Abstract: The work was carried out in New Zealand from 1989-1991.The results showedthat exogenous H2 increased nitrogen fixing activity of Gunnera/Nostoc symbiont by nearly 100%, but decreased respiratory rate by nearly 50% simultaneously.Exogenous carbohydrateglucose) increased nitrogen fixing activity by nearly 100%, and increased respiratory rate bynearly 160% simultaneously. It also showed that carbohydrate glucose) was much betterthan H2 in maintaining and restoring nitrogen fixing activity ofGunnera/Nostoc symbiont.

Key words: Biological nitrogen fixation, Gunnera/Nostoc symbiont, Nitrogen fixing activity, Carbohydrate, Hydrogen
