ANCOVA results.

Analysis of traits measured in the reciprocal sowing experiment. SM: seed mass (covariate); G: garden (fixed); Z: climatic zone (fixed); and P: population (random). The interactions between factors and the covariate (GxSM; ZxSM; and PxSM(Z)) were first tested in the ANCOVA model. These interactions were then removed from the model to test for factor effects, interactions between factors, and the covariate. As germination in all pots occurred between two rounds of observation in the Mediterranean garden, time to germination could not be analyzed for this garden (no variance). Significant results are in bold.
