|Description:||Spruce forests belonging to 5–7th groups of plants have I–Ib class of bonitet and are the most productive. Dendrological scales of spruce forests have an extension 104 years (1888–1991). Index values in the spruce forests of the 5th group plantings ranged for late wood within 0.66–1.44, for early wood – 0.61–1.30, for treering as a whole – 0.62–1.29. In spruce forests of 6th group index values fluctuated for late wood within 0.72–1.99, for ea rly – 0.63–1.26, for tree-ring as a whole – 0.67– 1.24. In spruce forests of 7th group index values fluctuated for late wood within 0.47–1.58, for early – 0.41–1.86, for treering as a whole – 0.42–1.75. Coefficients of variation of indices width of tree rings were as follows: for spruce plantations 5th group 13% for spruce 6th group – 11% for spruce 7th group – 18%, which corresponds to the lower rate of normal variation.|
