Abstract

Aim. The article dedicated to the investigation of the influence of the supplemental lightening by the solar-powered lamps on the growth, development and the grain productivity of the oat cultivar Nezlamny during the cultivating in glass greenhouse under the short growing day conditions. Methods. The solar-powered lamps Expert Light ELWf-SGL-S11107 5P were used for the constant supplemental lightening. The lamps were exposed to the completion of the oat development. After the grain ripening, 10 plants in each variant were selected evenly of the plot area for analysis of the growth characteristics and the grain productivity elements. The next parameters were analyzed: the stem length (Ls), the main panicle length (L), the grains number in the panicle, (G); the grains weight from the panicle, (W). The obtained data were analyzed statistically. Results. Besides of the plants architecture alteration, the decrease of the grain productivity was shown in the prevailing majority plants affected by the constant supplemental solar-powered lamps lightening. Conclusions. The constant supplemental lightening by the solar-powered lamps may be the stressor negatively influenced the morphogenesis and the grain productivity of the oat plants.

Keywords: supplemental lightening, solar-powered lamps, oat, changes of morphogenesis and productivity.
