Key messageMixing sessile oak and Scots pine in central France to reduce intraspecific competition for water resources did not improve the ability of these two species to withstand severe drought during the summer.ContextIn order to reduce the impact of increasingly extreme droughts on forests, managers must adapt their practices to future climate ...

Aims: The aim of this study is to test a method to extrapolate vine water status (estimated by the water potential; Psi) over a whole appellation (protected geographical indication). The spatial extrapolation is based on an empirical approach that combines a reference site (baseline measurements) and carbon isotope discrimination (delta C-13) value...

The ongoing global change could be an additional threat to the establishment and the long-term survival of Populus nigra L., an emblematic European riparian species. With the general aim of gaining insights into the adaptive potential of this species, we (i) quantified variations within and among three French P. nigra populations for key physiologi...

Climatic events predicted for this century should involve drier and warmer summers, such as those that occurred in 2003 and 2005 in France. The higher temperatures could become a limiting factor for the regeneration of Populus nigra L. species. During establishment and development in summer period, seedlings must be able to resist high temperatures...

We present results and insights gained from the characterization of the hydraulic architecture of eight field-grown Populus deltoides × Populus nigra genotypes, already known to differ in terms of growth performance, water-use and xylem anatomy (Marron et al. 2005, Monclus et al. 2005, 2006; Fichot et al. 2009). Under well-watered conditions, we pr...

We examined the relationships between xylem resistance to cavitation and 16 structural and functional traits across eight unrelated Populus deltoides x Populus nigra genotypes grown under two contrasting water regimes. The xylem water potential inducing 50% loss of hydraulic conductance (Psi(50)) varied from -1.60 to -2.40 MPa. Drought-acclimated t...

Six Populus deltoides Bartr. ex Marsh. x P. nigra L. genotypes were selected to investigate whether stem xylem anatomy correlated with gas exchange rates, water-use efficiency (WUE) and growth performance. Clonal copies of the genotypes were grown in a two-plot common garden test under contrasting water regimes, with one plot maintained irrigated a...

Genotypic variability for productivity, water-use efficiency and leaf traits in 33 genotypes selected from an F1 progeny of Populus deltoides Bartr. ex Marsh x Populus trichocarpa L. was explored under optimal and moderate water-deficit conditions. Saplings of the 33 genotypes were grown in a two-plot open field at INRA Orléans (France) and coppice...

Genetic variation of leaf proteome in drought response was investigated among eight Populus xeuramericana genotypes contrasting for their leaf carbon isotope discrimination (Delta), an estimate of intrinsic water-use efficiency. Plants were grown in open field on two similar plots. Drought was induced by an 86-day irrigation cessation on one plot, ...
