Abstract:
A portable field system for simultaneous measurement of transpiration and CO2 exchange from leaves of fruit trees is described. CO2 concentration is measured by means of infra-red gas analysis, using small gas samples collected in syringes. Methods for analysing small gas samples are compared. The leaf chamber described can also be used in a conventional laboratory open gas-exchange system, its small volume permitting measurement of very rapid changes in gas exchange in response to experimental stimuli.

During photosynthesis, plants acquire the necessary carbon dioxide and release the produced oxygen back into the atmosphere. Openings in the epidermis of plant leaves is the site of this exchange of gasses. A single opening is called a stoma—derived from the Greek word for “mouth.” Stomata open and close in response to a variety of environmental cues.

Understanding and evaluating diffusion and perfusion is critical in assessing a patient's respiratory and circulatory health. These processes play key roles in maintaining the body's internal environment, ensuring that tissues receive adequate oxygen while waste products are efficiently removed.
