Abstract: | Alfalfa and subterranean clover plants were grown in highly purified nutrient solutions to which selenite selenium had been added at 0, 0.025, 0.25, 2.5 or 25.0 μg-atoms/liter. In both species, yields of tops and roots were significantly less at 25.0 μg-atoms/liter than at lower selenium concentrations (p < 0.01). The results indicated that growth was adversely affected when the concentration of selenium in mature leaf tissue reached 0.2 to 0.8 μg-atom/g dry weight. |
