Our aim is to promote gas exchange measurements of whole unscathed plants/shoots in controlled conditions. Measuring whole plants or attached shoots provides a unified picture, where macroscopic plant water relations, transpiration, photosynthesis, water conducting tissues in the plant and microscopic events in the guard cell signaling are all brought together – this is what happens in real plant growing in real field. Using multiple cuvettes simultaneously adds value, as it enables to measure several plants under similar conditions and thus, to get representative datasets.
