Characteristics of the increment of spruce trees in the period from 32 to 50 years after the application of two heavy selective thinnings
Апстракт
The paper presents the characteristics of the increment of tree growth elements (height,
diameter, basal area and volume) in the monoculture of the spruce (Picea abies Karst.) in the
period of 33-40 and 41-50 years, after the application of heavy selective thinnings. In both
periods, the trees with larger dimensions, i.e., breast height diameter, had greater increments
of growth elements compared to the smaller trees. By grouping trees in the group of 200 trees
per hectare sorted by their diameters showed that after the first thinning the 600 thickest trees
per hectare had uniform increments of diameter at breast height, basal area and volume being
significantly larger than the next group of thinner trees. In the period after the second
thinning, the groups of the 200 thickest trees per hectare had significantly higher increments
of diameter, basal area and volume in relation to the next groups of 201 to 600 thickest trees
that had a uniform and significantly greater incremen...ts from the following groups of the
thinner trees. The results indicate that in the studied spruce plantation only 600 thickest trees
per hectare singled out according to the size of the increment in the period after the first
thinning. In the period after the second thinning, only the 200 thickest trees were singled out
according to the size of the increment in diameter at breast height, basal area and volume,
which indicates to intensive differentiation of trees according to the increment potential under
the influence of heavy selective thinning.
