Abstract

Long term light emission was compared from leaves of paraquat-resistant and -susceptible tobacco plants. In the minutes time scale, delayed light emission of the two biotypes was similar both in kinetics and in intensity. However, after several hours in the dark, ultraweak light emission from leaves of resistant plants was about one third of the light emitted by susceptible samples. We suggest, that this difference is due to the higher activity of superoxide dismutase in resistant biotypes, earlier reported by Tanaka et al. (1988) (Plant Cell Physiol. 29, 743-746), and propose a model for the mechanism of ultraweak light emission from these samples.
