Dependence of the rutin content in buckwheat plants on the sowing method, variety and seeding rate

The quantitative content of flavonoids was determined in terms of rutin in buckwheat plants selected during the mass flowering phase in an experiment to study some techniques of technology: seeding rates (1.2 and 2.5 million germinating grains per 1 ha); seeding methods (ordinary with the row width of 15 cm and cross-row with the row width of 30 cm); varieties ("Zemlyachka", "Zhdanka"). The amount of rutin in buckwheat plants according to the experiment variants was in the range of 2.3 - 5.1 %.A more significant contribution to the content of flavonoids in terms of rutin belonged to the seeding rate - 60.6%, the share of the variety influence was only 4.6%. On average significant differences in the amount of rutin were not shown by the methods of sowing for the studied varieties.
