The study found that when tomatoes were treated with partial far red light instead of red/blue LED lamps, the yield of tomatoes did not change, but due to the higher refractive index and increased degree of bite (increased "bite"), the overall taste increased.
These preliminary results were obtained from the lighting test at the Vereijken nursery in Beek en Donk, The Netherlands. The trial was conducted under the framework of the Guidance and mo nitoring of energy innovations in practice in the KAS ALS Energiebron program. Typically, the tomato variety Campari accepts 180 μmol/ m2 / s SON-T and 60 μmol/m2/s red/blue LED illumination. In this comparative test, the 60 μmol/m 2 /s red/blue LED was changed to 40 μmol/ m 2 / s red/blue and 20 μmol/ m 2 / s far red LED light treatment.
KAS ALS Energiebron Project: The Netherlands proposed the plan in 2011. It plans to reduce carbon dioxide emissions by 3.3MT by 2020, which is 48% lower than in 1990, and the greenhouse industry uses 20% of renewable energy.
Previous experiments at Wageningen University have shown that adding far-red light to LED or SON-T lighting can increase tomato yield and quality. Far-red light is not in the range of photosynthetically active radiation (PAR), but it can have a positive effect on photosynthesis, and it will affect the distribution of assimilation products, and more assimilation products will turn to the fruit part.
