Abstract
Potted experiment was conducted on transplants of five olive cultivars ”Picual, Hamed, arbiquena, Kalamata and Toffahi” besides four F1 hybrids ”H61, H138, H107 and H69”to investigate the impact of salinity (6000 and 9000 ppm and SAR-12) and possibility of alleviating salts hazarda through application of some recovering substances (magnetite, potassium silicate and kitasal). Results showed that, survival (%) and vegettive growth parameters (stem length and diameter, laterals&leaves numbers/ plant, leaf area, assimilation area/ plant and fresh and dry weight) were significantly varied depending on the studied salinity level, wherease; all parameters were significantly decreased as salt concentration increased. The physiological parameters revealed two confilected trends, whereas ossmotic potential was increased by salinity, but the reverse was found with transpiration rate. The chemical composition (leaf chlorophyll A and B, carotenoids, Cl, Na, K, Ca, N, P, total soluble sugars and proline) contents, showed two opposite trends i.e., (Cl, Na, Ca, total soluble sugars and proline) increased by salinity, while, the reverse was detected with (chlorophyll A amd B, carotenoids, K, N and P)
