| Abstract: | Influence of ascending nitrogen supply on the development of Rhizobium symbiotic bacteria on peas ( Pisum sativum L. ssp. sativum ) in nutritive culture solution
The effect of ascending N-supply with 4 different levels from 0.1 to 1.56 mg atom/L culture solution on juncture, quantity and development of Rhizobium bacteria on peas variety Stehgolt was thoroughly investigated. Contemporaneously, all the inoculated plants set on several noduls. The number of nodules formed per plant was negatively and hasty influenced by the ascending N-supply. Higher N-provision lessen the number of Rhizobium nodules per plant, however, these few achieved their active N2-Fixation phase (Leghämoglobin formation stage) earlier than those formed under insufficient N-supply. |
