Summary

The modifying effect of calcium (Ca) on the salinity tolerance of Wimmera ryegrass during germination and early seedling growth was studied. Pretreatment of seeds with Ca has no significant effect on germination under NaCl or MgCl2 salinity. The addition of Ca to the germination medium increased the germination percentage significantly, especially with MgCl2. Significant increases in seedling shoot and root growth also occurred with Ca addition to the growth medium under MgCl2 salinity.
