Effect of Sea-salt Stress on Germination of Tall Fescue and Italian Ryegrass

YU Hui, SHEN Yi-xin (College of Animal Science and Technology, Nanjing Agricultural University, Nanjing 210095, China)  
Germination response of tall fescue (Festuca arundinacea cv. Fawn) and Italian ryegrass (Lolium multiflorum cv .Barspectra) treated with sea-salt solutions were studied. The results showed that irrigation with sea-salt solution lower than 6.4 g/L had no effects on germination of both species. With salinity increasing, germination rate and seed vigor index decreased gradually. The sea-salt tolerance of Italian ryegrass during germination period was higher than that of tall fescue. Sea-salt concentration causing 50% germination rate decrease in tall fescue and Italian ryegrass were 19.98 (g/L) and 22.78 g/L, respectively.
