Varietal Differences in Allelopathic Potential of Common Buckwheat (Fagopyrum esculentum Moench)

Abstract

The utilization of allelopathic plants has been receiving worldwide attention because it could reduce application of herbicides. Buckwheat is one of those plants with a high allelopathic potential. The genetic variability of allelopathic potential has been described in, e.g. rice, lucerne and wheat. The aim of the present work was to evaluate the influence of varieties on the allelopathic potential of common buckwheat. Three varieties of common buckwheat of different origins were tested. Varietal differences were evaluated through biotests with aqueous extracts of both fresh and dried plant parts of buckwheat (leaves, stems, roots). Varietal differences in allelopathic potential of common buckwheat were found in extracts from all plant parts. The strength of the allelopathic potential was dependent upon treatment (fresh or dried material) and conditions within the given year. Rutin, the main flavonoid of buckwheat, probably plays an important function in the allelopathic potential of buckwheat biomass and it is the possible reason of varietal differences.
