Abstract:
Analysis of small-scale distribution may allow allelopathic interaction among plant species to be distinguished from competitive interaction. If all environmental factors except slope are uniform, allelopathy produces spatial asymmetry in the association with a hypothetical receptor species and the corresponding hypothetical emitter species in the neighborhood of the latter. The interaction betweenRumex obtusifolius and the meadow speciesLolium perenne, Poa pratensis, Dactylis glomerata, andTrifolium repens is analyzed by way of example.
