【 摘 要 】

The research presents the results of experimental findings of cucumber growth Partner F1 that doesn't exceed a cubic metre of quantity at artificial agroecosystems: soil was used as a substratum, there was no natural source of light, watering was provided according to plant needs. Four LED light sources with different spectra were used as luminous elements: -two sources on the basis of white light-emitting diodes with a correlated color temperature (CCT) of 4000 K and a color rendering index Ra-80 with LEDs emitting maximum optical spectrum of 625 and 630 nm in the quantitative ratio of 9:2 and 1:1; -two ones were designed using white light-emitting diodes distinguished by a measure of a CCT (3000 K and 4000 K). It was shown the possibility of cucumber development under all explored luminous spectra on the basis of morphometric measures and analysis of productivity of four plant hybrid groups that went through the whole reproduction cycle from the seed development to fruit-bearing plants. More intensive development of the vegetative parts and the early beginning of the reproductive plant stage under spectra with an extra red-blue component were identified. Plants grown under white LEDs had better state of vegetative parts on the reproductive stage.
