Abstract: | • Introduction The objective of this work was to study how spacing and genetic entry and/or origin group affect radial growth (ring width
and cumulative diameter development) and ring density from pith to bark in Scots pine (Pinus sylvestris L.) and in what sense their annual variability could be explained by the climatic variables. The spacing trial was located
in central Finland, with current stand density range of 2,000–4,000 trees per hectare. All the six genetic entries had Kanerva
pine (plus tree S1101) as a father tree, whereas the mother tree represented Finnish plus trees from southern, central and
northern Finland. |
