The role of root-associatedKlebsiella pneumoniae in the nitrogen nutrition ofPoa pratensis andTriticum aestivum as estimated by the method of15N isotope dilution


The technique of15N isotope dilution was used to verify that nitrogen was fixed and transferred to the plant byKlebsiella pneumoniae strain Pp in association withPoa pratensis orTriticum aestivum. Surface sterilized, sprouting seeds were inoculated withK. pneumoniae and grown in sand in modified Leonard jars. Potassium nitrate enriched with15N was used to… (More)
