Summary of statistics used to test the influence of growth site (phenotypic plasticity) and seed source (ecotypic variation) on leaf size and shape in <i>Acer rubrum</i>.

Note.—Variables are grouped by relatedness to leaf dissection, tooth number, or leaf and tooth size. Two-way analysis of variance (ANOVA) used for all tests; ‘growth site’ and ‘seed source’ test for no differences in a leaf variable between the two sites of growth and among plants with different seed sources, respectively; ‘growth × seed’ tests for no differences in a leaf variable due to the interaction between growth site and seed source; outcomes indicating significant differences (P<0.05) are in bold.
