Growth, physiological characteristics, and fruit quality of Micro-Tom tomato affected by phosphor-doped light conversion plates.

In Micro-Tom tomato, phosphor-doped fluorescent light conversion plate T3 (SAO) increased fruit fresh weight by 22.76% and leaf photosynthesis Pn by 61.26% versus CK1.

• Why it matters: Artificial light supplementation is costly, so a passive spectral-regulation approach is needed to improve facility vegetable growth and fruit quality under modified light environments.
• What they did: Micro-Tom tomatoes were grown with no light conversion plate (CK), a blank PP plate without fluorescent powder (CK1), or four phosphor-doped light conversion plates (T1–T4), then growth, photosynthesis, and fruit quality were assessed.
• The result: T4 (Ca2MgWO6: Na+, Gd3+, Mn4+) promoted earlier tomato fruit coloring and improved fruit quality, supporting fluorescent powder plates as potentially low-energy spectral regulation strategies.
