Plant growth promoting rhizobacteria for winter wheat

摘要: The association of winter wheat (Triticum aestivum L. cv. Norstar) with root-colonizing bacteria (rhizobacteria) was studied in potted soil experiments the growth chamber. Thirty-six known bacteria, some which have been reported to stimulate plant growth, and 75 isolates obtained from rhizosphere were tested for their effects on development two different soils. Two 12 stimulated wheat. Of these, most effective nine that significantly (P < 0.01) increased height, root shoot biomass, number tillers. promoting Three these strains tentatively classified as Pseudomonas aeruginosa, each cepacia, fluorescens, putida. Some induced significant increases seedling emergence rates (or) demonstrated antagonism vitro against Rhizoctonia solani Le...
