Leaf soluble carbohydrate content of chrysanthemum cuttings exposed for 30 days to different light quality regimes (red (R), red and blue (R:B), red, blue and far-red (R:B:FR), white (W) and blue (B); see the spectrum in Figure 9). During the experiment, the photosynthetic photon flux density was set to 150 ± 5 µmol m⁻² s⁻¹. Six replicates per treatment were assessed. Columns with the same letters are not significantly different at p ≤ 0.05, according to Duncan’s multiple range tests. Bars represent SEM.
