allelopathy, n. Bot.|æliːˈlɒpəθɪ|
[ad. G. Allelopathie (H. Molisch Der Einfluss einer Pflanze auf die andere—Allelopathie, 1937), f. Gr. ἀλλήλ- one another: see -o1, -pathy.]
The deleterious process by which one organism influences others nearby through the escape or release of toxic or inhibitory substances into the environment: usu. restricted to such interaction between higher plants.
1957H. Martin Chem. Aspects Ecol. ii. 11 It would seem unnecessary to go to the extreme of Molisch..who coined the word ‘allelopathy’ from the reciprocal influence of higher plants. 1961Symp. Soc. Exper. Biol. XV. 242 There is..a type of allelopathy which..follows from the movement of metabolic products from one species into another. Ibid. 243 Perhaps the term ‘allelopathy’ should be extended to include the manifold mutual effects of metabolic products of both plants and animals. 1974E. L. Rice Allelopathy i. 1, I feel that the current use of the term, allelopathy, should include any direct or indirect harmful effect by one plant (including microorganisms) on another through the production of chemical compounds that escape into the environment. 1982J. B. Harborne Introd. Ecol. Biochem. (ed. 2) viii. 212 In this case of allelopathy, as in most others, the toxin is effective against many but by no means all competing plant species. 1988New Scientist 7 July 54/1 The rhododendron also poisons the soil with short-chain aliphatic acids, deterring plant roots of other species—a phenomenon known as allelopathy.
Hence aˌlleloˈpathic a., pertaining to or of the nature of allelopathy; esp. designating a plant product having such toxic or inhibitory qualities.
1960Bot. Rev. XXVI. 414 The over-all growth of a plant undoubtedly is determined more by the proper balance of growth factors (space, light, water, mineral nutrients, etc.) than by allelopathic factors. 1984E. J. Kormondy Concepts Ecol. (ed. 3) iv. 139 This chemical results in the weaker filter feeder (Epischura) having an inhibiting, or allelopathic, impact on the stronger filter feeder (Diaptomus). |
