Diploid (2n) and tetraploid (4n) seedlings were used in this study to access the optimal light quality for the growth of Anthurium andraeanum Pink Champion seedlings. Different LED light configurations with varying ratios of red light (R) and blue light (B) served as the light source, while fluorescent daylight lamps were used as the control (CK). Seven types of light qualities were set up: CK, R, B, R5∶B5, R6∶B4, R7∶B3, and R8∶B2. The study evaluated how different light qualities affected the growth of A. andraeanum seedlings, as well as the contents of soluble sugar (SS), soluble protein (SP), hydrogen peroxide (H2O2), and malondialdehyde (MDA) in the leaves. Additionally, the activity of superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) was measured. The results indicated that, compared with the control, red light (R) reduced leaf width, leaf area, and biomass of the two types of seedlings, and increased the POD activity in both seedlings, also the CAT activity and MDA content in the 2n seedlings. Blue light (B) significantly decreased the biomass, SS, and H2O2 content of the 4n seedlings, and increased the CAT and POD activity in both 2n and 4n seedlings, and the SOD activity in the leaves of the 2n seedlings. The combination of red and blue light qualities had the ability to mitigate the growth reduction or MDA increase caused by the individual light types. The combined red and blue light treatment increased the number of leaves, leaf area, leaf width, root length, biomass, SP content, and SOD and CAT activity in both types of seedlings. As the proportion of red light increased, biomass and protective enzyme activity initially rose and then declined, peaking under the R7∶B3 treatment. Conversely, H2O2 and MDA content exhibited an inverse trend. In conclusion, the appropriate ratio of combined red and blue light significantly promotes the morphogenesis and biomass accumulation of A. andraeanum seedlings, and enhances the antioxidant capacity. After a comprehensive evaluation using membership functions, R7∶B3 was determined to be the most effective among the seven light qualities, making it the optimal choice for the growth of A. andraeanum seedlings.
