Insect and microtine rodent herbivory (defoliation and branch clipping, respectively) were simulated in stands of the deciduous Vaccinium myrtillus L. and evergreen V. vitis-idaea L. Rhizome connections around the treated plots were either left intact or severed. Recovery in the plots was monitored for two growth seasons, from 1991 to 1992. It was hypothesized that the evergreen V. vitis-idaea would suffer more from the simulated herbivory treatment than V. myrtillus, but that severing the rhizome connections would decrease recovery of both species, because clonal integration is disrupted and wounding may have a harmful influence on growth. After two growth seasons, recovery was complete from simulated herbivory in V. myrtillus, whereas the new dry biomass was reduced slightly (22 – 37%) or significantly (49%) compared with that of the control in V. vitis-idaea. Rhizome severing reduced the growth of the branches and ramets and the aboveground dry biomass by 34% compared with that of the unsevered control in V. myrtillus. In the evergreen V. vitis-idaea, severing slightly reduced growth, the effect being significant only in the clipped treatment. The results suggest that the deciduous V. myrtillus recovers more rapidly from simulated herbivory than the evergreen V. vitis-idaea. Rhizome severing is more detrimental to the growth of V. myrtillus, but less detrimental to recovery from simulated herbivory. Sexual reproduction decreases more in V. vitis-idaea than in V. myrtillus after damage. Key words: compensation, growth form, herbivory, rhizome severing, Vaccinium

Effect On Growth

This study examined the importance of clonal integration on the growth and mortality of a tropical dune plant, Ipomoea pes-caprae L. (Roth), in response to two stresses: sand burial and defoliation. Sand burial and artificial defoliation treatments were applied to one shoot on daughter ramets, some of which were connected to other ramets and some of which were not connected to other ramets. Sand burial significantly enhanced both stem growth and leaf production of the buried shoots, both for connected and unconnected ramets. Defoliation decreased stem growth of shoots other than the defoliated shoot, but only for unburied ramets. Defoliation also had a greater negative effect on growth of other shoots on connected ramets than on unconnected ramets. At the level of the entire ramet, burial stimulated both stem growth and leaf production for connected ramets, but not for unconnected ramets. These results support the hypothesis that physiological integration between ramets mediates the response to both sand burial and defoliation in Ipomoea pes-caprae.
