Introduction LED lights have a lower environmental impact than traditional lights due to a series of factors such as their wavelength specificity and narrow bandwidth, high energy-conversion efficiency, small volume, longer life, low thermal energy output. Concerning plant growth, the uses of LED lights provide specific wavelength as well as the possibility to adjust light intensity/quality. The increasingly need to reduce energy consumption worldwide, raised the necessity to improve LED lights… Expand

Preliminary Investigation of LED Lighting as Growth Light for Seedlings from Different Tree Species in Growth Chambers
TLDR
It is found that LED-induced reduction of chlorophyll contents in beech and holm oak leaves resulted in an increase of the carboxylase capacity of Rubisco in the same plant species suggesting an improvement of light-use-efficiency in these plants. Expand
LEDs for Energy Efficient Greenhouse Lighting
TLDR
In a comparative economic analysis of traditional vs. LED lighting, it is shown that the introduction of LEDs allows reduction of the production cost of vegetables in the long-run of several years, due to the high energy efficiency, low maintenance cost and longevity of LEDs. Expand
The application of LEDs as assimilation light source in greenhouse horticulture: a simulation study
The application of light-emitting diodes (LED’s) as potential source for assimilation lighting in greenhouse production systems opens up a range of new possibilities. LED’s produce light in a veryExpand
LED Lighting in Horticulture
TLDR
Solid-state lighting based on the use of light-emitting diodes (LEDs) is potentially one of the biggest advancements in horticultural lighting in decades, and LEDs are the first light source to have the capability of true spectral composition control. Expand
A novel approach of LED light radiation improves the antioxidant activity of pea seedlings
TLDR
The contribution of red light to significant β-carotene expression and antioxidant activity for nutrition and health benefits and blue light to seedling weight and chlorophyll induction of radiated pea seedlings are emphasized. Expand
Light-emitting diodes as a light source for photosynthesis research
TLDR
Photosynthesis research including electron transport, carbon metabolism and trace gas emission studies should benefit greatly from the increased reliability, repeatability and portability of a photosynthesis lamp based on light-emitting diodes. Expand
Growth and ecophysiology of succulent seedlings under the protection of nurse plants in the Southern Chihuahuan Desert
TLDR
This study measured the variables related to chlorophyll fluorescence: Quantum yield of photosystem II photochemistry (ΦPSII) and electron transport rate (ETR), as well as relative growth rate (RGR) and its components (net assimilation rate, NAR, and leaf area rate, LAR), root to shoot (R/S) ratio, and relative water content (RWC) for seedlings transplanted under nurse plants and seedlings transplantanted under direct sunlight.

Spectral effects of LEDs on chlorophyll fluorescence and pigmentation in Phalaenopsis 'Vivien' and 'Purple Star'.
TLDR
The permanent downregulation of PSII moved a substantial part of the thermal dissipation from the light regulated NPQ to non-regulated energy losses estimated by ΦNPQ and ΦNO and the difference found in the balance between ΦPSII and λNPQ in 'Vivien' disappeared when Φ NO was included in the thermal Dissipation.

Horticultural Lighting in the Netherlands: New Developments
In the Netherlands about 2000 ha of glasshouses is equipped with supplementary assimilation light (SL), which is about 19% of the total glasshouse area. Besides increased production, SL results inExpand
Influence of soil temperature and water content on fine-root seasonal growth of European beech natural forest in Southern Alps, Italy
In tree species, fine-root growth is influenced by the interaction between environmental factors such as soil temperature (ST) and soil moisture. Evidences suggest that if soil moisture and nutrientExpand
