Photosynthetic responses of oak seedlings (Quercus petraea, Q rubra and Q cerris) to drought were investigated using gas-exchange and chlorophyll fluorescence. Decreases in predawn leaf water potential (ψwp) led to pronounced reductions in both stomatal conductance (gw) and net CO 2 assimilation rate (A). In contrast, the maximal photochemical efficiency of photosystem II (PS II) measured predawn (Fv/Fm) remained unaffected until complete cessation of CO2 assimilation. Responses of PS II photochemical efficiency (ΔF/Fm') to increasing photon flux density (PFD) were determined for leaves of both control and water-stressed seedlings. Drought resulted in a stronger reduction of ΔF/Fm. at a given PFD in Q rubra and Q petraea, but not in Q cerri...
