Response of Strawberry to the Substitution of Blue Light by Green Light in an Indoor Vertical Farming System

Indoor production systems with light emitting diode (LED) lamps are a feasible alternative for increasing strawberry productivity by reducing the incidence of pests and diseases damage caused extreme weather events. Blue (BL) red (RL) LED considered most important spectra photosynthesis crop yield; however, recent studies have demonstrated that beneficial effects green (GL) been underestimated. This information would be particular importance in controlled-environments/vertical farming as it may lower input costs enhance efficiency quality marketability. The present study aimed to define effect GL combination BL strawberry. A proportion 20% (20% + 60% RL) total photosynthetic photon flux density was plant growth productivity; 27% (12% 61% detrimental or comparable 6% (36% 58% RF). Total dry mass increased 51% when plants were illuminated compared those GL; impacted part root 155%. higher yield observed at 20%, but further resulted reduced yield. exhibited transpiration, stomatic conductance, internal CO2, which turn instantaneous intrinsic water-use efficiency. Plants highest GL) soluble solids fruits still values obtained acceptable (8.25 °Brix); these contained high sugars phenolics concentration antioxidant scavenging capacity. High proportions associated leaf fruit Ca P K, due allocation biomass roots. In conclusion, best parameters, enhanced net rate, attributes. this also other high-value horticultural crops suitable indoor vertical farming.
