We compared the development of yield curves of mean and top height and development of mean diameter according to yield tables of beech which were constructed on the basis of short-term investigations with empirical data of repeated measurements on permanent research plots. We performed our study on 86 permanent research plots with 550 repeated measurements. The length of the interval of repeated measurements on the research plots is in the range of 10–43 years. We quantified differences in the development of model and empirical curves by help of basic statistical characteristics. The results show that the actual growth of mean heights is more intensive than in models of yield tables. An opposite situation is for mean diameters. The development of top heights corresponds to the actual growth of beech stands.
