SYNTHESIS OF ASCORBIC ACID AND MORPHOGENESIS OF ARABIDOPSIS THALIANA BY ADAPTATION TO UV RADIATION // Tomsk State Pedagogical University Bulletin. 2009. Issue 6 (84). P. 126-131

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.

VITAL ACTIVITY OF LACTUCA SATIVA AND SOIL MICROORGANISMS UNDER FLUORESCENT FILMS // Tomsk State Pedagogical University Bulletin. 2011. Issue 8 (110). P. 78-84

Productivity of Lactuca sativa, variety Moskovsky parnikovy growing in protected cultivation under fluorescent film luminescent with maximum of 615 nanometers is studied in dynamics. Change of conditions of plant cultivation by fluorescent film promotes accelerated growth, development and productivity improvement of Lactuca sativa relative to plants growing under unmodified film. Increase in productivity of Lactuca sativa in 1.5 times under fluorescent films is determined by increase in ratio IAA/ABA and decrease in content of АA in plants, and also conjugated with change of enzymatic activity of aboriginal soil microflora.

MORPHOGENESIS AND HORMONAL BALANCE ARABIDOPSIS THALIANA BY EXPOSURE TO UV-A LIGHT LOW INTENSITY // Tomsk State Pedagogical University Bulletin. 2013. Issue 8 (136). P. 9-17

The article deals with the effect of long-wave ultraviolet (UVA) radiation in the low-intensity white light (BS) on morphogenesis, hormonal balance, the content of photosynthetic pigments (SAF) and ascorbic acid (AA) Arabidopsis thaliana (L.) Heynh. wild-type and mutant Ler hy4, having irregularities in the synthesis of cryptochrome 1 (CRY1). The plants of both lines inhibition of growth processes and reducing the real seed production in response to the additional exposure to UV-A light was associated with a change in the balance of endogenous hormones - decrease in the amount of indole acid (IAA), and increased levels of abscisic acid (ABA), change the content of FAK and AK. On the basis of differences in the dynamics of seed production plants has been suggested the possible involvement of the photoreceptor CRY1 in regulating morphogenesis of plants to UV-A light of low intensity.
