the effects of plant growth promoting rhizobacteria (pgpr) on growth and physiological characteristics of seedlings corylus avellana were determined in a forest nursery. for this purpose, in a completely randomized design (crd) and four replicates, three putative bacteria, including pseudomonas putida, bacillus subtilis and enterobacter cloacae, as alone and mixed, were examined. the greatest h...

The article discusses the ability of strains plant-stimulating rhizobacteria (plant-growth-promoting rhizobacteria, PGPR) Azospirillum baldaniorum Sp245, brasilense Sp7, SR80, SR88, Cd, Ochrobactrum cytisi IPA7.2 and Enterobacter ludwigii K7 to stimulate growth assimilation apparatus productivity winter soft wheat Novoershovskaya variety in conditions Left Bank Saratov region. bacteria stimulat...

Studies were done to evaluate specific strains of plant growth promoting rhizobacteria (PGPR) for induced resistance against cucumber mosaic cucumovirus (CMV) in tomato. In greenhouse experiments where plants were challenged by mechanical inoculation of CMV, the percentage of symptomatic plants in the most effective PGPR treatments ranged from 32 to 58%, compared with 88 to 98% in the nonbacter...

to date there is not progress commercially production and large scale application of pgpr in agriculture. one reason for limited commercial use of pgpr is variability, inconsistency and irreproduciblility of results between laboratory, greenhouse, and field trials. these problems with pgpr arises from variation in crops and cultivars, the physical, chemical and biological composition of  soils,...
