Potential Allelopathy In Different Tree Species

Reference Type
University Outreach Publication

Allelopathy is a significant tree health care issue. Allelopathy is the chemical modification of a site to facilitate better tree growth, and control ecological volume and essential resources. The proportion of allelopathy within each species’ interference effect is highly variable depending upon the site, species, and individual. The table below attempts to list trees in three broad categories of allelopathic effect: strong, moderate, and slight.

The table below has been prepared from the research literature to show relative and potential allelopathic effects of a given tree species. The relative ranking of species are based upon the completeness of the allelopathic literature, growth strategies of the species, species successional position, and conjecture of the author. At this point, not all the species listed have been shown to have measurable and demonstrable allelopathic effects in a landscape environment, but each one has been shown to have the chemical potential to be considered allelopathic.
