Allelopathy refers to both harrnful and beneficiaI biochemical interations among all types of plants, including microrganisms. Inumerable crop and weed species have been reported to cause an inhibitory effect on the growth of other plant species, which is called allelopathy. Chemicals compounds with allelopathic potential are present in many plants and in many organs, including leaves, flowerS and fruits. Under certain conditions, these compounds may be released into the environment in sufficient quantities and with enough persistence to affect a neighboring or successional plant. In field situations it has been shown that the release of allelochemicals occurred by exudation from living roots and decomposition of plant residues. Evidence for allelopathy has accumulated in the literature over many years, however, little information is available about the allelopathic potential of plants.
