The bacteria were Bacillus subtilis, Bacillus megaterium, Aerococcus viridans, Bacillus cereus, Pseudomonas fluorescens, Pseudomonas putida, Agrobacterium radiobacter, Flavobacterium ferrugineum, Flavobacterium lutescens, Serratia marcescens, Micrococcus varians, Citrobacter freundii, Pediococcus pentosaceus and Staphylococcus saprophyticus. The predominant bacteria in the rhizosphere soil were Pseudomonas fluorescens, Bacillus subtilis and Bacillus megaterium. The predominant bacterias in the rhizoplane were Flavobacterium, ferrugineum, Flavobacterium lutescens and Bacillus subtilis. The predominant bacterias in the non-rhizosphere soil were Staphylococcus saprophyticus and Bacillus subtilis. The experimental soil was sandy loam in texture. There was a progressive increase in the rhizosphere effect with increase in plant age until the tenth week after seed sowing and subsequently there was a decline until the fourteenth week.]]>Abdel-Hafez, S.I.I.,1982Triticum vulgare cultivated in Saudi Arabia.]]>787986Abdel-Rahim, A.M., A.M.
