SYNTHESIS OF ASCORBIC ACID AND MORPHOGENESIS OF ARABIDOPSIS THALIANA BY ADAPTATION TO UV RADIATION
We studied the influence of UV radiations of low intensity on the morphogenesis, accumulation of photosynthetic pigments and synthesis of ascorbic acid Arabidopsis thaliana (L.) Heynh. Wild type Ler and a mutant hy4, having infringement in synthesis cry1. Light adaptation of plants to their irradiation UV light is shown at the initial stage of the ontogenesis through synthesis and accumulation of ascorbic acid, change of dynamics of level of photosynthetic pigments. It is reflected in inhibition reactions of grows, in the slowed down development of reproductive bodies of plants and in lengthening of terms of vegetation. Among plants Ler these processes lead to decrease in real seed efficiency, among plants hy4, having infringements in synthesis cry1, changes is not revealed. The assumption is made, that the basic role in the course of adaptation to action of UV radiation of low intensity carry out not only photosynthetic pigments, but photoregulation pigments.
Keywords: arabidopsis thaliana, wild type Ler, a mutant hy4, UV radiation of low intensity, morphogenesis, efficiency, photosynthetic pigments, ascorbic acid
