based Interactive Modelling Platform – and to write models in the rule-based
programming language XL (see www.grogra.de). Particularly, it is open for M.Sc. and
Ph.D. students in Applied Computer Science, Botany, Agriculture, Horticulture
or Forest Science with focus on information processing and modelling, and also

Climate change will affect various aspects of the wine
industry and consequently challenge the sustainability of grape production.
However, little work has been done on quantifying the response of berry
composition to climate change. Process-based models may fill this gap by
integrating berry development and quality formation with whole plant status and
environmental factors. This ongoing research project provides a novel approach
for incorporating whole plant development and berry development via xylem water
potential and phloem carbon concentration.

The shade avoidance syndrome (SAS) is one of the best-studied forms of
plant phenotypic plasticity, and several studies have showed that SAS increases
performance when competing for light with plants that do not show SAS. However,
it is unknown how natural selection could have acted on these plastic traits.
With a virtual plant model of Arabidopsis
thaliana we study the effect of specifically the petiole shade avoidance
responses on the performance of plants competing for light. The plant is
composed of small organ parts (e.g. petiole and the tip or base of the lamina),
resulting in all parts being able to perceive signals and respond independently
of each other. By also separating the responses in separate factors we can
study the responses in detail, and thus get a better understanding of how
phenotypic plasticity as traits could have evolved in time.

Unlike food
crops and vegetables in which biomass production is the main interest, in
ornamental crops morphological traits are also very relevant for economic
benefit. Although descriptive models have been developed for ornamental crops
to predict morphological traits such as plant height, number of leaves and
flower size, there is a demand in predicting morphological traits that are
relevant for ornamental quality, through more mechanistic methods for better
understanding the physiological control of plant morphology and optimizing
ornamental crop production. Functional-structural plant models (FSPM) simulate
plant structural development as governed by physiological processes and include
visual 3D output of plant phenotype. Lily was chosen for this case study due to
its importance in ornamental crop market. A lily FSPM will be developed and
used to optimize production in terms of morphological traits in relation to
light management and plant density.

Climate change
will modify the interactions between microclimate and plant architecture and
physiology by changes in local temperature, CO2 concentration and
light. As these interactions strongly influence crop yield, understanding these
modifications and deciphering the involved key mechanisms are an important
issue in the context of food security. To reach this goal, we aim to develop a
hybrid FSP-SVAT model that could be used to investigate crop responses to such
changes. Data for model calibration will be collected in a FACE experiment near
Tsukuba, Japan.

Plants grow up
competing over resources in ever changing environments, being able to react to
both competing neighbours and other environmental changes is vital to their
survival. The growth-defence trade-off is one example of a dynamic system in
which plant responses to light competition and insect herbivory interact on a
four dimensional scale. Another example is plasticity in root architecture in
response to neighbours or nutrient levels and distributions, the mechanisms
driving root plasticity are still a mystery. Both these systems offer a range
of opportunities for three dimensional plant modelling.

In the apple
branch, assimilates are carried from the sugar synthetizing organs (sources) to
other developing or storage organs (sinks). A sugar transport model for the
carrier branch of apple was conceived and built as a Functional-Structural
Plant Model using the GroIMP modeling platform. This model was based on water
and sugar fluxes in the phloem and the xylem. In this presentation we will
discuss how the model could be further parameterized to adjust it using data of
observed growth kinetics of apple tree organs.
