A new way to account for the effect of source-sink spatial relationships in whole plant carbon allocation models .

Reports that, to improve source?sink relationship based carbon-allocation models, the basic proportional model was extended to account for a well-known effect of individual source to sink distances. Development of the model, which was parameterized and evaluated on the empirical allocation matrix of the ECOPHYS model; Methods; Results; Discussion of the possibilities of generalization and practical use of the model.
