摘要: In the absence of a combined N source in aqueous environment, N2 fixation by endophytic Anabaena can provide Azolla-Anabaena azollae symbioses with their total requirement. When sorces such as ammonium, nitrate or urea are present, these associations assimilate exogenous sources and fix atmospheric simultaneously.
