Correlations between needle and shoot growth characteristics in Scots pine (Pinus sylvestris L.) stands
Department of Ecology and Environmental Research, Swedish University of Agricultural Sciences S-750 07 Uppsala Sweden
Shoot, needle and bud growth in three stands of different ages (9, 20, and 60 years) of Scots pine were studied in order to reveal relations between these variables. Within the growing season the sizes of buds and needles developed in parallel. Significant regressions between number of short shoots and either average needle length or total needle length of the parent shoot were found. The strongest regressions were found in the two youngest stands as well as in the top of the canopy.
