BR—blue (447 nm), red (638 and 665 nm), far-red (731 nm); BRG—BR with supplemental green (520 nm); BRY—BR with supplemental yellow (595 nm); BRO—BR with supplemental orange (622 nm). Total PPFD maintained at 300 µmol m^-2 s^-1, changing the input of red 665 nm. The data were processed using one-way analysis of variance (ANOVA), Duncan’s multiple range test at the confidence level p = 0.05. Presented values marked by similar letters do not differ significantly. Samples were taken from the central vessel part, and one vessel represented one replicate, three biological replicates were performed (n = 3). BR, blue-red; BRG, blue-red-green; BRY, blue-red yellow; and BRO, blue-red-orange.
