Fagopyrum esculentum is well known as a weed suppressing crop due to its strong competitive and allelopathic characteristics. The possible allelopathic compounds in buckwheat include compounds such as flavonoids, fatty acids, phenolic acids, etc. Less attention has been paid to other phenolic compounds, specifically eugenol, o-eugenol, coniferyl alcohol and 3,4,5-trimethoxyphenol as possible allelochemicals. The effects of these compounds on germination and plant growth were tested on seven plant species. The results of our study showed that eugenols, coniferyl alcohol, or 3,4,5-trimethoxyphenol are minority components of the buckwheat plant. Eugenol reached the highest concentration (1.16 mu g/g DW in buckwheat leaves) from these compounds and they probably do not have a significant function in the allelopathy of common buckwheat. However, due to the inhibitory effects on germination and plant growth, eugenol could be utilized in the plant protection of sustainable agriculture.
