Dependence of the morphometric indices of Picea abies needles on the coenotic rank of the tree


, : Dependence of the morphometric indices of Picea abies needles on the coenotic rank of the tree. Lesovodstvo, Lesnye Kul' tury i Pochvovedenie: 47-51

Needles were sampled from trees of 15 different coenotic ranks in an uneven-aged spruce stand. Trees of rank 1 had the greatest values of ht, d.b.h., age, crown diam., crown length, and total aerial weight. The 100-needle weight and needle length were determined for upper, mid and lower crown for the trees of the different ranks. The results are plotted in graphs, and show that the morphometric indices of the needles depend on the light and on the coenotic rank of the trees.
