Table 2.
anova results for Lower Peninsula 2,4-D sensitivity experiment. (A) length gained and (B) length at a treatment of 2,4-D relative to length at the control (Length treated/Length control). Data were square root transformed. Nesting variables appear inside parentheses, and × indicates interaction terms
