- Intervention effect Combined nitrogen prevented root nodules in inoculated Lotus seedlings.
- Intervention effect Combined nitrogen prevented root flavolans in inoculated Lotus seedlings.
- Observation Nodulated seedlings in nitrogen-free solution had root flavolans.
- Association Flavolan synthesis coincided with nodule development.
- Intervention effect High single doses of NH4NO3 stimulated Lotus pedunculatus growth.
- Intervention effect High single doses of NH4NO3 suppressed nodulation.
- Intervention effect High single doses of NH4NO3 suppressed nitrogen fixation.
- Intervention effect Continued low-dose NH4NO3 increased nitrogen fixation by up to 500%.
- Association Higher fixation accompanied increased nodule fresh weight.
- Association Higher fixation accompanied lower root flavolan content.
- Intervention effect Nitrogen pretreatment could not change the ineffective NZP2213 nodule response.
