Drought responses, hydraulic acclimation and embolism repair potential were investigated in European beech and Norway spruce trees. In adult trees subjected to through-fall exclusion over two years, acclimation of branch and leaf hydraulic traits was found in both species. In drought-irrigation cycles in potted saplings, embolism dynamics were related to stem non-structural carbohydrate content: only spruce recovered stem hydraulic function upon drought stress relief, which was connected to carbohydrate depletion.
