Elevated CO2 concentration alleviates the negative effect of vapor pressure deficit and soil drought on juvenile poplar growth

Popis výsledku v původním jazyce

The performance of short-rotation woody coppice is strongly influenced by the establishment success during the first months after planting. Future climates warmer due to elevated atmospheric CO2 (eCO2) will cause more soil and atmospheric droughts through elevated vapor pressure deficit (eVPD). Therefore, this growth chamber experiment investigated the interacting effects of eVPD, eCO2 and soil drought on the performance of juvenile hybrid poplars grown under increased air temperature. Atmospheric drought significantly affected leaf area, roots biomass, leaf net assimilation (Anet), and stomatal conductance (gs), but stem biomass only marginally. Interactions of eCO2×soil drought affected only physiological variables, whereas interactions eVPD×eCO2×soil drought only leaf area and root biomass. Soil drought and eCO2 both individually significantly affected stem and root biomass, leaf area, and Anet. The individual effect of atmospheric drought reduced the stem-, root biomass, leaf area, and proportion of roots by -9%, -20%, -21%, and -6%, soil drought by -39%, -55%, -40%, and -14%, whereas eCO2 increased them all by 24%, 47%, 14%, and 6%, respectively. Soil drought reduced Anet and gs by -76% and -84%, eVPD by -15% and -26% and eCO2 increased both by 148% and 27%. Although soil drought is likely to be a major limiting factor, atmospheric drought will not be a significant additional threat to the establishment of SRWC plantations under future conditions of climate change, at least when using genetic material with what appears to be rather anisohydric hydraulic strategy, such as the clone J-105 in the juvenile phase.
