Fig. 6. Relative seed weight (A) and relative seed oil concentration (B) as functions of relative post-flowering source–sink ratio in a number of experiments. The dashed lines show the theoretical slopes of 1 (full source limitation), and the horizontal dotted lines the slope of 0 (full sink limitation). The solid line in panel A indicates the model fitted to the data. RMSE = root mean square error of the model. Descriptions of experimental conditions of each data set are summarized in Table 1. Previously unpublished data sets Perez Alisedo and Ruiz, 1993; Dedominici and Ruiz, 2000.
