Bradyrhizoblum - mungbean (Vigna radiata) symbiosis was influenced by the application of nitrate in combination with.yrlngaldehyde. Application of nitrate alone at lower concentrations (2, 5 mM) caused a reduction at initial stage (10 DAS) while at later stage (35 DAS-45 DAS) enhanced the nodulation status (nodule number, nodule weight) and nodule efficiency (acetylene reduction activity). Higher concentration of nitrate (10 mM) caused a reduction in nodule number, nodule weight and acetylene reduction activity. Syringaldehyde alone improved the nodulation status and nodule efficiency while it acted synergistically when applied in combination with nitrate. These effects were also reflected in the biomass of plants.
