Correlation between dynamic tomato fruit-set and source-sink ratio: a common relationship for different plant densities and seasons?
BACKGROUND AND AIMS It is widely accepted that fruit-set in plants is related to source-sink ratio. Despite its critical importance to yield, prediction of fruit-set remains an ongoing problem in crop models. Functional-structural plant models are potentially able to simulate organ-level plasticity of plants. To predict fruit-set, the quantitative link between source-sink ratio and fruit-set pr...
متن کاملRhythms and alternating patterns in plants as emergent properties of a model of interaction between development and functioning.
BACKGROUND AND AIMS To model plasticity of plants in their environment, a new version of the functional-structural model GREENLAB has been developed with full interactions between architecture and functioning. Emergent properties of this model were revealed by simulations, in particular the automatic generation of rhythms in plant development. Such behaviour can be observed in natural phenomena...
متن کاملA Functional-Structural Plant Model--Theory and Applications in Agronomy
Functional-structural plant models (FSPM) simulate plant development and growth, usually accompanied with visualization of the plant 3D architecture. GreenLab is a generic and mechanistic FSPM: various botanical architectures can be produced by its organogenesis model, and the plant growth is governed by the competition on biomass among growing organs. A distinguished feature of GreenLab model ...
متن کاملOscillations in Functional Structural Plant Growth Models
The dynamic model of plant growth GreenLab describes plant architecture and functional growth at the level of individual organs. Structural development is controlled by formal grammars and empirical equations compute the amount of biomass produced by the plant, and its partitioning among the growing organs, such as leaves, stems and fruits. The number of organs initiated at each time step depen...
متن کاملFruit removal increases root-zone respiration in cucumber.
BACKGROUND AND AIMS Many attempts have been made to avoid the commonly observed fluctuations in fruit initiation and fruit growth in crop plants, particularly in cucumber (Cucumis sativus). Weak sinks of the fruit have been assumed to result in low sink/source ratios for carbohydrates, which may inhibit photosynthesis. This study focuses on the effects of low sink-source ratios on photosynthesi...
