The relative size of the pool of electrons accumulated in stroma reductants during actinic irradiation, which can be donated to P700+via the intersystem chain, was estimated after short-term exposure of intact Zea mays leaves to elevated temperatures. When the temperature increased from 25 to 50 °C by 5 °C steps, the relative size of the stroma electron pool went through a maximum at around 30 °C, and decreased gradually thereafter.

Additional key words: heat stress; stroma reductants; Zea mays
