Le-premier-groupe, g max définie pour VPD<1.5kPa), significativement plus faibles pour de faibles VPD mais aussi sur l'ensemble de la gamme de VPD utilisée, par rapport aux génotypes constituant le deuxième groupeTableau 1) La diminution de g s en réponse au VPD était plus forte pour les génotypes du groupe 2 que pour ceux du premier groupe (courbes non parallèles, Figure 1a) Il semblerait donc qu'il existe une variabilité de réponse des stomates au VPD pour les sept génotypes de cette étude, comme l'ont montré les travaux de Brendel, et 214) présentaient des conductances stomatiques Picea glauca x P. engelmannii, pp.173-348, 1998.

Vpd-pour-laquelle-g-s-est-nulle, La plupart des génotypes de cette étude présentait une valeur de e g1/m proche de 5kPa (Tableau 1), ce qui correspond à la valeur trouvée par Brendel et al. (2008) sur cette même famille de chêne pédonculé, mais aussi à la gamme observée par Oren et al. (1999) pour différentes espèces du genre Quercus (entre 3 et 6kPa) Excepté le génotype 118 pour lequel e g1/m est très élevé, aucune différence entre génotypes de ce trait n'a été mise en évidence (Tableau 1). Cependant, ces valeurs e g1/m sont approximatives, puisque nous n'avons pas de données au-delà de 3kPa pour les confirmer. Il semblerait d'ailleurs que l'ajustement logarithmique ne soit pas toujours adapté à nos données. Cette observation prévaut principalement pour les génotypes du groupe 2 (fort g max ) pour lesquels g s, Les courbes de réponse de g s au VPD ont ensuite été standardisées entre 0
