Appendix B. A table showing th effects of simulated herbivory on hexaploid American plants.

Table B1. The effect of simulated herbivory on relative height growth rate (RhGR) during day 1–20 and day 41–138, final stem height, area of a leaf, specific leaf area, stomatal conductance, inflorescence biomass, and number of vegetative offspring of hexaploid American plants of Solidago canadensis. Means are given ± 1 SE for non-transformed data, and ± upper SE/lower SE for log- and square root-transformed data after back transformation.
