Why seedlings always grow towards the light
Scientists from the Carnegie Institution at Stanford University and Wageningen University, part of Wageningen UR, have discovered how cells in the stems of seedlings use blue light to grow towards the light. During earlier research it was discovered that the cells in the seedling stems responded to blue light used in the microscope. The scientists have now discovered how the blue light causes ...

Is Vertical Farming Here to Stay?
Farmers growing vertically, in a warehouse, say they can grow 100 times more greens per square foot than traditional farms. Videos and articles are popping up everywhere about new vertical farms opening. An article from Business Insider features a new farm called Bowery, located in New Jersey. Using LED lighting that mimics natural light and instead of soil, growing hydroponically, they are ...

Plant Morphology and Spectrum: How Plants Respond to Light Quality
Light is one of the most important factors for optimizing plant growth. Plants collect energy from light to make sugars and these sugars are used for the growth of roots, leaves, stems and flowers. Plants use light for both photosynthesis and to respond to the environment to optimize their growth. Light can be described as the visible portion of the electromagnetic spectrum which extends from ...

Lighting strategies for LEDs in greenhouse horticulture
The use of assimilation lighting in greenhouse horticulture has increased by 10% per year during the past decade, leading to a considerable increase in electricity consumption. LED lighting systems have a variety of advantages, ranging from their small size, high energy conversion efficiency to the option to emit specific wavelengths. In the EU project HI-LED, Wageningen UR Greenhouse ...

Common Pesticide Reduces Food Value of Algae
SILVER SPRING, Maryland (ENS) - Researchers with the NOAA National Centers for Coastal Ocean Science have identified negative effects of the commonly used herbicide atrazine on phytoplankton, the free-floating algae that form the base of the food chain for aquatic animals. Published in the current issue of the journal 'Pesticide-Biochemistry and Physiology,' the study indicates protein levels ...

The Role of LEDS in Speed Breeding
Some of the most important crops for feeding the ever-increasing global population include wheat and barley. In order to meet the future demand, scientists have a task of finding ways to improve efficiencies in breeding these and other, similar plant species. Typically, more than 10 years are needed to develop novel cultivars with an advanced agronomic performance. On one hand it is because ...

Major breakthrough on how viruses infect plants
CSIRO plant scientists have shed light on a problem that has puzzled researchers since the first virus was discovered in 1892 – how exactly do they cause disease? In a major breakthrough that helps us better understand how viruses cause diseases in plants – and potentially in animals and humans – Dr Ming-Bo Wang and Neil Smith of CSIRO Plant Industry have revealed a ...

NDVI and Your Farm: Understanding NDVI for Plant Health Insights
NDVI and Your Farm: Understanding NDVI for Plant Health Understanding your crops’ health status isn’t the easiest thing to do. Sure, you can use the “eye test”, and a number of foliar contact and direct measurement techniques. But, what if there was an easy, fast and efficient way to see the health of plants and their status and progress over time? That’s where ...

Helping quinoa brave the heat
Quinoa is a healthy food many know and love. As its popularity grows, more farmers are interested in planting it. However, the plant doesn’t do well in high temperatures, so plant breeders are trying to help. Many of the current methods for seeing if a quinoa plant is heat tolerant are time-consuming and expensive. Researchers, led by professor Kevin Murphy at Washington State University, ...

Light-emitting Diode Sole-source Lighting Effective in Bedding Plant Seedling Production
In northern latitudes, producers of bedding plants depend on supplemental lighting during the late winter and early spring growing seasons. Unfortunately, these peak times for young plant production are also the darkest. Researchers have determined that a minimum amount of photosynthetic light (daily light integral; DLI) is necessary to produce high-quality young plants in greenhouses. In ...

End-of-production LED Lighting Increases Red Pigmentation in Lettuce
Growing vegetables in greenhouses extends crop production seasons in northern latitudes, but the greenhouse environment is far from ideal for providing plants with optimal photosynthetic light. In fact, available photosynthetic daily light in greenhouses can be reduced by up to 50% or more by the structures' glazing material, superstructure, and shading. In northern latitudes, low light is ...

GM crops can thrive as climate warms
Genetically engineering photosynthesis in plants could take advantage of rising global temperatures and increased levels of carbon dioxide, US scientists say. They believe this could achieve much higher yields on the same amount of land and help to stave off the prospect of widespread hunger as human populations increase. Researchers at the University of Illinois report in the journal ...

Gas Sensing for Optimal Marijuana Medical Use Crop Growth
Following the legalisation of marijuana sale for medical use in 33 US states1 and Canada,2 marijuana sales have become big business. It is estimated that in 2020 US retail sales of marijuana will continue their rapid growth, from $15. 7 billion to $19 billion3 with suppliers struggling to keep up with demand. In Colorado alone, legal demand for medical use marijuana was exceeding 100 metric tons ...
