CAM photosynthesis in orchids: unravelling the regulation of PEPC and developing a method for measuring mesophyll conductance

Phalaenopsis, like 7% of all vascular plants among which several important crop species for food, ornament and bioenergy production, has CAM photosynthesis. Different from C3 and C4 ...

Investigating the effect of far-red light on leaf photosynthesis to increase production

Application of light-emitting diode technology has opened opportunities to optimize light spectrum for crop production greenhouses and vertical farms, but also pointed to interesting aspects of far red light on photosynthesis in ...

Is there an optimal light recipe that suits CAM photosynthesis? 

Using a whole plant gas exchange chamber, it is possible to continuously monitor the four phases of CAM photosynthesis and study how different light recipes impact daily carbon gain. Combined with the recently acquired DUAL-PAM system that monitors both PSII and PSI operating ...

Development of a FSP model to determine dwarf tomato architectural ideotype for improved carbon assimilation in vertical farming

The aim of this project is to identify one or more architectural ideotypes of dwarf tomato plants that improve carbon assimilation in vertical farming. An existing Functional Structural...

Modelling dynamic leaf photosynthesis in wheat

In nature, photosynthesis of field crops depends on environmental conditions like temperature, humidity and irradiance. When these conditions are stable over time, the processes that control photosynthesis are stable as well. Examples of such processes are stomatal movement...

Calibration and validation of photosynthesis and growth model in the context of Functional-Structural Plant Modelling of dwarf tomatoes in vertical farming

This project forms a component of a broader initiative aimed at identifying the architectural ideotypes of dwarf tomato plants, which...

Low-cost porometer

A porometer is an instrument that measures stomatal conductance via the rate of water vapor diffusion out of a leaf. Porometers are relatively expensive instruments, but in principle, they can simply be built with low-cost humidity sensors. This project seeks to build, calibrate and validate a low cost porometer for use in future research...

Open source greenhouse and crop modelling for an open and collaborative research culture

Greenhouse and crop models are an important tool in the research aimed at improving greenhouse cropping systems. Such models can be used, for example, to evaluate how changes in the greenhouse environment influence the crop...
