Effect of NaCl Pretreatment on the Germination and Emergence of Seven Cultivars of Wheat Seeds
Mohammad Ashraf , Nasim Akhtar , Firdous Tahira and Faiz-ul-Hassan Nasim

Abstract:
Seeds of seven different cultivars of wheat (Triticum aestivum) were pre-imbibed in water or in 5, 10, 20% NaCl solutions for 2 days at room temperature. The effects of these pre-treatments on the percentage seed germination, seedling emergence and spread of emergence were observed. All viable seeds germinated within 48 hours under laboratory conditions. However. in pot experiments, first seedling emergence was recorded after 150 hours (6.25 days). Seed germination tests carried out in the laboratory reflected profiles similar to that in pot experiments. Water pre-treatment had no effect on the percentage seed emergence in pot experiments but decreased the spread of seedling emergence compared with that of control. NaCl treatment at 5 percent concentration had no effect on seedling emergence in pot experiments, less seeds germinated and emerged in 10 percent NaCl treatments compared with the 20 percent NaCl treatment or control seeds. Some cultivars were found to be less resistant to salt treatments than the others.
