Allelopathic, Herbaceous, Vascular Hydryphytes
Chemistry and Biochemistry
A review of the literature since 1970 shows 67 genera and 97 species of herbaceous vascular hydrophytes reported to be allelopathic. The most frequently cited genus is Eleocharis with 11 included species. Lettuce is the most frequently used target plant. Comparison of lettuce and Lemna minor as bioassay target plants shows L. minor to be the more selective plant assay. Nuphar lutea and Nymphaea odorata are highly inhibitory toward both lettuce seedling radicle growth and L. minor frond production. Alkaloids from Nuphar lutea are being re-isolated to examine their allelopathic potential. Allelochemicals present in Nymphaea odorata are extracted by 95% ethanol, and are ethyl acetate soluble.
