Allometric relationships for dry mass of aboveground organs estimation in young highland Norway spruce stand

Popis výsledku v původním jazyce

This study falls into site-specific studies (here in the Drahanská vrchovina Highland) focusing on the determination of allometric relationships between the stem dendrometric and biomass parameters in young Norway spruce stands. The total aboveground biomass (TB) of a sampled tree with 14.9 m in height and 15.5 cm in stem diameter at 1.3 m (DBH) averaged to 110.3 kg. The stem biomass participated on average by 54 %, branch biomass by 24 % and needle biomass by 22 % on the TB of the sampled spruce tree.TB of the tree and the biomass of individual aboveground tree organs were predicted with the highest accuracy (over 91 %) from DBH or a stem diameter at the one tenth of the tree height using allometric-power functions. The stem diameters up to 70 % of the relative tree height predicted TB accurately (over 95 %) as well. The biomass expansion factors based on the stem volume expansion to TB of the tree, as well as the biomass of each of the aboveground tree organs did not show functional
