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. |
