Abstract	We conducted two experiments that investigated how the method and location of artificial defoliation influenced growth, reproduction, and allocation in canola, Brassica napus. In one experiment, 0%, 25%, or 50% of leaf area was removed by cutting circular holes at three possible locations: concentrated at either the base of leaves or at their tips, or dispersed throughout leaf blades. Plants fully compensated for such damage; reproduction and allocation were unaffected by either defoliation intensity or wound location. In a second experiment, we again initiated three intensities of defoliation: non-damaged plants served as controls, while others had 25% or 50% of their leaf areas removed. The method of removal in the second experiment consisted of cutting either multiple, similar-sized, circular holes or single, contiguous patches of a leaf blade. At the highest defoliation intensity reproductive output and allocation were significantly less in plants treated with the former method than the latter, even though an equivalent initial amount of leaf area was removed in both treatments. We conclude that simulated herbivory studies must account for not only how much of the plant is damaged, but also the pattern of leaf damage itself, since both factors contribute to a plant’s physiological and ecological responses to grazing.
