Total content of monosaccharides in leaves of cucumber transplants under high-
power solid-state lighting modules were less than under “SON-T Agro” lamps (Fig. 9).
But content of maltose was significantly higher in plants under modules with the main
set of LEDs and under module nm s with supplemental yellow 595 nm and orange
622 nm LEDs. Supplemental yellow light particularly stimulated synthesis of disaccha-
rides. Plants in this module accumulated three times more maltose than plants in control.
There was also detected some sucrose. Cucumber transplants in modules supplementary
illuminated by 380 nm and 595 nm LEDs accumulated the smallest content of
monosacharides (Fig. 9).
