Effects of chilling and water stress on photosynthesis of cucumber and pea leaf discs and its relation to light

Effects of chilling and water stress on photosynthesis of cucumber and pea leaf discs and its relation to light

Acta Phytophysiologica Sinica 13(4): 386-394

In leaf discs of chilling resistant peas, photosynthetic quantum yield and chlorophyll fluorescence were not affected by exposure to 5 degrees C but in chilling sensitive cucumber both were decreased in the light but not in darkness. In cucumber under mild chronic water stress, the max. photosynthetic rate was most sensitive to stress with light and CO2 saturation. Quantum yield was reduced by mild water stress in full sunlight.
