Abstract
In order to obtain better bio-process control (e.g. for plants in horticulture) it is necessary to have more insight in the response of the organism to its micro-environment.
In this paper it is shown that the air flow pattern and the imperfect mixing of the air create gradients in the micro-climate.
Gradients of temperature influence leaf temperature and plant processes. 3-Dimensional temperature distribution around a plant was measured and a method was developed to visualise the gradients.
State-space models of dynamic temperature response (air and leaf temperature) were identified using mathematical identification techniques: R2 -values of up to 99% were obtained.
