ON THE HEIGHT GROWTH RATE OF BLACK ALDER UP TO ITS 20-YEAR AGE


Summary


Investigations were carried out in the Forest district of Đurđevac (the Drava
River Basin, Croatia), in the forest management unit of »Preložničiki Berek — Lepa
Greda«, compartment 41e, in a 20-year-old stand. This type of the forest represents
a geographical variant of the association Pruno-Fraxinetum Ob. 1953. The type of
soil is a brownized gley. The height increment was investigated on 5 dominant trees
of seedling origin, and on 5 dominant coppice trees. The curves of the total increment
for the trees of seedling origin are represented in Graph 1. The current and
mean annual increments for the trees of seedling origin are represented in Graph 2,
and for the copice trees in Graph 3. The numerical data are shown in Table 1. Finally
the author draws attention to the importance of knowing these phenomena as the
elements for the determination of the kind and time of the tending measures to be
applied in the stands of Black Alder.
