Models for early development of Scots pine (Pinus sylvestris L.) cultures are presented. The sample consists of 100 temporary plots, of which 71 are seeded and 29 planted. Annual increments for fifteen years were measured. The data of 819 growing periods is used in analysis. Sites are described using site indexes which are determined by dominant height and 5-year increment of dominant height. Site index estimates are compared with site indexes of forest site types. The development of dominant height is described using a 5-year increment model. The base model describes current annual increment of basal area u.b. Initial state for growth models is given as basal area u.b., when either dominant height has reached 1.3m or cleaning has been done. Bark, volume, mean height, and diameter models are also derived. Growth tables may be simulated for different sites and initial number of stems for planted or seeded, cleaned or uncleaned sapling stands with a dominant height of up to 10m.
