P. Jaloviar: FINE ROOT DISTRIBUTION IN A PbRE NORWAY SPRUCH POEH-STAGE STAND Šumarski list - SUPLEMENT (2005), 229-237
CONCLUSIONS


The different stand structure caused by a different
spacing reflects on all investigated parameters. The different
fine root biomass production from the total rhizomass
production was found out, while this finding have
to be limited on the period of stand´s life, when even in
the less dense spacings the competition between the
trees in the inter-row space become to be so high, that it
comes to the more intensive drying of the lower parts of
crowns. The assumption about different way of fine root
biomass distribution was confirmed as well. The relation
between fine root density and soil depth presents
different shapes according to the spacing.


To be able to enlarge the knowledge in the forest
trees rhizology it will be necessary to focus similar studies
especially on the investigation of the issue of changes
in the fine root production of forest stands. The contribution
of this paper is also that it can be a good base
for the planning of next root systems research in the spacing
experiment Vrch Dobroc because it provides a reliable
informations about the fine root variability and basic
patterns of their distribution in the soil space.
