Abstract: | Summary Bacteria from the nodules ofLupinus angustifolius L.,L. digitatus Forsk., andL. luteus L. have been isolated, and the symbiotic relationships of nine of these strains and the three lupin species investigated in a glasshouse experiment. All symbioses were effective and no interaction or specificity was detected among the symbionts.Soil factors modified expression of the strains' symbiotic abilities in the field, but several strains have shown successful symbiosis with all three lupin species.One lupin species,L. digitatus, nodulates freely under natural conditions in Western Australia, whereasL. luteus andL. angustifolius do not. This lupin is more readily infected by native strains of rhizobia than the others. |
