Mechanism of photoinactivation in photosynthetic systems I. The dark reaction in photoinactivation1

摘要

1)General features of photoinactivation of chloroplast reactions under moderate light intensity were investigated.2)The effects of temperature and of intermittent illumination upon photoinactivation indicated that the process is not a simple photochemical reaction but includes some dark reactions.3)The action spectrum of the photoinactivation indicated that the energy absorbed by photosynthetic pigments is used for the process.4)The relative sensitivity and different time courses seen in the inactivation of various photochemical activities suggested the presence of different kinds of photoinactivation.
