Information About Author:

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
