title: Rhizobium leguminosarum inoculation decreases damage to faba bean (Vicia faba) caused by broad bean mottle bromovirus and bean yellow mosaic potyvirus.
abstract: Faba bean (Vicia faba) plants were inoculated with rhizobia and then their sap was infected with broad bean mottle bromovirus (BBMV) or bean yellow mosaic potyvirus (BYMV) in a field experiment. Both viral infections significantly decreased shoot and root dry weight, number of nodules, nodule dry weight, numbers of flowers and pods/plant, total plant N, grain yield and N2 fixation. However, inoculation withRhizobium leguminosarum significantly increased all these parameters, both in healthy and virus-infected plants. Although BYMV was more destructive than BBMV, inoculation with rhizobia could be used, with other control measures, to limit damage by both viruses.
