Plants irrigated with water salinity of 0.8 dS m -1 had an average weight of 0.85 mg kg -1 while the plants irrigated with 4.0 dS m -1 obtained 0.57 mg kg -1 as a middle weight. The greatest increasing in chloride content in the grafts was observed where the content of this medium were 0.37 and 0.79 mg kg -1 , respectively, to the plants were irrigated with ECw of 0.8 dS m -1 and 4,0 dS m -1 , which afforded an increase of 53.16%. The roots and branches obtained an increase of 33% and 6, respectively. Regression analysis of the variation of chloride content in the different parts of the plant by increasing the salinity of the water irrigation and their equations are shown in Figure 1. Changes in the levels of chloride with salinity of irrigation water in the rootstocks, grafts and fitted sheets in a highly significant (p

In the case of cashew tree leaves allegedly directed sodium to the old leaves (with low metabolic activity) as reported by Shannon et al. (1994) for some species tolerant to salinity. According to Marschner (1995) would be a restriction on imports of sodium and chloride to the young leaves, which is a characteristic of salinity tolerant species. The regression analysis of the variation of sodium content in different parts of the plant by increasing the salinity of the water irrigation and their equations are shown in Figure 1. For the content of Na in roots and branches, there was a statistically significant quadratic effect (p
