Conteúdo: |
The nodules which developed on the roots of Pisum sativum after inoculation with Rhizobium leguminosarum bv. biciae strains showing a Hup + symbiotic phenotype and/or a high relative efficiency of electron transfer to dinitrogen (RE) had a high nitrogen content of their tissue. In comparision with the nodules initiated by a strain possessing the Hup - symbiotic phenotype or by a indigenous soil Rhizobium population, the nitrogen-rich root nodules contained up to four times more nitrogen (9.2% of dry mass). In the nitrogen-rich nodules, total amino acid, and especially Ala, Lys and Phe contents were significantly increased. The nitrogen-rich nodule symbiotic phenotype (Nrn) was well expressed, irrespective of pea cultivars and host plant age. If a strain showing the Nrn phenotype was applied in double-strain inocula, a significant correlation was found between increasing rates of the strain and increasing percentage nitrogen content of nodule tissue in the nodulated plants. |
