I notice your request for a list of C4 plants on the Bionet web site. Did you ever get a reply or link to this list as I am also interested to understand what plants make up this C4 pathway listing? Looking forward to your reply Thanks Mark Leivers Floranova Ltd. Registered office: Norwich Road, Foxley, Dereham, Norfolk. NR20 4SS. Registered in England, number 01370190.

To distinguish between C3 and C4 plants you have to provide either measurement of compensation point or do measurements of photosynthesis at 1% and 21% of O2 in sample air using any closed system for photosynthesis measurements (IRGA) like CIRAS-2 or TPS-2 from PP Systems Company (http://www.ppsystems.com). I hope that this will help.

Lethbridge and the entire region of southern Alberta boast some of North America’s most spectacular cultural and natural history sites. The area has a diverse range of ecosystems from native prairie, foothills, badlands, rivers, lakes and mountains, all under Alberta’s big blue sky. Nearby the Head-Smashed in Buffalo Jump Interpretative Centre, a UNESCO World Heritage Site, and Writing-On-Stone Provincial Park document the culture and history of the local native peoples. Waterton and Banff National Parks offer the breathtaking beauty and recreational opportunities of the Canadian Rocky Mountains. The cost of living is low and the quality of life is high.
