Abstract
The experiment was conducted to validate the effect of salinity (NaCl) and seed priming (CaCl2) on biological yield of wheat. The six wheat varieties (Lalma-13, Pirsabak-05, Atta-Habib-10, Pirsabak-08, Inqilab-91 and Saleem-00) were tested at two seed treatments (un-primed and Primed with 50 mM CaCl2) and four salinity regimes (0, 3, 6 and 9 dSm-1) in soil culture. The seed priming and salinity has significantly (p≤0.05) affected physiological, biochemical parameters and biological yield of wheat varieties. Wheat variety (Pirsabak-05) was tolerant in saline environment in term of producing highest shoot chlorophyll a and b content (1.60 and1.03 mg g-1 fresh weight), shoot proline content (118.20 μg g-1 fresh weight), shoot K+ content (1.23 mg g-1 dry weight), shoot and root Ca++ content (0.76 and 0.58 mg g-1 dry weight), biological yield (12.46 g plant-1), and lowest shoot Na+ (1.11 mg g-1 dry weight) & Na+/K+ ratio (1.03).Saleem-00 and Inqilab-91 varieties were highest accumulator of shoot Na+ (1.26 mg g-1 dry weight) and Na+/K+ ratio(1.55) respectively. Experimental findings suggested that except shoot Na+ and Na+/K+ ratio, all biochemical, physiological parameters and biological yield of wheat varieties could be enhanced with seed priming. The salt tolerant wheat varieties (i.e. Pirsabak-05 and Lalma-13) were more responsive to seed priming than salt sensitive varieties (i.e. Inqilab-91 and Saleem-00).
