Few users of plant growth chambers are familiar with the fresh air intake and exhaust ports. Identified below, the fresh air intake allows the operator to manually adjust the rate at which fresh air is introduced into the chamber. The threaded collar is often located on the front of the chamber’s machine compartment and can be adjusted from fully closed (no fresh air) to fully open to allow maximum air exchange. See image below, left:
Air exchange is important in growth chambers to avoid CO2 deficits:
If you intend to use your plant growth chambers or rooms for tissue culture research, it is important to note that your chamber may not be well suited for tissue culture experiments in petri dishes. Should you place petri dishes in your plant growth chamber or room that features either a horizontal or downward airflow design - you may experience condensation on the underside of the lid of the petri dish. Below is a photograph of a plant growth chamber with horizontal airflow that is improperly being used for tissue culture research:
The Agiculture and Agri-Food Canada (AAFC) Research and Development Centre in Morden, Manitoba leads research in six areas:
A distinctive feature of the Morden facility is that it is a state-of-the-art Plant Pest Containment (PPC 3) facility, which is the highest quarantine level for virulent diseases.
On June 21, 2017 delegates from the International Conference on Arabidopsis Research (ICAR) toured the Donald Danforth Plant Science Center (DDPSC) in St. Louis.
Founded in 1998, the DDPSC is a world class facility home to 175 scientists and 20 Principal Investigators. Major research areas include:
Studying Epiphyte Contribution to Global Transpiration in Controlled Environments at University College Dublin
Dr. Sven P. Batke, IRC Research Fellow at the School of Biology and Environmental Science is utilising University College Dublin's plant growth chambers and plant sensory technologies to test how environmental variables such as temperature, light and CO2 impact the transpiration of tropical epiphytic plants. Below are several photos of epiphytes in growth chambers being exposed to different climate regimes as well as sensory devices used for the research investigation:
University College Dublin Project Investigates Resilience in Grasses Under Future Climatic Conditions
See you at the upcoming meeting of the Committee on Controlled Environment Technology and Use, April 9-12, 2017. The meeting is taking place in Monterey, California at the Asilomar Conference Center in Pacific Grove. It promises to be an educational and informative gathering. NCERA-101, NCR-101 is a committee of the USDA organized to help plant scientists understand how to use controlled environment technology effectively and consistently.
The objective of this blog is to provide insight on the technologies associated with plant growth chambers around the world by showcasing their usage in universities, institutes and other research centers of excellence.
The blog draws upon the work of clients and other users of controlled environment equipment, Conviron subject matter experts and Conviron’s long history as the world’s leading manufacturer of controlled environments.
