Root:shoot ratio of Pinus muricata. (a) Mean P. muricata root:shoot ratio, as influenced by interaction between P. muricata maternal seed family used and soil type. (b) Mean P. muricata root:shoot ratio, as influenced by interaction between R. occidentalis sporocarp and soil type (lab versus field). Means with different letters are significantly different from each other (p < 0.05) according to Tukey HSD post-hoc tests.
