category of closedncanopy, while in coppices in medium light category. During severe drought in 2013 the drop in efficiencynof standards was evident in all categories, while in coppices no differences in efficiency were observed betweennfavourable 2012 and 2013 with expressed drought stress, proving the advantage of young coppicesnover standards in this particular light category. However, the beneficial effects of restoration coppicing arennot guaranteed. It is our belief that in time such advantage might decrease; it would be therefore interestingnto compare responses in time and define, when response abilities of both studied systems become equal.
