Abstract
In this study, we investigated the interaction effects of salinity (NaCl) and CaCl2 on olive trees. The experiment was conducted with three levels of NaCl (0, 40 and 80 mg LE¹) and four levels of Ca2+ (0, 50, 100 and 150 mg LE¹). The effects of NaCl and CaCl2 on the growth and ion concentrations in olive (Olea europaea cv. Manzanillo) were investigated. The results showed that the annual and accumulated yield, fruit size and vegetative growth ratio were affected by salts. Shoot length was higher in plants treated with CaCl2, although shoot growth was reduced at 50 mg L-1 NaCl. The NaCl concentrations in plants were also affected by the Ca2+, K+ and N concentration. Ca2+ supply linearly increased leaf Ca2+ concentration and decreased leaf Na+ concentration. Leaf Ca2+, K+, and N decreased under salt stress. The results obtained from this experiment showed that salt stress caused a significant reduction in plant growth and leaf number and weight. Therefore, the high-Ca tolerance index for yield was effective in screening for high fruit number and high yield of olive, and the high-salinity tolerance caused to decrease for olive yield. The effect of CaCl2 and salinity was significant the yield and growth of olive plants.
