Effects of high light (2000 mmole quanta m^-2s^-1) intensity at low (4°C), room (25°C) and high (40°C) temperature on fast fluorescence kinetics of faba bean (Vicia faba L.) and spinach (Spinacia oleracia L.) leaves were studied. Recovery of fluorescence parameters from high light stress at low light intensity (125 mmole quanta m^-2s^-1) or under continuous darkness was studied. Heat treatment at 40°C enhanced F₀ emission. However, high irradiance quenched heat induced increase in F₀. The F₀ values of Vicia faba did not change at low and room temperature. However, that for spinach gradually decreased at room temperature but remained same at low temperature. FM values of both spinach and faba bean decreased significantly with higher temperature and high light treatments. However, quantum efficiency, relative performance index and driving forces for energy fluxes for electron transfer decreased, but that for dissipation increased with higher temperature and high light treatments. There was a recovery from the high light and high temperature stress phenomena under low light at room temperature. Low light treatment was more effective in the recovery process than the dark treatments. A sliding model for plastic and elastic stress responses is proposed for assessment of stress recovery phenomena, which can be applied to combined stress responses.
