Climate change causes greenhouse gas emission by plants
|
Global warming seems to be self-sustaining by making plants emit the potent greenhouse gas, methane (CH4), while simultaneously reducing their assimilation of CO2. This conclusion was obtained by Mirwais M. Qaderi and David M. Reid from University of Calgary, Canada, who tested methane emission and several growth parameters from six crop species grown under various environmental conditions. An increase in temperature from 24/20 °C (day/night) to 30/26 °C led to a 15% increase in methane emission, while the effect of water stress, which will accompany global warming in many regions, increased emission of the greenhouse gas by 22%. The figures are average measurements from faba bean, sunflower, pea, canola, barley and wheat. Under ambient conditions the six crops emitted between 85 (barley) and 170 (pea) ng methane per g dry weight per hour. At the same time, the higher temperature caused CO2 assimilation to decrease 27%, while water stress reduced CO2 assimilation by 31%. The researchers will now investigate how elevated CO2 levels affect methane emission in order to get a better picture of how global warming can turn plants into greenhouse gas contributors.

SPPS will now change to a system in which the membership fee for the following year is collected beforehand. That is why we start reminding you about the SPPS membership fee of 2010 already in October. You will get an email with a link to your membership pages so the renewal of the membership will be easy. On the Members section of the SPPS homepage you can renew your membership if you are already a member or you can sign up to become a member of SPPS. Signing up is easy and your membership will come into effect as soon as we have received your payment.
The membership fee for 2010 is only 30 € or 150 € including a full years subscription to our international journal Physiologia Plantarum. Additional benefits include:- Free SPPS newsletter four times a year
- Discounts on registration fees to SPPS Congresses
- Possibilities of obtaining travel grants
- An electronic membership directory
You can see your options as a member of SPPS on the Members section on the SPPS homepage.
