Growth and Physiological Responses of Lettuce Grown under Pre-Dawn or End-Of-Day Sole-Source Light-Quality Treatments

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

The Expression of ELF4-Like Genes Is Influenced by Light Quality in Petunia

Agronomy, 2020
The signals from photoreceptors modify plant morphogenesis and regulate the timing of flowering. In the long-day plant petunia, flowering is accelerated under blue (B) and white (W) light compared to red (R) light.

Effect of Long-Term of He-Ne Laser Light Irradiation on Selected Physiological Processes of Triticale

Plants, 2020
In agriculture, the bio-stimulating properties of laser light increase the yielding capacity of crop species. The experiment aimed to determine the pre-sowing effect of irradiation time with laser He-Ne red light of triticale grains (×Triticosecale Wittm.

Effect of Phytochrome Deficiency on Photosynthesis, Light-Related Genes Expression and Flavonoid Accumulation in Solanum lycopersicum under Red and Blue Light

Cells, 2022
The effect of red (RL, 660 nm) and blue (BL, 450 nm) light on phy mutant tomato plants was studied. The rates of photosynthesis (Pn) and transpiration, the efficiency of the primary photochemical processes of photosynthesis, the contents of flavonoids ...

670 nm light mitigates oxygen-induced degeneration in C57BL/6J mouse retina [PDF]

, 2016
BACKGROUND Irradiation with light wavelengths from the far red (FR) to the near infrared (NIR) spectrum (600 nm -1000 nm) has been shown to have beneficial effects in several disease models.

Filtering Light-Emitting Diodes to Investigate Amber and Red Spectral Effects on Lettuce Growth

Plants, 2021
Red and blue light are the principal wavelengths responsible for driving photosynthetic activity, yet amber light (595 nm) has the highest quantum efficiency and amber-rich high pressure sodium lamps result in superior or comparable plant performance. On

Eccentric Ellipsoidal Red Giant Binaries in the LMC: Complete Orbital Solutions and Comments on Interaction at Periastron [PDF]

, 2012
Modelling ellipsoidal variables with known distances can lead to exact determination of the masses of both components, even in the absence of eclipses. We present such modelling using light and radial velocity curves of ellipsoidal red giant binaries in ...

The Morphological Responses of Calendula officinalis L. “Radio” to the Foliar Application of Benzyladenine and Different Light Spectra

Agronomy, 2021
Pot marigold is a valuable medicinal plant with great decorative value. Three combinations of light (white (W)—170 μmol m−2 s−1, white + blue (W+B)—230 μmol m−2 s−1, white + red (W+R)—230 μmol m−2 s−1) were used to analyse the influence of a diversified ...
