Relationships between interbranch distance and diameter of the parent root. The lines represent the trends between these variables (calculated by the ‘LOESS’ smoother of R). The three graphs illustrate the three cases that were observed for the different species: decrease of interbranch distance with parent root diameter (A: Chelidonium majus); independence (B: Silene vulgaris); and slight increase (C: Melilotus albus).
