  • Measurement of Circadian Gas Exchange Dynamics in Arabidopsis thaliana

    Dr. Alex Webb and Dr. Antony Dodd (Cambridge University (UK), Department of Plant Sciences) and PP Systems have developed a unique gas exchange system for use with Arabidopsis. The custom system is being used as part of a program to dissect the architecture of the signal transduction networks that regulate circadian rhythms of stomatal aperture and photosynthesis. Since this is being addressed ...

  • Stability and accuracy of CIRAS-2 Water Vapor (reference humidity): control option 1

    Summary Rapid large-scale fluctuations of carbon dioxide and water vapor, although unnatural and artificial in the plant world, are desirable attributes for gas exchange systems from a sampling efficiency standpoint. As PP Systems’ benchmark IRGA system for gas exchange and photosynthesis research, CIRAS-2 was designed for and expected to have exceptional response times to ...

  • CIRAS-2 Export function-simplified data format with numerical and graphical data views

    Perhaps some of the most exciting moments for CIRAS-2 Portable Photosynthesis System users come when the time arrives to view meaningful data sets. What many new users will not realize is that they have the option of viewing these data in two formats: raw CIRAS-2 format (.dat) and a much streamlined Export format (.tab). Both formats easily and automatically import and parse into spreadsheet ...

  • Compost science journal of advocacy and foresight

    SEVERAL months ago, I started on a journey through the pages of Compost Science, beginning with the Spring, 1960 inaugural issue. I was confident that I could whip through the articles and news items in the several hundred issues of the magazine between 1960 and 2009, and be prepared to write this article for BioCycle’s 50th Anniversary Commemorative Edition. Granted, there were interruptions, ...
