- Abstract
- Buckwheat is a pseudocereal with high nutritional and nutraceutical properties. Although common buckwheat (Fagopyrum esculentum) is the main cultivated species, Tartary buckwheat (Fagopyrum tataricum) is attracting more and more interest. The two buckwheat species differ in their reproduction: F. esculentum is self-incompatible, heterostylous and entomophilous and produces white to pink flowers while F. tataricum is self-compatible and produces small greenish homostylous flowers. Thus, insects are necessary for pollination and reproduction of F. esculentum, but their contribution to the reproduction of F. tataricum has not been studied so far. To improve our understanding of the reproduction of both species, we compared plant growth, yield parameters and pollination of two varieties of F. esculentum ('La Harpe' and 'Darja') and F. tataricum ('Islek' and 'Zlata') under field conditions in Belgium. Fagopyrum esculentum flowered earlier, produced fewer nodes, fewer branches, fewer inflorescences, but more flowers per inflorescence than F. tataricum. Yield was higher in F. tataricum, while thousand kernel weight was higher in F. esculentum. Yield ranged from 2037 kg/ha to 3667 kg/ha depending on species and year. With respect to pollination, F. esculentum attracted a greater diversity of insects than F. tataricum, which generally attracted smaller insects. Syrphidae were the primary visitors to both buckwheat species. In addition, Syrphidae were the most common insects in terms of density and foraging time on F. tataricum. No differences in pollinators or visiting behavior were observed between varieties for any species. Fagopyrum esculentum produced nectar to attract pollinators, but nectar could not be extracted from F. tataricum under field conditions. Our results showed that both species grow well under Belgian conditions and that both species are visited by insects, suggesting that they may also contribute to the reproduction of F. tataricum as observed for F. esculentum.
