email-banner-header-template-960x220-kopieThe planet will need to feed 10 billion people by 2050. Global feed crop demand is expected to double by 2050 due to the growing world population. In addition, seasonal droughts and climate change will require healthier, smarter, more resilient plants. If you expect to lead in feeding the world, there’s only one way to get it right. Grow the perfect seed.

A New Focus on Photosynthesis

The 13C values of the CO2 is a fast indication of water-use efficiency (WUE) and plant response to drought. Imagine determining 13C photosynthetic discrimination of crop plants instantly. Isotope Ratio Infrared Spectrometry (IRIS) speeds up the process. The Thermo Scientific™ Delta Ray™ IRIS can perform accurate and precise, continuous, in-situ monitoring of isotopologues of trace gases at ambient concentration.

IRIS can be integrated into a plant chamber to detect rapid changes in the metabolism of a plant. You’ll be able to measure the impact of different plants species on the oxygen isotopic signature of atmospheric CO2 under varying environmental conditions. This is important for an accurate estimation of CO2 fluxes in terrestrial ecosystems based on 18O in CO2.

How It Works

IRIS can simultaneously measure the CO2 going in and out of the plant chamber: CO2 concentration as well as 13C and 18O isotope signatures. In the drying process, 13C significant changes are already visible after 24hrs.

IRIS provides continuous, feature-rich data for plant research. The carbon isotope ratio 13C -CO2 and oxygen isotope ratio (18O -CO2) of atmospheric carbon dioxide can be used to partition the gross fluxes of CO2 in terrestrial ecosystems, such as plant respiration, soil respiration and plant assimilation. The characteristic 13C value is modified by plant metabolism and photosynthesis.

The 18O is affected by the oxygen exchange between the molecules of CO2 and H2O stemming from different water pools. Similar measurements could, for example, be used to determine the efficiency of plants in phenotyping, studying the impact of elevated CO2 concentrations in a future climate or even exchanges at ecosystem level.

It’s the exacting process of producing smarter plants. Faster.

Observe rapid changes in plant metabolism by simultaneously monitoring carbon and oxygen isotope ratios of carbon dioxide under varying ambient conditions in a plant chamber. This offers you a totally innovative, non-destructive approach to whole plant physiology and processes that shorten production time and dramatically increase your potential for global seed output.

We’ve exponentially reduced the time for perfect seed development. With traditional methods, the changes in plant canopy were visible after four days. With IRIS, 13C changes are already visible in 24 hours.
