Diversity of leaf traits related to productivity in 31 Populus deltoides x Populus nigra clones Inra
Marron, N.; Villar, M.; Dreyer, E.; Delay, D.; Boudouresque, E.; Petit, J.M.; Delmotte, F.; Guehl, J.M.; Brignolas, F..
To test if some leaf parameters are predictors of productivity in a range of Populus deltoides (Bartr.) Marsh. × P. nigra L. clones, we assessed leaf traits and productivity in 2-month-old rooted cuttings from 31 clones growing in 4-l pots in a greenhouse, under conditions of controlled temperature and optimal irrigation. We evaluated four groups of variables describing (1) productivity (total biomass), (2) leaf growth (total leaf number increment and total leaf area increment rate), (3) leaf structure (specific leaf area and nitrogen and carboncontents) and (4) carbon isotope discrimination (∆), which is negatively correlated with time-integrated water-use efficiency. High-yielding clones did not necessarily display high leaf growth rates, but they...

Effects of environment and progeny on biomass estimations of five hybrid poplar families grown at three contrasting sites across Europe Inra
Dillen, S.Y.; Marron, N.; Bastien, C.; Ricciotti, L.; Salani, F.; Sabatti, M.; Pinel, M.P.C.; Pinel, A.M.; Taylor, G.; Ceulemans, R..
The quantitative and qualitative estimation of aboveground previous termbiomassnext term production is essential for short-rotation forestry. Indirect methods of previous termbiomassnext term estimation have been developed based on the establishment of regressions between previous termbiomassnext term components and tree dimensions as well as canopy architecture. The difficulty encountered with this method is to know whether, and to what degree, the obtained equations can be used under contrasting environmental conditions and for different genetic backgrounds. In the present study, allometric equations were developed linking tree dry weight (stem, branch and aboveground tree dry weight) with stem circumference, stem height and number of sylleptic branches...

Genomic regions involved in productivity of two specific poplar families in Europe. 2. Biomass production and its relationships with tree architecture and phenology Inra
Marron, N.; Storme, V.; Dillen, S.Y.; Bastien, C.; Ricciotti, L.; Salani, F.; Sabatti, M.; Rae, A.M.; Ceulemans, R.; Boerjan, W..
Short-rotation coppice of hybrid poplar is a promising renewable feedstock for biofuel production. Breeding for high biomass in short-rotation coppice has started only recently. Two hybrid poplar families were grown at two sites in Europe and phenotyped for a variety of biomass-related traits (1) to examine the extent of phenotypic and genetic variation in biomass production, ramification, resprouting, and phenology, (2) to search for genomic regions involved in productivity, and (3) to determine the effect of the environment on the expression of these traits. The performance of both families differed within and among sites. A pronounced heterosis was observed in most cases. Moderate to high heritability values were found. Seventeen quantitative trait loci...

Modulation of leaf physiology by age and in response to abiotic constraints in young cuttings of two Populus deltoides x P. nigra genotypes Inra
Marron, N.; Brignolas, F.; Delmotte, F.; Dreyer, E..
•Pour comparer de manière fiable la réponse physiologique de feuilles de différents génotypes aux contraintes abiotiques, il est important de prendre en compte les effets liés à la position et à l’âge des feuilles au sein de la canopée pouvant interférer avec la réponse à la contrainte. •Afin de documenter de tels effets, les capacités photosynthétiques et la tolérance à la chaleur et aux oxydations ont été mesurées sur des feuilles réparties tout le long de la tige de boutures de 3 mois des génotypes de Populus deltoides × P. nigra, ‘Luisa_Avanzo’ et ‘Dorskamp’. •Tous les traits mesurés présentaient une forte variabilité liée à l’âge des feuilles. Les capacités photosynthétiques augmentaient graduellement durant l’expansion foliaire, en parallèle avec les...

Plasticity of growth and sylleptic branchiness in two poplar families grown at three sites across Europe Inra
Marron, N.; Bastien, C.; Sabatti, M.; Taylor, G.; Ceulemans, R..
Two hybrid poplar maternal half-sib families, resulting from controlled crosses of the female parent Populus deltoides ‘S9-2’ with P. nigra ‘Ghoy’ and P. trichocarpa ‘V24’, were grown at three sites: northern Italy, central France and southern England. Juvenile stem growth traits (height, circumferenceand volume) and sylleptic branchiness (number of branches, density of branches per unit of stem height, percentage of the stem carrying branches and distance of the highest sylleptic branch to the top of the stem) were measured on 1-year-old shoots. Our general objectives were to determine the degree to which the expression of stem growth and syllepsis and the relationships between them are affected by environmental conditions and to evaluate the efficiency...

Variability in Populus leaf anatomy and morphology in relation to canopy position, biomass production, and varietal taxon Inra
Al Afas, N.; Marron, N.; Ceulemans, R..
Douze génotypes de peuplier (Populus), appartenant à différents taxa ainsi qu’aux sections Aigeiros et Tacamahaca, ont été étudiés durant la troisième saison de croissance de la deuxième rotation d’une plantation à forte densité. L’objectif de l’expérience était demettre en évidence les relations entre les caractères foliaires, la production de biomasse et le taxon, ainsi que l’influence de la position des feuilles dans la canopée. Pour ce faire, diverses caractéristiques anatomiques et morphologiques des feuilles (épaisseur des épidermes et des parenchymes palissadique et lacuneux, densité et longueur des stomates, surface foliaire, surface foliaire spécifique (SLA) et teneurs en azote) ont été déterminées pour des feuilles matures de tous les génotypes...
