Abstract
Plants of the red - leaved form of Karmezi lettuce varietie was grown at three irradiation levels of 80.60 and 25 mmol m-2 • s-1 with subsequent transfer of part of the plants To a high level of illumination with additional ultraviolet light. The production process, gas exchange and accumulation of anthocyanins were studied. It was shown that ultraviolet and high irradiation (80 mmol m-2 • s-1 ) stimulate the formation of anthocyanins in the lettuce plants.
