This happens in a gastight apparatus, the Biobox, which controls the temperature, air humidity, light, and the concentrations of CO2 and oxygen in the atmosphere. The exchange rates of CO2 and oxygen are measured all the time. This trial will run for about 12 more days, after that time the CO2 in the Biobox will be replaced by the stable isotop 13CO2. After a while probes will be taken and parts of the metabolite of the plant will be analysed. You can look at a new picture every 10 minutes (pic_10min.jpg). Pictures are saved every 6 hours (pic_6hxxxx.jpg). screen.jpg is a screenshot of the control programm and gives an overview of the conditions inside the Biobox. Biobox.box is an ASCII-file which contains all the data of the environment and gas exchange rates. It has to be processed with some kind of spreadsheet programm. Best regards, Carsten Richter .
