Abstract
Arbuscular mycorrhizal fungi (AMF) is known to enhance the rate of photosynthesis in plants, but there is little information on whether this effect is maintained at low temperature when the development of AM fungi is restrained.
After 40 days of cultivations, we therefore investigated the influence of AM on gas exchange, photosystem II fluorescence and some photosynthesis-related biochemical parameters in cucumber seedlings under cold stress for 14 days in growth champers.
AMF (Rhizophagus irregularis), in contrast, had opposite effects on most of the determined parameters, and improved therefore the efficiency of photosynthesis of the cucumber seedlings both at cold stress and at control ambient temperature.
