Definition

Glossary of "Ecology (6th ed.)" by Krebs (2009)

  • organisms that alter the surrounding chemical environment in such a way as to prevent other species from using it, typically with toxins or antibiotics.

Glossary of "Plant Biology (1st ed.)" by Graham et al. (2003)

  • A type of plant competition in which one plant species produces chemicals that inhibit growth of individuals of the same or different species growing near it.

Glossary of "A Botanist's Vocabulary" by Pell & Angell (2016)

  • Phenomenon in which a plant secretes compounds that interfere with the growth, reproduction, or continued survival of other plants around it; e.g., black walnut (Juglans nigra).

Rizvi et al. (1992)

  • Allelopathy (rootwords: allelon and pathos) is derived from the Greek allelon, 'of each other', and pathos, ' to suffer'; hence it means: the injurious effect of one upon another. The term denots that body of scientific knowledge which concerns the production of biomolecules by one plant, mostly secondary metabolites that can induce suffering in, or give benefit to, another plant. The phenomenon could also be considered as a biochemical interaction among plants. The concept suggests that biomolecules (specifically termed allelochemicals) produced by a plant escape into the environment and subsequently influence the groowth and development of other neighbouring plants. The subject not only deals with the gross biochemical interactions and their effects on physiological processes but also with the mechanism of action of allelochemicals at specific sits of action at the molecular level.
  • The term 'allelopathy' was coined by Molish in 1937 and his definition referred to both the detrimental and beneficial biochemical interactions among all classes of plants, including microorganisms. This has led Rice (1984) to give the following definition of allelopathy: 'any direct or indirect harmful or beneficial effect by one plant (including microorganisms) on another through production of chemical compounds that escape into the environment'.
