1 | On the example of cultivation of sprout cabbage of a kind «Nadezhda» in the summer period influencing of meteorological conditions 1999-2003 years to productivity of correction light films for protection closed soil is investigated. With usage of techniques of biological testing of films is rotined, that challenging influencing to growth and development of plants («polysvetany» effect) correction light films render only at enough favorable temperature and light meteorological conditions, giving considerable effects of increase of biomass of spout and economic productivity of horse radish. At a decrease of mean temperatures on 5-7 °C or increase of temperatures on 8-10 °C from optimum for cultivation of plants and long-term period of dense cloud cover during realization of experiment in conditions of closed soil without an auxiliary illumination and heating «polysvetany» effect is not watched. Reproduction of effect in region of risky agriculture (Tomsk) in the indicated term is reached 40% in most unfavorable for an agriculture spring period and 75 % in the summer period | 1267 | ||||
2 | The technique of definition of influencing of features of photophysical characteristics of correction light films on growth and development in conditions of closed soil of a summer horse radish of a kind “Ladushka” – biological testing of correction light films is designed. The technique is encompass bayed definition of a number of a number morphometry, biochemical parameters, economic productivity of plants at their cultivation in the summer period in conditions of a closed soil under correction light films. Considerable, up to double and more, the changes of economic productivity of culture under correction light films as contrasted to not by modified polyethylene films of the same technological parameters, indicate high response of plants to changes of a spectral components of electromagnetic radiation created by correction light films. The technique allows getting the information about features of influencing of different photophysical characteristics of correction light films on growth and development of plants in the summer period and it is addition to design earlier to technique of biological testing of correction light films in the spring period at cultivation of sprout of a cabbage | 1223 | ||||
3 | The incorporative effects of luminescent red radiation of low intensity, generated by correcting light polyethylene films and redundant ultraviolet-A radiation on morphogenesis of Arabidopsis thaliana (L.) Henh. of wild-type Ler and two light mutants hy3 and hy4 deficient in synthesis phytochrome B and cryptochrome 1 accordingly were investigated. Wild-type plants, cultivated under these correcting light films have no any changes in its development, while hy4 mutant exhibits increased development process and growth. Lethal effect of UV-A radiation was noted in the process of growing hy3 mutant, especially in the initial stage of true leaves development. Results from studies indicate regulatory interaction of low intensity red luminescent radiation and redundant ultraviolet-A radiation on stimulation and inhibition of plants growth and productivity | 1129 | ||||
4 | The article studied the influence of luminiscent radiation of photoluminescent films on augmentation of productivity of plants in a greenhouses, and also the reflected, absorbed and dissipated solar light photoluminophore particles in films. It is experimentally erected, that the basic contribution to augmentation of productivity of plants to a greenhouses under photoluminescent films imports the luminescent radiance generated by films. Productivity also is spotted by a relation getting on a plant direct and a diffused light. Keywords: a greenhouse, a solar light, a photoluminescent film, luminescent radiation, productivity | 1309 | ||||
5 | 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. Keywords: Lactuca sativa, protected cultivation, fluorescent films, productivity, hormones, ascorbic acid, soil microflora | 1301 | ||||
6 | Productivity of Lactuca sativa L. Lolla Rossa in the conditions of protected cultivation under fluorescent polyethylene film and polyethylene terephthalate films (lavsan) was studied in the article. The change in the conditions of plants, growing with the use of modified polymer films, contributes to accelerated growth, development and productivity of L. sativa in relation to plants grown under unmodified polyethylene film. Increase of L. sativa productivity was attended with growth of ascorbic acid (AA) level and change in catalase activity in plant leaves. Keywords: unmodified polyethylene film, fluorescent film, lavsan, Lactuca sativa L., productivity, ascorbic acid, catalase | 1158 | ||||
7 | The use of photoselective polyethylene films with thermic properties used as greenhouse cover materials at cultivation of Eruca sativa Mill., Korsika resulted in change of vegetative growth and plants development. The thermic films have IR-reflecting properties (700–1400 nm) due to low-emission coatings with copper compounds (film TF1) and compounds of silver and copper (film TF2) on the surface of polyethylene films. The use of thermic films was conducive to decrease in wide fluctuations in day and night temperatures in greenhouses, because of increase in night temperatures up to 2 °C compared to unmodified polyethylene film. The change of light and temperature growth conditions of E. sativa by thermic film (TF-2) resulted in increase the yield (leaf number, fresh weight, and dry weight). Increase in productivity up to 60 % was followed by the rise in ascorbic acid level in plant leaves. Thermic film TF-1 did not contribute to change of plant growth, development and productivity of Eruca sativa compared to unmodified polyethylene film.
