Abstract
Abstract. To characterize the effect of salt stress on six varieties of chickpea (Cicer areitenumL.): ILC 32/79, Flip 84/92C, Ghab4, Belkhadem, Collection 28 and F97/555, morphological and physiological parameters of the plants were studied to determine which can be cultivated under salty conditions. The genotypes were subjected to three increasing concentrations of NaCl (50, 75 and 100mM) and compared to an unstressed control (0mM NaCl).The results showed the studied genotypes behaved differently depending on saline concentrations, and plant water content decreased depending on NaCl concentrations, with a higher reduction in root dry matter. The root dry weight/shoot dry weight ratio decreased with high NaCl concentrations that caused reductions in root volume, number of nodules, and total nitrogen. It appeared the ILC 32/79 and collection 28 varieties were the most salinity-tolerant genotypes.
