Title: Possibility of Controlling Bean Yellow Mosaic Virus on Faba Bean ( Vicia faba L.) by Rhizobium Inocnlation
Author: Osman, Awad G.; Elsheikh, Elsiddig A.E.
Abstract: Bean Yellow Mosaic Virus (BYMV) inoculum was applied after two, three and half or five weeks from sowing to faba bean cv. Agabat which was either uninoculated or inoculated with Rhizobium leguminosarum biovar. viceae strain TALI397 in a pot experiment. Inoculation with the virus after two and three and half weeks significantly decreased shoot and root dry weight, nodule number, nodule dry weight, number of flowers and pods per plant, total plant nitrogen and nitrogen fixation, whereas inoculation with Rhizobium has significantly increased these parameters. The reduction in plant dry weight and nodule number due to the viral treatments were correlated with the time of virus inoculation in a statistical model. The results indicate that faba bean plants suffer greatly from the virus infection when virus inocula are added early in the season. The results also indicate that Rhizobium strain TAL 13 97 is effective in fixing nitrogen in normal and in virus infected faba bean plants.
