Are the common assimilate pool and trophic relationships appropriate for dealing with the observed plasticity of grapevine development?
The results of this study suggest new formalisms for increasing the ability of models to take plant plasticity into account. The combination of an ecophysiological model for morphogenesis taking environmental signals into account and a biomass driven model for organogenesis and biomass allocation taking the topological distances between the sources and the sinks into account appears to be a promising approach. Moreover, in order to simulate the impact of agronomic practices, it will be necessary to take into account the non-trophic determinants of plant development such as hormonal signaletics.
Adherence to three of the prescribing indicators increased after the introduction of decentralized drug budgets. Workplaces with a public employer showed greater adherence to two of the prescribing indicators than private sector workplaces.
