Abstract
Aim. The effect of ultraviolet C (UV-C) radiation and cytokinin benzylaminopurine (BAP) on the growth and content of photosynthetic pigments in leaves of pea plants (Pisum sativum L.) was studied. Methods. Pea plants cultivar Aronis were irradiated by UV-C at a dose of 15 kJ/m2 with a power of 7 W/m2. Part of the non-irradiated plants was treated with BAP, part of the plants was treated with BAP one day before irradiation and part of plants were treated with BAP in one day after UV-C irradiation. Length and mass of plant shoots and roots were measured during the experiment. Content of photosynthetic pigments in leaves were determined during all time the experiment. Results. It was shown that pea plants growth delayed content of carotenoids in leaves reduced after the UV-C radiation of pea plants. Treatment of plants with BAP after the end of the UV-C radiation accelerated the restoration of photosynthetic pigments content. Conclusions. It was shown that UV-C radiation of pea plants by dose of 15 kJ/m2 caused inhibition of growth, decreasing photosynthetic pigments content in leaves. The BAP treatment after radiation stimulated the restoration of photosynthetic pigments content in the leaves.
