Abstract :
A functional-structural model of winter oilseed rape (WOSR) has been developed to study plant morphogenetic plasticity, i.e. how processes of morphogenesis are adapted in response to environmental constraints. The phyllochron (time between emergence of two successive leaves) is one of the variables sensitive to environment. The aim of this article is to use model sensitivity analysis to quantify the impact of an increase or a reduction in phyllochron on plant growth and source/sink functioning.
