Figure 4

Effect of water stress (A), nutrient availability (B) and pure (C) and mixed (D, E) density on dry mass allocation to roots, stems, leaves and reproductive organs of Ceratocarpus arenarius plants derived from each dispersal unit morph (mean ± 1 SE). Only dry mass allocations ≥ 0.91% and standard errors ≥ 0.66% are shown. Different lowercase letters indicate significant differences in multiple range comparison among levels for all treatments of plants from the same dispersal unit morph (P < 0.05). DUa, dispersal unit morph a; DUc, dispersal unit morph c; DUf, dispersal unit morph f; H, high; M, moderate; L, low.
