The present study was conducted to assess the impact of nitrogen treatment on the physiological aspects of cork oak (Quercus suber L.) seedlings from acorns collected from seven sources (Kroumiry and Cap-bon). Nitrogen fertilization increased significantly specific leaf area (SLA) and leaf mass area (LMA) of Q. suber L grown for 2 months at nitrogen concentration 1.5 g/l, respectively. Results indicate that leaf hydraulic conductance (KLeaf) increased significantly under nitrogen treatment, but no significant correlation was observed between KLeaf, A and gs. Stomatal conductance (gs), transpiration rate (E), net photosynthetic rate (A) and maximum efficiency of PSII (Fv/Fm) were investigated in seedlings of Q. suber L. This study validated that KLeaf, the stomatal conductance, transpiration rate and net photosynthetic rate of Q. suber were performed under .. View More»
