摘要

Compensatory growth for defoliated plants is an issue still debated in literature, due to methodological weakness and lack of knowledge about its occurrence. In a green-house experiment, we applied three types of defoliation on Elytrigia juncea, a Poaceae species dominating costal foredunes. Responses to the different combinations of intensity and frequency of defoliation were assessed by measurements of final biomass of target species. Relative growth rates in height and number of leaves were also calculated, enable us to assess more accurately compensatory growth. An important growth stimulation was pointed out two weeks after a severe cut, and was still visible over the course of the experimentation without being able to induce overcompensation of growth. The occurrence of compensatory growth was pointed out only when plant tissues removed by cutting were added.
