Biological Activity of Allelochemicals
2009All plants produce compounds that are phytotoxic to another plant species at some concentration. In some cases, these compounds function, at least in part, in plant/plant interactions, where a phytotoxin donor plant adversely affects a target plant, resulting in an advantage for the donor plant.

Bioavailability of Allelochemicals in Soil
2008Abstract : The successful spread of the weeds Acroptilon repens (Russian knapweed, RK) and Centaurea maculosa (Spotted knapweed, SK) has been attributed to the exudation of allelopathic chemicals by their roots. RK releases 7,8-benzoflavone and SK releases (+/-)- catechin.

Evolution of Allelochemics in Angiospermae
1982Primitive angiosperms may owe their woody habit to a gymnosperm-type ancestry. Gymnosperms, in which, significantly, alkaloids are rare, possess the metabolic pathway sugar → shikimic acid → chorismic acid → phenylalanine → cinnamic acid → cinnamyl alcohol (Fig.

Ecological Relations (Allelochemicals)
1984Microorganisms, plants and animals live in a world of chemical signals. These signals, in most cases secondary products, are of special importance in ecology, i.e., the mutual relations between the different groups of organisms, which cause the formation of the characteristic communities of living beings in the forests, meadows, and deserts, in pools ...

Allelochemics as Systematic Markers
1982Life, as we know it, is inconceivable without hydrogen, carbon, nitrogen, oxygen, phosphorus, sulphur etc. The production of the heavier of these elements requires several billion years of “cooking” time in the interior of a star. The time lapse from the “Big Bang” to the final gravitational collapse of a universe, however, is, according to Einstein’s ...
