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.

RESEARCH OF PROPERTIES OF PHOTOLUMINESCENT FILMS AT EXCITATION BY A SOLAR RADIATION // Tomsk State Pedagogical University Bulletin. 2011. Issue 8 (110). P. 119-123

The fluorescen properties of polyethylene photoluminescent films connected with injecting to their composition of photoluminophor on the basis of linkings of europium in excitation of UV by radiation of the sun are investigated. For the first time experimental measurement of rates of fluorescent radiation of a photoluminescent film at its exploitation in natural conditions are carried out. The maximum values of fluorescence intensity of films in investigated conditions make near to 8 mW/m2, average day from 0.5 to 2 mW/m2. For the first time the received results have allowed to make a quantitative estimation of fluorescent radiation intensity of photoluminescent films at effective cultivation under them plants in natural conditions. Reproducing of such indices can allow transferring effect studying to controllable laboratory conditions.
