Abstract

 The influence of disturbance in water availability to electron flow in photosystem II was studied in five cultivars of sunflower. The results showed unaffected optimal quantum yield of photosystem II in the plants exposed to limited water supply, indicating the short-term tolerance of photosynthetic processes to acute water deficiency. Effective quantum yield of photosystem II was affected by interruption of water flow through the plants. Cultivar Labud exhibited the greatest sensitivity to water deficiency.
