Leaf physiology
The condition of a plant and its reaction to environmental conditions (drought stress, air pollutants) can often be perceived on the leaves at an early stage, but are often only actually visible after a long time. Such changes can be recorded promptly using parameters such as the chlorophyll content of the leaves, stomatal conductivity, CO2 content or oxygen partial pressure. This data is not only used to determine the current condition of a plant, but can also significantly increase yield as a basis for optimized cultivation.
