Abstract

Changes in photosynthetic activity and agronomic parameters as the result of low water supplies and heat stress were examined in two winter wheat varieties. These extreme conditions had a substantial influence on physiological processes and could thus exert a negative effect on plant productivity. The plants responded to reduced water supplies by stomatal closure, resulting in a considerable decline in transpiration and photosynthetic activity. By contrast, heat stress stimulated transpiration, as the stomata were more widely open than in the control plants on the second day of treatment. By the 8 th day, however, these processes again exhibited a decrease. In addition, thanks to the reduced grain filling and unfavourable changes in the carbohydrate metabolism during ripening, the stress factors led to a drastic reduction in yield parameters.
