AB <p>Salinity is a serious abiotic stress, causing oxidative stress. Various biochemical parameters in chickpea genotypes were considered under varied NaCl concentrations (0, 8 and<a id="OLE_LINK15" name="OLE_LINK15"></a><a id="OLE_LINK16" name="OLE_LINK16"></a>&nbsp;12 dS.m-1<span dir="rtl">&nbsp;</span><span dir="rtl">(</span><span dir="ltr">&nbsp;</span>. This experiment was done as factorial arrangement (genotype &times; salt concentration &times; time) in a completely randomized design. Samples were&nbsp;<a id="OLE_LINK3" name="OLE_LINK3"></a><a id="OLE_LINK4" name="OLE_LINK4"></a>collected at 21 and 28-day old seedlings (28-DOS). The results revealed that increasing salt concentration resulted in higher levels for malondialdehyde content; among genotypes,&nbsp;<a id="OLE_LINK25" name="OLE_LINK25"></a>MCC806&nbsp;with 2.2 and MCC760 with 0.7 had the highest and lowest amount, respectively.

The leaf soluble carbohydrates also increased significantly in MCC544 and MCC760 compared with the others. The minimum decline of electrolyte leakages (6%) was belonged to MCC760 while MCC806 genotypes showed the highest decrease rate (more than 20%). Total leaf chlorophyll content decreased in all genotypes during the stress. However, morphological damages in MCC544 and MCC760 genotypes were less in 28-DOS at 8 and 12 dS.m-1 NaCl, respectively. Overall, proline and leaf soluble carbohydrates were more consistent with salt tolerance responses of the genotypes, and 2 weeks after stress initiation (28-DOS) could be a critical stage for screening the genotypes.</p>
