Morphological, anatomical, and physiological changes of orchardgrass leaves grown under fluctuating light regimes
The physiological and anatomical adaptability of pastures growing under trees in silvopastoral systems can alter the efficiency of conversion of energy to dry matter (DM). This study was conducted to determine the effects of different fluctuating light regimes (from 24 to 100% transmissivity) on leaf physiology, morphology, anatomy, and structure of orchardgrass (Dactylis glomerata L.) in a ...

Impact of Phakopsora Pachyrhizi infection on soybean leaf photosynthesis and radiation absorption
Yield loss in soybean [Glycine max (L.) Merr.] due to soybean rust (SBR) (caused by Phakospora pachyrhizi Syd. & P. Syd.) has been associated with reduced radiation interception and reduced radiation use efficiency by green leaf area. The objective of this study was to determine the mechanisms involved in the SBR-induced reductions in radiation use efficiency by quantifying the effect of SBR ...

Full Spectrum Vs. Red/Blue Spectrum LEDs
What is the difference between Red/Blue vs. Broad “Full” Spectrum LEDs? Growers generally have two options when it comes to horticultural LED spectrums – “full spectrum” or “broad-spectrum”, which appears as white light; and “red/blue spectrum”, which can appear as purple or pink light. The red/blue spectrum LED luminaires are often referred ...

Demystifying Light Levels for Cannabis Grows
As more and more investors, opportunists and growers are jumping onto the green rush that is the cannabis industry right now there is also a big influx of folks who are learning as they go. Lighting is a major purchase for this industry as a big margin of growers still prefer the better climate control and security of growing indoors and even those who choose to grow in a greenhouse are finding ...

Maximize Yields with Smart Lighting Strategies: Using Metrics for a More Efficient Grow
There is a strong relationship between lighting and yield, as we know that with every 1% increase in light, there is a 1% increase in growth and yield. Measuring yield in your greenhouse is an important way to measure efficiencies and profitability, so you can better assess how your inputs affect overall yield and plant growth. In this article, we are going to overview the relationship ...
