1. Prévision de la variabilité intra- et interarbre de la densité du bois de chêne rouvre (Quercus petraea Liebl) par modélisation des largeurs et des densités des bois initial et final en fonction de l'âge cambial, de la largeur de cerne et du niveau dans l'arbre

R Degron, G Nepveu,

Predicting intra- and intertree variability of wood density in sessile oak (Quercus petraea Liebl) through modelling earlywood and latewood width and density from cambial age, ring width and height in...

4. Characterization of transcript isoform variations in human and chimpanzee

Benovoy, David,

Transcript expression and pre-mRNA processing are emerging as important mechanisms that increase the complexity of eukaryotic transcriptomes. These processes allow a genomic locus to produce a number ...

8. Interpreting the variations in xylem sap flux density within the trunk of maritime pine (Pinus pinaster Ait.): application of a model for calculating water flows at tree and stand levels

Denis Loustau, Jean-Christophe Domec, Alexandre Bosc,

Sap flux density was measured throughout a whole growing season at different locations within a 25-year-old maritime pine trunk using a continuous constant-power heating method with the aim of 1) asse...
