Abstract
Photothermal deflection is a sensitive technique for detecting very low concentrations of trace gases, such as NH3, C2H4 and CO2. These gases can have an important influence on the ecosystem of plants. To get a better understanding of this influence it is desirable to measure local concentrations in the surroundings of plants. These local measurements make it possible to determine the activity of the different parts of the plants. For example, C2H4 exhaust in leafs and stems [1], CO2 and H2O emission through stomata, and NH3 emission in barleyplants [2] can be measured.
