Sole-source Lighting of Lettuce that Increased Yield Had No Negative Effect on Postharvest Longevity
HortScienceThe effects of sole-source lighting on the growth and yield of hydroponically grown lettuce have been extensively studied, but research of postharvest performance is limited.

Scientia Horticulturae, 2020 Abstract Manipulating the radiation spectrum of sole-source lighting (SSL) with light-emitting diodes (LEDs) enables the regulation of growth, development, and quality attributes of ornamental transplants. We quantified growth responses and subsequent flowering of annual bedding plant seedlings grown at 20 °C under eight SSL combinations of blue (B ...

Temporally increasing light intensity produces similar lettuce growth more efficiently than fixed high light [PDF]
Frontiers in Plant ScienceSole-source light-emitting diode (LED) lighting is essential in growth chambers, indoor farms, and spaceflight settings. Although lettuce (Lactuca sativa) is typically grown under fixed photosynthetic photon flux densities (PPFDs), dimmable LEDs enable ...

Growth and Physiological Responses of Lettuce Grown under Pre-Dawn or End-Of-Day Sole-Source Light-Quality Treatments [PDF]
Horticulturae, 2018 The objective of this study was to evaluate growth and physiological responses of ‘Cherokee’ and ‘Waldmann’s Green’ lettuce (Lactuca sativa) exposed to small changes in light quality and intensity within a 24-h period. Three

Growth and morphological responses of gerbera seedlings to narrow-band lights with different light spectral combinations as sole-source lighting in a controlled environment [PDF]
Canadian Journal of Plant Science, 2021 To optimize light-emitting diode (LED) spectral recipes for gerbera (Gerbera jamesonii) seedling propagation, seed germination and seedling morphology, biomass, flowering, and storage quality were observed in four cultivars, ‘Midi Dark Purple’, ‘Majorette Red Dark Eye’, ‘Maxi Pink’, and ‘Maxi White’, under six spectrum treatments: (1) FL, cool white ...

Light Intensity and Light Quality from Sole-source Light-emitting Diodes Impact Phytochemical Concentrations within Brassica Microgreens [PDF]
Journal of the American Society for Horticultural Science, 2017 Multilayer vertical production systems using sole-source (SS) light-emitting diodes (LEDs) can be an alternative to more traditional methods of microgreens production. One significant benefit of using LEDs is the ability to select light qualities that have beneficial impacts on plant morphology and the synthesis of health-promoting

Characterizing the Spatial Uniformity of Light Intensity and Spectrum for Indoor Crop Production
Horticulturae, 2022 Maintaining uniform photon irradiance distribution above the plant canopy is a fundamental goal in controlled environment agriculture (CEA). Spatial variation in photon irradiance below the light saturation point will drive differences in individual ...

Spectral effects of light-emitting diodes on plant growth, visual color quality, and photosynthetic photon efficacy: White versus blue plus red radiation. [PDF]
PLoS ONE, 2018 Arrays of blue (B, 400-500 nm) and red (R, 600-700 nm) light-emitting diodes (LEDs) used for plant growth applications make visual assessment of plants difficult compared to a broad (white, W) spectrum. Although W LEDs are sometimes used in horticultural

Effects of Daily Light Integral on Compact Tomato Plants Grown for Indoor Gardening
Agronomy, 2022 Our objective was to characterize the growth, physiological responses, fruit yield, and quality of tomato (Solanum lycopersicum L.) plants grown under different daily light integrals (DLIs) and photoperiods. In experiment I, nine compact tomato cultivars
