Abstract: The objective of this work is to determine the morpho-biochemical behavior of olive (2 years old) plants stemming from herbaceous cuttings and grafted on an oleaster, with two varieties of Spanish origin (Manzanilla and Arbiquina) and two varieties of Algerian origin (Sigoise and Chemlal) under the effect of irrigation with salin water at 100 mM-l-1 NaCl. The experimentation takes place in the Faculty of Science of Nature and Life - Tiaret Ibn Khaldoun - University - Algeria, under a semi-automatic greenhouse and under well controlled conditions. The control plants are irrigated with a nutrient solution, while the plant stress received nutrient solution enriched by sodium chlorure in four repetitions 100 mM / l NaCl. The analysis focused on the measurement of leaf area, soluble sugar and proline content. According to the results obtained, the leaf area of the treated plants slightly decreased compared to that of the control plants. However, the 20 weeks of brackish irrigation resulted in proline and sugars accumulation in the stressed genotype compared to the control genotype. In addition, this accumulation is very important for the leaves of plants local origin (Algerian) compared to introduced plants (Spanish) and in the leaves of plants grafted on oleaster compared to plants from herbaceous cuttings.
