摘要：

The quantum yield of PSII photoinactivation in pea leaves at low photon exposure was 3 x 10(-7) mol PSII per mol photons absorbed by PSII and 2.5 x 10(-8) at high photon exposures (mel photons m(-2)), regardless of photomodulation of chloroplasts. We postulate that the dose-response behaviour of PSII photoinactivation, which depends on the number of photons absorbed, results from the balance of light consumption with supply.
