Glasshouse rose production

The chief objective of this STW- and PT-funded project is to improve the prediction of bud break and subsequent quality and quantity of the flower crop in the Dutch cut-rose system.


Two types of activities are being pursued to achieve this objective: Firstly, carefully designed greenhouse experiments are conducted in close consultation with participating rose growers, to ensure comparability between experimental results and conditions encountered at the growers’premises. In a further set of experiments (conducted in 2008), the influence of the source-sink ratio as well as of specific climate parameters (temperature) on bud fate (breaking and further development) will be investigated. The second activity consists in the creation of an FSPM of cut rose, which integrates information on the architecture of the cut-rose system with greenhouse climate data. Data sources for modelling will be both own experiments and the rich literature on this subject.

Three main types of models are envisaged as potential outcome of the project: Firstly, a decision-support tool for users, which serves prediction of shoot quality and quantity in a specific glasshouse setting; secondly, an extensible platform for research on rose growth, which at the same time could be used as a tool for improved experimental design ("vlab"); and thirdly, an interactive visual instruction tool for workers, simulating the effect of direct manipulative interaction (cutting, bud removal, pruning).


The PhD project started in March 2007 and ended in March 2011. The Postdoc project started in May 2007 and ended in June 2010.
