A Six Chamber Individual Plant Microenvironment Cabinet
ABSTRACT A facility for the simultaneous and continuous monitoring of photosynthesis, respiration and transpiration of a series of individual plants for a wide range of environmental conditions was designed and the limitations discussed. Temperature can be con-trolled from -7 °C to 30 °C and light intensity varied from 0 to approximately one third of the total photo-synethetically active solar radiation. Six similar micro-environment chambers facilitate rapid assessment of the usually large variation of gas exchange ratio exhibited in plant populations.
