Abstract
Using the statistical analysis of leaf wator potential (ψ daily course of forest tree species (Quercus cerris, Acer campestre andCarpinus betulus) we have determined the optimal times of ψ measurement (i.e. at 08.00, 10.00 and 16.00) making possible the calculation of the ψ daily course resp. ψ-value at any time. The accuracy of the calculation does not deviate much from the errors of ψ measurement. The probable error of a single ψ-measurement was forQ. cerris 0.06 MPa and for bothA. campestre andC. betulus it was 0.05 MPa.
