The effect of mycorrhizae and competition on plant growth
Plants grown with a conspecific were 25% shorter than those grown
individually (Fig. 4,
F1,174=105, p<0.001), confirming that the
plants were competing with each other. Mycorrhizae did not alter height
(Fig. 4, F1,174=1.54, p=0.216). We did not find that
mycorrhizae promoted size dimorphism when the plants were grown in
competition (F1,100=2.30, p= 0.133).
