Experimental factors included salinity (0, 4, 6 and 8 dS/m) and level of chitosan (0, 0.1, 0.2%, all dissolved in 1% acetic acid) along with an additional treatment of distilled water. Results indicated that with increasing salinity malondialdehyde content (0.834 mM g-1), proline (0.254 mg.g-1 FW), total carbohydrate (10.48 mg.g-1 FW), Na+ concentration of shoot (1.87%), Na+ concentration of root (2.05%) were increased while other traits under study were decreased. Chitosan treatment increased shoot height, shoot dry weight and relative water content and decreased malondialdehyde content. Under salinity conditions, chitosan treatment root height, root dry weight, proline and total carbohydrate were increased. Also, chitosan increased K+ concentration and decreased Na+ concentration of shoot under both unstressed and stressed condition. In plants treated with chitosan, K+ concentration of root increased compared with control plants, but the Na+ concentration of root decreased by 7.14 %. The results of the study indicate that priming the chickpea seeds with chitosan reduce the harmful effects of salinity via either reduction in Na+ absorption or by accumulation of proline, total carbohydrate and K+.
