Abstract
Under influence of the UV-B radiation (UV-BBE = 4 kJ·m-2·d-1, 15 days), plants of oat (Avena sativa L.) growing in controlled conditions of the temperature (17°C/15°C, day/night) and light (PPFD = 150 µmol·m-2·s-1) showed undesirable changes of the biometrical and physiological features. Considering the biometrical features, from among the examined three varieties (Akt, Bajka, Cacko), the most sensitive was the naked Cacko variety it had shortened and stenosed leaves, and diminished dry mass of plants. Plants of the traditional husked Bajka variety showed higher tolerance to the used UV-B dose, had less disturbed photosynthetic apparatus than the investigated naked varieties Akt and Cacko.
