Annikki Mäkelä, Pertti Hari, Seppo Kellomäki. (1980). Eco-physiological studies on young Scots pine stands. III. Silva Fennica vol. 14 no. 3 article id 5080. https://doi.org/10.14214/sf.a15021

The proportions of needle and wood in current-year shoots in crown systems of young Scots pine (Pinus sylvestris L.) trees was studied. The proportion of needles out of the total shoot biomass increased according to the increasing number of the whorl counted from the apex. In the lower part of the crown system the needle biomass of newly-formed shoots was 50–60 fold compared to that of wood and bark biomass. In the upper part of the crown system the same ratio was 1–2. The variation in ratio between needle and wood biomass was whorl-specific and independent of tree class. The magnitude of the ratio was not related to the position of the tree in the stand nor to the prevailing light conditions within the state.
