In this project a conceptual framework is made about different types of plant stress in a greenhouse cultivation. The aim is to get a better understanding of plant stress and to prevent the need for energy consuming actions when a plant is “out of balance”. What is plant stress? A plant strives for homeostasis: all chemical and physical processes are in balance with the environment. In a stress situation, a plant senses the change that disturbs the balance between plant and environment. The plant adapts to the new situation which leads to a new balance (acclimation). That means that stress can have a negative impact on the crop, but stress can also be beneficial. Crop and climate management both disturb the balance and steer the crop in the desired direction, which is considered as positive stress. The cultivation method “Next Generation Growing” aims for balances in crop and greenhouse. It is not always clear which actions lead to positive stress and which actions are negative for the crop. Monitoring plant balance or plant stress would be a helpful tool. But a lot is still unknown, like which plant processes should be monitored, what are critical values and what time period is needed for “a balanced crop”.
