Abstract
When bush bean plants (Phaseolus vulgaris L. cv. Improved Tendergreen) were grown in nutrient solution, yields were depressed by levels of NaCl up to 100 me/1. When trace metals Li, Sr and Co were applied, only the treatment with 100 me/1 NaClhad decreased yields for the trace metals but not significantly higher than control. The NaCl increased shoot concentrations of Zn, Cu and Si and Si in roots. When Sr, Li and Co were applied, NaCl tended to decrease their concentrations in shoots and also in roots except for Li.
