Analysis of the nature of interference between plants of different species. I. Concepts and extension of the de Wit analysis to examine effects

Abstract

Both competitive and non-competitive processes may strongly influence the growth of plants in a multispecific community, though the latter, particularly in experimental studies, are often overlooked. A method of analysis, based on the principles of the de Wit model, is suggested which may enable . the factors involved in both competitive and non-competitive aspects of interference between species to be identified.
