Abstract
A climate-controlled, field-portable, single-plant enclosure system is described. The system is capable of measuring the photosynthesis (PS) and transpiration (TS) of a single corn plant on a half-hourly basis to better than ±5% of typical PS values and ±16% of typical TS values. All data acquisition and climate control is aided by a microprocessor-based data acquisition system. Humidity is controlled and TS measured by absorbing transpired water on a column of CaSO 4; PS is obtained from required CO 2 injection rates. Both water vapour and CO 2 concentrations are kept constant and air temperature is maintained close to ambient by a water-to-air heat exchange system. At present, the system is capable of controlling to constant, user-selected CO 2 and water vapour concentrations. The system could be easily modified to study the effects of elevated CO 2 concentrations, levels of various pollutants, changes in air temperature, PPFD, and many other environmental variables.
