Green Light Improves Photosystem Stoichiometry in Cucumber Seedlings (Cucumis sativus) Compared to Monochromatic Red Light

Plants, 2021
It has been shown that monochromatic red and blue light influence photosynthesis and morphology in cucumber. It is less clear how green light impacts photosynthetic performance or morphology, either alone or in concert with other wavelengths.

Supplemental Blue Light Frequencies Improve Ripening and Nutritional Qualities of Tomato Fruits

Frontiers in Plant Science, 2022
Tomatoes (Solanum lycopersicum L. Micro-Tom) were grown in a plastic greenhouse. When plants anthesis, the 100 μmol m–2 s–1 blue light-emitting diode (LED) light (430 ± 10 nm) was supplemented from 6:00 to 18:00.
