“…Specifically, seedlings precultivated under NS1 formed the longest roots, but the greatest root biomass was achieved under NS1 and AP67 (the highest B portion among the LEDs). This is in contrast with a previous study with Red Rubin hybrid basil, which had the shortest roots under the NS1 light regime, while new root biomass generally followed the same pattern (Bantis et al, 2016). New root biomass production mainly determines RGC, since it refers to the mass of both primary and secondary roots.…”

“…The effect of LEDs on a great deal of horticultural [lettuce (Shen et al, 2014), cucumber (Hernández and Kubota, 2016), basil (Bantis et al, 2016)] and ornamental [Phalaenopsis (Ouzounis et al, 2014)] plants has already been studied. However, only a few studies have been conducted using forest tree species as test material (Astolfi et al, 2012;Riikonen, 2016;Smirnakou et al, 2016).…”

high-pressure sodium, incandescent, and metal halide. Light-emitting diode (LED) technology is constantly growing and employed in greenhouses, nurseries, and growth chambers. Compared to the rest of the lamp types, LEDs have longer lives, minimal heat emission (allowing the plants to be placed close to the lamp fixtures), and the option of spectral setting. In addition, their high energy conversion efficiency leads to lower utilization cost

“…Indeed, the phyllosphere microbiota uses leaf surface resources, such as amino acids, carbohydrates, and organic acids, passively leaked by plants [114]. A combination of red, blue, and white light enhances soluble sugar and nitrate concentrations in basil plants [115]. However, a low R:FR ratio downregulates the activity of the key enzymes involved in nitrogen assimilation (nitrate reductase, nitrite reductase, and glutamine synthase), which may impact cell metabolism [58].…”

Light and Microbial Lifestyle: The Impact of Light Quality on Plant–Microbe Interactions in Horticultural Production Systems—A Review

Horticultural greenhouse production in circumpolar regions (>60 • N latitude), but also at lower latitudes, is dependent on artificial assimilation lighting to improve plant performance and the profitability of ornamental crops, and to secure production of greenhouse vegetables and berries all year round. In order to reduce energy consumption and energy costs, alternative technologies for lighting have been introduced, including light-emitting diodes (LED). This technology is also well-established within urban farming, especially plant factories. Different light technologies influence biotic and abiotic conditions in the plant environment. This review focuses on the impact of light quality on plant-microbe interactions, especially non-phototrophic organisms. Bacterial and fungal pathogens, biocontrol agents, and the phyllobiome are considered. Relevant molecular mechanisms regulating light-quality-related processes in bacteria are described and knowledge gaps are discussed with reference to ecological theories.

Based on available literature, ecology and economy of light emitting diode (LED) lights in plant foods production were assessed and compared to high pressure sodium (HPS) and compact fluorescent light (CFL) lamps. The assessment summarises that LEDs are superior compared to other lamp types. LEDs are ideal in luminous efficiency, life span and electricity usage. Mercury, carbon dioxide and heat emissions are also lowest in comparison to HPS and CFL lamps. This indicates that LEDs are indeed economic and eco-friendly lighting devices. The present review indicates also that LEDs have many practical benefits compared to other lamp types. In addition, they are applicable in many purposes in plant foods production. The main focus of the review is the targeted use of LEDs in order to enrich phytochemicals in plants. This is an expedient to massive improvement in production efficiency, since it diminishes the number of plants per phytochemical unit. Consequently, any other production costs (e.g. growing space, water, nutrient and transport) may be reduced markedly. Finally, 24 research articles published between 2013 and 2017 were reviewed for targeted use of LEDs in the specific, i.e. blue range (400-500 nm) of spectrum. The articles indicate that blue light is efficient in enhancing the accumulation of health beneficial phytochemicals in various species. The finding is important for global food production. © 2017 Society of Chemical Industry.
