  • a Values with different superscripts differ significantly by Student's t-test (α = 0.05). Data were arcsine transformed prior to analysis. Contrasts for compatible vs. incompatible crosses used directed t-tests (Rice and Gaines 1994), while all other contrasts use symmetrical tests. Probabilities were corrected for multiple tests using the sequential Bonferroni technique (Rice 1989).
