One of the important effects of salinity in plants can be noted in growth trend and the process of changes in the activity of the enzyme system and their antioxidant properties. In this research, the effects of salinity stress on the enzyme system and their antioxidant properties of almond (Shahrood 12) on some of the prunus rootstocks (Bitter Almond, Tetra, GF677, GN15) and non-grafted rootstocks under salt stress in a factorial experiment based on a completely randomized design with Two factors including 8 scion-rootstock compositions and five levels of irrigation water salinity were performed in three replications. The results showed that different levels of salinity significantly reduced the number of leaves in the main branch, as well as the total number of leaf in rootstocks, the diameter and height of the scion, and the fresh weight of the aria parts. The highest total antioxidant activity was observed in Shahrood 12 on GF677, at a salinity level of 8dS m-1, with a rate of 30.97%, which had a significant difference with other graft compounds and without graft rootstocks. The lowest total antioxidant activity was observed in the combination of Shahrood 12 on the Tetra rootstock at 10.1%. The antioxidant capacity, soluble sugars, activity of catalase enzymes, ascorbate peroxidase in all studied graft compounds and without graft rootstocks increased with increasing salt concentration, and then, with increasing salinity levels, the amount of them decreased. In general, based on the results, it can be concluded that among the linkages and bases studied, the Shahrood 12 cultivar grafted on the GF677 rootstock and on the almond seedling was the most tolerant compound and susceptible to the salt stress respectively.
