| Abstract: | Striga spp. are obligate parasitic weeds of tropical cereals and generally have the same host range as rhizospheric bacteria of the genus Azospirillum. Four strains of Azospirillum brasilense, isolated from soil where sorghum is grown, have been tested for their effect on germination of Striga hermonthica seeds and on cereal (Sorghum vulgare) growth. Two out of four strains assayed significantly inhibited germination of the parasite. Moreover, one of the two strains showed a plant growth promoting (PGPR) effect. |
