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) a dense (FD) from 1998 to 2003. WUE in this study was calculated as a ratio of total aboveground biomass(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 was related to tree height increment and leaf biomass to leaf area index. TBi was found significantly higher than TBii in FD. However, WUE was notsignificantly 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, WUEii with use TBii 4.17 g/l and 4.14 g/l in FS and FD, respectively. WUE of FS and FD was similar due to identica
