Tolerance to acidity (pH 4.2 to 4.6), low P (1 to 6 ..mu..M) and high Al (15 to 40..mu..M) for 100 strains of Rhizobium trifolii was assessed in liquid culture media in the laboratory. Response to acidity and Al varied among strains as evidenced by lower maximum cell densities and reduced growth rates, most preceded by a lag phase. Tolerance to acidity did not imply tolerance to Al in all cases. Strains were capable of tolerating higher levels of Al if acidity was reduced. Limitations in rhizobial growth due to low P concentrations were not as severe a stress as high acidity or high Al concentration.
