Evaluation of salt stress tolerance of chilli (Capsicum annuum L.) genotypes at seedling stage
Salinity is increasing problem and is one of the main threats to crop productivity worldwide. Understanding the adverse impact of salt stress (NaCl) at early growth stages is essential for evaluation of salt stress tolerance in plants.

Understanding the adverse impact of salt stress (NaCl) at early growth stages is essential for evaluation of salt stress tolerance in plants. A trial was performed during 2017 following completely randomized design (CRD) factorial with three replicates. Three chilli genotypes varieties were received 5 salt stress levels. The canal irigation water having Electrical conductivity (EC) of 0.5 dSm-1 was kept as control. The Salinity levels included 1, 3, 5 and 7 dS m-1, respectively. It was noted that all the studied traits were considerably influenced by salinity (P0.05) for germination, leaves plant-1 and seedling vigour index and significant (P |
