Branching and terminal growth of lateral shoots and needle growth of Scots pine ( L.) is investigated as a function of the whorlâs position and age and prevailing light climate. Number of buds per whorl was linearly and positively related to the whorlâs position and prevailing light climate. The growing whorlâs number counting from the apex was associated with declining bud number. The terminal growth of lateral shoots increased exponentially within the values 0.6â1.0 of the whorls position. Under these values the terminal growth was negligible. The growing whorlâs number indicated curvlinear decrease in shoot growth respectively, and only negligible growth occurred when the whorlâs age exceeded 10 years. The shoot growth was linearly related to the prevailing light climate but differences between dominating and dominated trees were apparent. The distribution of needle growth in the crown system was similar to that of shoot growth.Pinus sylvestris
