Аннотация: The aim of this study was to analyse the geographical variation found in the timing of anthesis in Scots pine. In the adaptaion of the generative cycle to local climatic conditions, the geographical adaptability weighted with the so called Linsser's law is a particularly intersting point. Geographical correlations calculated against distances measured along simulated post-glacial migration routes were stronger than purely latitudinal correlations. Effects of the reinvasion of Scots pine into Finland are thus still visible in pine populations. In light of flowering phenology it seems probable that the northern populations of Scots pine in Finland have still not completely adapted to the prevailing cold climate at these latitudes. A moderate warming of the climate would therefore be beneficial for Scots pine.
