Inter-regional variability and effect of the recent period 1959-1993 . The aim is to model the dominant height growth of Querciis petraea. revealing possible effects of the region or of the recent period on the shape or level of the past growth curves of ageing stands. The data are the growth of 50 stands from five regions 153 years old on average reconstructed from stem analyses. A flexible mathematical model was used with oblique asymptote the slope of which may vary with the level of the curve in the set and with six parameters common to all curves to account for their shape and one parameter proper to each curve to account for its level site index . The fitting like the data themselves exhibit a sustained growth rate till the end of observations. When analysed according to age. the residuals reveal a significant shape difference between one region and the other ones when analysed according to date they show an effect of the recent period which could partially be an artefact due to the measurement method but without any impact on our modelling of the past growth.
