Die Stomata als Glieder eines schwingungsfähigen CO2-Regelsystems Experimenteller Nachweis an Zea mays L.

Using recording porometer techniques, evidence was produced for the existence of a regulatory system stabilizing the carbon dioxide concentration within the intercellular spaces of leaves. The guard cells function as effectors, and most probably also as sensors. Measurements by the cells of the carbon dioxide concentration and stomatal movement are two separate processes; the second requires auxiliary energy. The system reacts to disturbances after a time lag. This causes overshoot. Additional strong feedback may lead to stomatal oscillations which sometimes persist, or even increase in amplitude indicating insufficient damping.
