Formatted Abstract/Summary
We have assembled a large collection of over 1000 naturalised Australian bermudagrasses (Cynodon spp.). Our previous research indicated that a group of the grasses collected from Australian Mediterranean environments were drought resistant and characterized by large rhizomes that could be a potential source of nutrients, water and carbohydrates when these grasses grow under saline conditions. The objective of this research was to test the salinity tolerance of 12 bermudagrass genotypes with different levels of drought resistance using a flood and drain sand solution culture. Eight salt treatments were imposed ranging from 1.3 to 21 dS/M (0 to 175 mM NaCl). There was no correlation between drought resistance and salt tolerance (r = 0.21~0.37ns) although some drought resistant grasses did have excellent salt tolerance. The grass with the best salt tolerance was not highly rhizomatous. At 21 dS/m some grasses maintained over 60% total biomass, relative to the control treatment, and can be considered as highly salt tolerant. Based on these results we are currently screening about 70 genotypes collected from salt scalds, maritime environments, and saline/sodic soils.
