Laboratory Studies on the Effects of Different Salt Concentration on Seed Germination

Salinity is the most severe concern to crop production worldwide causing huge losses to cultivated crops. A laboratory study was carried out to test the effects of salt on seed germination, root and shoot length of rice, black gram and cotton. It was observed that salt concentrations had negative effect on seed germination, root and shoot ratio. Increasing in salt concentration generally caused a progressive retardation in seed germination. As the concentration increased or at higher level, the germination percentage and other parameters were also drastically reduced. Under higher concentrations these plants were died before they were able to grow, bear root and shoot in all three crops.
