| Abstract: | The short high temperature-induced inhibition of nitrogenase activity of Anabaena was re-moved to a certain degrce by the introduction of exogenous proline into the test system.Under weak lightcondition or in presence of photosynthetic inhibitors such as DNP or CCCP,the benefical effect of prolineon the nitrogenase activity of Anabaena driven by stress of high temperature was weakened.Theproline-supported nitrogenase activity of Anabaena under stress of high temperature was less evident whenexogenouse sucrose was present.When algal cells injured by high temperature were incubated in the aerobiccondition(in air)the benefical action of proline was higher than that in anaerobic condition(in Ar).The ad-dition of O_2,CO_2,N_2 or CO_2+N_2 to test systems respectively showed no enhancing effect of proline on thenitrogenase activity of Anabaena under stress of high temperature The higher benefical effect of proline onnitrogenase activity was observed when O_2 is added together with H_2. |
