Photosynthetic Behavior of Argania spinosa (L.) Skeels Induced under Grazed and Ungrazed Conditions

The endemic Moroccan species Argania spinosa is considered the most grazed tree in its distribution area. Since grazing exerts an important effect on plant performances, we attempted to explore impact of A. spinosa. Thus, performed a comparative field experiment where seasonal variations gas exchange, photochemical efficiency, relative water content, photosynthetic pigment and stomatal features were assessed ungrazed trees. net rate was increased trees spring autumn, favorable seasons. Enhancement performance may be due high conductance registered This mechanism compensate for lost leaf area, order recover from stress. In addition, exhibit better use more economically show lower oxidative However, results obtained summer that compensation could limited by drought. key preserving future forests sustainable forest management, our suggest proper management can control tool increase improve resilience.
