Magnetic resonance imaging of plants: plant water status and drought stress response
This Thesis presents an approach for the study of plant water balance during drought stress, using a combination of in vivo NMR experiments and computer simulations. The ultimate aim is the interpretation of the NMR parameters in terms of physiologically relevant characteristics, such as cell dimensions and membrane permeability. Especially the lat...
Water uptake in crop growth models for land use systems analysis. I. A review of approaches and their pedigrees
Descriptions of crop water uptake/transpiration are of widely varying complexity and employ considerably different approaches. This paper examines simple approaches that could be used in crop growth simulation models for application in land use systems analysis. Many apparently conceptual differences stem from different interpretations of averaged ...
Afstemming biotische responsmodules DEMNAT-SMART/MOVE
In 1995 is door vertegenwoordigers van RIVM, RIZA, EC-LNV, IBN- en SC-DLO, CML overlegd over de afstemming van de modellen gebruikt bij ecologische voorspelling. Een onderdeel daarvan omvat de te verwachten veranderingen in standplaatsfactoren (biologische responsmodules). In dit rapport worden de twee responsmodules SMART-MOVE en DEMNAT met elkaar...
Water uptake in crop growth models for land use systems analysis: II. Comparison of three simple approaches
This paper addresses water uptake by roots as calculated in summary crop growth models for use at the land use systems level. Simple comparative exercises were carried out using three models. The results show considerable differences in daily and cumulative water uptake. One model calculates moisture changes for subdivisions of the root zone, even ...
Towards a simple integrated model for the re-wetting of nature reserves
Validity of Ellenberg indicator values judged from physico-chemical field measurements
The relationship between mean Ellenberg indicator values (IV) per vegetation relevé and environmental parameters measured in the field usually shows a large variation. We tested the hypothesis that this variation is caused by bias dependent on the phytosociological class. For this purpose we collected data containing vegetation relevés and measure...
