The purpose of this study was to investigate the effects of endophytic fungi from tartary buckwheat on the host sprout growth and functional metabolite production. Without obvious changes in the appearance of the sprouts, the exogenous fungal mycelia elicitors notably stimulated the sprout growth and rutin accumulation, and the stimulation effect was mainly depended on the mycelia elicitor species along with its treatment dose. Three endophytic fungi Fat6 (Bionectria pityrodes), Fat9 (Fusarium oxysporum) and Fat15 (Alternaria sp.) were screened to be the most effective candidates for promoting F. tataricum sprout growth and rutin production. With application of polysaccharide (PS, 150 mg/l) of endophyte Fat6, PS (200 mg/l) of endophyte Fat9, and PS (150 mg/l) of endophyte Fat15, the rutin yield was effectively increased to 47.89 mg/(100 sprouts), 45.85 mg/(100 sprouts) and 46.83 mg/(100 sprouts), respectively. That was about 1.5- to 1.6-fold compared to the control culture of 29.37 mg/(100 sprouts). Furthermore, the present study revealed that the biosynthesis of the functional flavonoid resulted from the stimulation of the phenylpropanoid pathway by mycelia polysaccharide treatments. Application of specific fungal elicitors could be an efficient strategy for improving the nutritional and functional quality of tartary buckwheat sprouts.

The use of buckwheat as a source of rutin for medicine or food supplement requires a high content of this component in pimary row materials. The study was aimed at the investigation of the influence of stand density and sowing dates on the rutin content in the aboveground parts at the stage of flowering and achenes of two buckwheat species (Fagopyrum esculentum and Fagopyrum tataricum). The rutin content in the aboveground parts of buckwheat was significantly higher in plants sown in mid-May. The sowing date did not influence the rutin content in the achenes. The whole buckwheat plant contained the highest content of rutin in 25 cm rows with a sowing ratio of 200 achenes per square metre. However, the final rutin amount obtained from a buckwheat stand depended on the production of biomass. Common buckwheat provided a higher rutin yield because it produced a higher amount of biomass of inflorescences, the part rich in this flavonoid. Therefore 12.5 cm rows with 400 seeds per square metre are suitable for rutin production because of the higher number of plants. We can recommend tartary buckwheat for achene production as a source of rutin for human nutrition or food supplement because it provides twenty-fivefold more rutin than common buckwheat.
