抄録

A respiration burst of rice leaf tissue slices infected by compatible blast fungus race with or without the application of probenazole or incompatible blast fungus race, or stimulated by one of the hyphal components was quantitatively analysed. A time at maximum rate of the augmentation phase and a half life time of the auto-inactivation phase were respectively determined. A time-sequential orderliness along either line of the time of maximum rate or the half life time was observed. A high correlation coefficient between the values of time of maximum rate and half life time was also observed. By the application of probenazole, both the time of maximum rate and half life time of respiration burst were shifted as in an incompatible combination even in a compatible infection. Superoxide anion and hydrogen peroxide generation were also observed when glucose was used as a respiratory substrate. The major oxidative product of glucose seemed to be gluconate.
