Is allometry for aboveground organ’s mass estimation in young Norway spruce stands affected by different type of thinning?
The study focuses on determination of aboveground organ’s mass using allometric relationships in Norway spruce stands with different type of thinning management – thinning from below (TfB) and thinning from above (TfA). Allometric functions for predicting of stem, branch, leaf and total aboveground...

| description | The study focuses on determination of aboveground organ’s mass using allometric relationships in Norway spruce stands with different type of thinning management – thinning from below (TfB) and thinning from above (TfA). Allometric functions for predicting of stem, branch, leaf and total aboveground mass were estimated from measurements of basic stem dendrometric parameters. The highest adjusted regression coefficients were found between DBH and biomass of aboveground tree organs (adj. r2 ranged from 0.91 to 0.98). Multiple linear regressions provide correlation coefficients r2 from 0.88 to 0.98 for TfB and from 0.90 to 0.98 for TfA. The presented results showed no effect of different type of thinning application on tree allometry. |
