Light Approaches to Speed up the Generation Turnover

The development of new plant varieties with advanced performance or an improved environmental adaptation is important to secure our food. To obtain new genetic recombinants or to introduce one or multiple target genes, plants need to be pollinated in a controlled way and seeds must be collected – best as fast as possible to keep […]

Why is LED Grow Light Purple?

Sure, by now we are all aware that LED light does wonderful things for plant growth. Plants grow quicker and healthier than under other, traditional lighting methods such as HPS, and if the LEDs are good, then even better than under natural sunlight. But why are they always purple/pink? All light sources contain a spectrum […]

The Effect of LED Grow Lights on Human Health

The rapid increase in the use of LED technology for horticultural lighting applications has also raised discussions regarding the potential human health risks compared to legacy lighting solutions. This is somewhat due to the differences in visual appearance (colour and intensities) of the light in such applications. At a high enough intensity, any type of […]

How do you spell light?

Characterizing spectral properties and calculating irradiances are everyday tasks for many researchers in the field of plant photobiology. Varying waveband definitions in use, different photoreceptors found in plants, let alone the difference between expressing light on photon or energy basis can make one’s head spin. To tackle this, a couple of publications and an application […]

Could one combine good plant growth light and at the same time prevent pest reproduction?

Plant growth and morphology can be modified with light quality, but could plant pests be affected too? For example narrow bandwidth UV-B light can be used directly and efficiently against the growth of powdery mildew fungi, as thorough investigations in a collaborative project by Cornell researchers and colleagues in Norway have shown. However, the UV-B […]

Studies related to plant secondary chemistry and plant-to-plant communication

Jarmo Holopainen, Professor of Applied Ecology from the University of Eastern Finland, Department of Environmental Science and his research group are doing multifaceted biological and ecological research. The research is related to biological and ecological effects of global change, plant-herbivore interactions, secondary chemistry of plants, biogenic volatile organic compounds and to formation and ecological effects […]
