Abstract
A greenhouse experiment was conducted to study the effects of sodium chloride (NaCl) on growth, nutrient status, carbohydrate and proline content and gas exchange parameters of pomegranate plants (Punica granatum L.) cv. Wonderful. One-year-old own-rooted pomegranate plants were grown for 58 days in a 1:1 sand–perlite medium. They were irrigated with nutrient solutions containing two concentrations of B (25 or 100 μΜ) in combination with 0, 40 or 80 mM NaCl and 1.0 or 10 mM CaCl2, respectively. At the end of the experiment, the greatest height was observed in plants treated with 1.0 or 10 mM CaCl or 100 μM B, whereas it was significantly reduced by the inclusion of NaCl into the nutrient solution. Similarly, a decline of fresh and dry matter weight was recorded in the treatment with 80 mM NaCl. The concentration of chlorophyll and carbohydrates in leaves was unaffected by the inclusion of NaCl into the nutrient solution, whereas in roots, the respective concentrations of carbohydrates were reduced by 50% compared to control. Moreover, as a result of salinity (mainly 80 mM NaCl), a decrease of photosynthetic parameters (photosynthetic rate and stomatal conductance) was recorded, while proline concentration of leaves increased and that of roots was reduced. Finally, the inclusion of NaCl in the nutrient solution led to increased Na and Cl, reduced P and Mg in leaves, and P, K and Zn in roots. However, B, Fe and Mn concentrations were not affected by NaCl treatments
