Changes in certain organic metabolites during seedling growth of chickpea under salt stress and alongwith exogenous proline

Salt tolerant (BG-372, KWR-108) and susceptible (C-235, H-208) chickpea genotypes were subjected to varied levels of salt stress (0.0, 4.0, 8.0 and 12.0 dS/m) to investigate certain biochemical parameters in 8-day old seedling under different level of salt stress alone and alongwith exogenous proline of 10⁻⁵M concentration. The salt stress decreased the total sugar, reducing and non-reducing sugar but increased starch, and proline content. The exogenous proline when applied with saIt stress reduced the adverse effect of salt stress. Lower soluble protein content was noticed in tolerant genotypes.
