Seeds of a Kentucky bluegrass cultivar (Poa pratensis 'SD Common') and two native buffalograss (Buchloe dactyloides) strains, Texas (TX) selection and North Dakota (ND) selection, were tested for their germination tolerance to increasing levels of NaCl at 0, 0.05, 0.1, 0.2, 0.4, 0.6, 0.8, 1.2, 1.6, 2.0, 2.4, 2.8, 3.2% in solution. Both the TX and ND strains of buffalograss exhibited a high degree of salt tolerance with the upper limit of seed germination at 2.8% NaCl (2% to 7% germination after 6 days). At high NaCl concentrations, however, percent seed germination was much greater in the ND strain than the TX strain of buffalograss. For instance, seed germination at 0.8% NaCl was 90% in ND strain and 53% in TX strain as compared to the control. Kentucky bluegrass was least tolerant to NaCl with the upper limit of seed germination at 0.4% NaCl (14.7% germination in 6 days). Seed germination in Kentucky bluegrass was completely inhibited at 0.6% NaCl.
