Abstract
A laboratory experiment was conducted to investigate salt tolerant sorghum genotypes based on morphological characters of nine sorghum genotypes during germination and seedling growth. The treatments were consisted of 0mM and 100mM NaCl and nine genotypes were BD 686, BD 687, BD 693, BD 699, BD 700, BD 747, BD 748, BD 750, BD 753. The experiment was laid out in a CRD with 3 replications. The plants were grown hydroponically in the plant physiology laboratory, Department of Crop Botany, BAU, Mymensingh. Under salinity stressed (0 and 100 mMNaCl) condition, tolerant genotypes BD 750 and BD 686 showed higher germination percentage, different stress tolerance index (GSTI, SLSI, RLSI,FSTI and DSTI), shoot and root length, fresh weight , dry weight, leaf area (LA), vigor index than those in sensitive genotype BD 747 and BD 753. The underlying mechanism to these changes was described in details.
