Abstract
The objective of this work is to determine the effect of salinity on the morphophysiological behavior of young olive plants in cuttings and grafted plants, including
two local varieties (Chemlal and Sigoise) and two introduced varieties (Manzanilla and
Arbiquina). The experiment took place in a greenhouse with a well-controlled
condition. The experimental plan is in a complete randomization of two factors (salinity
and varieties); plants without NaCl application were used as control. The plant material
(young 2-year-old olive seedlings) was selected and brought from a crop nursery. The
experimentation started by the irrigation of the control plant with a nutrient solution.
About the salinity treatment, the tree seedlings received a nutrient solution fortified by
the addition of 100mM of NaCl. Four repetitions are being done according to the field
capacity. The study covered the variation of the relative water content in leaves as well
as the leaf surface, stomata density, stomatal size and the wax rate on the upper foliar
epidermis. RWC leaf area and stomatal density of the treated plants decreased
compared to the control. On the other hand, the wax level increases in the case of salt
stress compared to the control, both for the grafted plants and for the plants not grafted.
