effect of cadmium on the efficiency of development of legume-rhizobium symbiosis

Screening of nodule bacteria (rhizobia) forming symbiotic relationships with legumes has been performed in order to isolate strains resistant to cadmium ions in a wide range of concentrations (6–132 mg/kg). The effect of cadmium salts (6, 12, 24 mg/kg) on the legume-rhizobium symbiosis of the pea Pi...

Summary:Screening of nodule bacteria (rhizobia) forming symbiotic relationships with legumes has been performed in order to isolate strains resistant to cadmium ions in a wide range of concentrations (6–132 mg/kg). The effect of cadmium salts (6, 12, 24 mg/kg) on the legume-rhizobium symbiosis of the pea Pisum sativum L. with Rhizobium leguminosarum and of the fodder galega Galega orientalis Lam. with Rhizobium galegae has been studied under experimental laboratory conditions. No statistically significant differences have been revealed in the growth and biomass of plants with regard to the control in the range of concentrations given above. However, it was found that cadmium inhibited nodulation in P. sativum and stimulated it in G. orientalis.
