Long-term Water Use Efficiency of Young Spruce Forest

Original language description

Long-term water use efficiency (WUE) describes water utilization by plants on different levels of biosphere organization. We have performed a WUE evaluation in two young spruce forests of different stand densities, sparse (FS) and dense (FD) from 1998 to2003. WUE in this study was calculated as a ratio of total aboveground biomass increment (TB) and transpiration (T) on annual time scale. Two approaches were used for total biomass evaluation: i) TBI - from stem diameter at the breast height (DBH) increment dynamic and its allometry with TB, and ii) TBII - as a sum of leaf, branch and stem biomass. Growth dynamic of branch biomass was related to tree height increment and leaf biomass to the leaf area index. TBI was found significantly higher than TBIIin FD. However, WUE was not significantly different among the stands and approaches. WUE with TBI (WUEI) used were 4.30 g/L and 4.68 g/L in FS and FD, WUE with use TBII (WUEII) 4.17 g/L and 4.14 g/L in FS and FD, respectively. WUE of FS a
