Abstract in another language

Climate models predict increasing frequency and intensity of summer drought events for Central Europe.In a field experiment, we investigated the response of young beech (Fagus sylvatica L.) to extreme andrepeated summer drought and the modulation of drought response patterns along the natural gradientof light availability at the study site. In autumn 2008, two-year-old, nursery derived beech – as usedfor forest conversion practices – was planted under a Norway spruce stand primarily opened throughwinter storm. Precipitation was manipulated in the growing seasons of 2009 through 2011, inducing apronounced gradient of water availability. Individual drought-stress doses (DSD) and light doses (LD)were calculated for each beech sapling during the three growing seasons. Plant growth, CO2-assimilationrate and stomatal conductance were reduced with increasing drought stress, but facilitated by increasinglight availability. Progressive acclimation to water and light limitation during the three years of theexperiment led to a decreased drought and shade sensitivity of diameter growth. Water-use efficiency,root/shoot ratio and rooting depth, were increased with decreasing water availability. Mean fine rootdiameter and specific fine root length correlated positively with both DSD and LD. Proceeding low-lightacclimation was indicated by progressively increasing specific leaf area and reduced leaf dark-respiration.Present results suggest that nursery-induced high-light acclimation of the beech saplings, exacerbatedlight limitation upon transplant and hence productivity decline under co-occurring water limitation.
