Kurzfassung:
Undomesticated plant species may be a valuable resource for increasing crop diversity and developing crops for use in semiarid and saline areas. Australian channel millet ( Echinochloa turnerana (Domin) J. M. Black) is very drought tolerant; however, its salt tolerance has not been tested. In drum culture studies, conducted in the greenhouse, plant height, weight, and seed grain weight were measured as a function of saline stress. Concentrations of Na, Ca, and Cl in leaves and stems increased as soil salinity increased. At salinities above 1.5 S m −1 , E. turnerana is as salt tolerant as bermudagrass ( Cynodon dactylon L.). The grain yield by E. turnerana was decreased by 50% by 2.4 S m −1 salinity; whereas, previous studies have shown that proportionate grain yield reductions of sorghum [ Sorghum bicolor (L.) Moench] and barley ( Hordeum vulgare L.) occur at 1.1 and 1.8 S m −1 , respectively. E. Turnerana has high salt tolerance as either a grain or forage crop, and as a forage displays superior digestibility. This species could be exploited for future use on marginal lands.
