Victory onion (Allium victorialis) is an edible vegetation that has significant value as a non-structural carbohydrate and secondary metabolite supplier. Easily measured leaf variables will be useful to predict for the flexible adjustment of physiochemical parameters in a cultural regime in plant factory conditions. Red, green, and blue light-emitting diode (LED) spectra were used to culture victory onion sprouts. Compared to the green-light spectrum, the red-light spectrum promoted leaf width and area, specific leaf area, and dry mass, water content, fine root growth, and starch accumulation in shoots, but lowered concentrations of total flavonoids and saponins. Sprouts had their shoots cut, but there were limited interactive effects with light spectra on most variables. In general, shoot-cutting depressed growth of leaf morphology, shoot weight, water content, and soluble sugar content, but enhanced accumulation of secondary metabolites. We did not find any relationship between leaf variables and secondary metabolites. Instead, wider leaves with a larger area generally had greater dry mass, water content, and soluble sugar accumulation. Leaves with deeper green colours generally had the opposite effects.
