Sink Limitation & SugarClim

Our research focuses on unraveling the processes of sugar beet (Beta vulgaris L.) yield formation. Sugar content in beets is influenced by the dynamic interplay between photosynthesis in leaves (source) and the transport of sugar from leaves to beet (sink). Further, several abiotic factors affect the assimilation and partitioning of carbon in the beet. Other studies suggested that the accumulation of carbohydrates is sink-limited from a not yet determined time in beet development. For optimizing sugar yield forecast, the understanding and quantification of these processes is essential, particularly under the impact of abiotic stressors such as drought, heat, and nutrient deficiencies. Therefore, we run diverse field and greenhouse trials.

 Our project fills critical knowledge gaps needed to enhance yield forecast modelling to future climate conditions, e. g. increased CO₂-concentration.
