Modelling winter oilseed rape carbon accumulation during the reproductive phase

Abstract

Actes sur CDROMInternational audienceThe observed decrease in oilseed rape conversion of intercepted radiation efficiency during reproductive phase could be due to leaf falling off, pod senescence or to the specific energy cost of oil production. In reason of its interest in modelling, we tried to identify and quantify the processes really involved in this decrease, for different genotypes under contrasted nitrogen fertilisations
