The buckwheat is a plant species with a high ability to produce secondary metabolites such as flavonoids. Together with rutin, the dominant flavonoid of the Fagopyrum Mill genus representatives (The Common buckwheat (F. esculentum Moench), the Tartary buckwheat (F. tataricum (L.) Gaertn.) and the Perennial buckwheat (F. cymosum Meissn.)), quercetin, vitexin, quercitrin, orientin, anthocyanides, phenolcarbonic acids and other compounds were found in buckwheat plants. Due to their considerable reactivity, flavonoids participate in the processes of photosynthesis, respiration, growth, reproduction and defence against different stresses. The purpose of this article is to overview the processes of flavonoid biosynthesis and accumulation during the growth and development stages of buckwheat plants under the influence of external factors regarding its species diversity. Flavonoids content and induction were examined in vitro culture.

荞麦植物中类黄酮生物合成和积累的某些方面

荞麦是具有高能力产生次生代谢产物（如黄酮类）的植物。芦丁与荞麦属（Fagopyrum Mill）属代表的优势类黄酮（普通荞麦（F. esculentum Moench），the荞麦（F. tataricum（L.）Gaertn。）和多年生荞麦（F. cymosum）在荞麦植物中发现了槲皮素，葡萄黄素，槲皮素，Orientin，花青素，酚碳酸和其他化合物。由于黄酮类化合物具有很高的反应性，它们参与了光合作用，呼吸作用，生长，繁殖和防御不同压力的过程。本文的目的是概述荞麦植物在其物种多样性的外部因素影响下的生长和发育阶段的黄酮生物合成和积累过程。在体外培养中检查了类黄酮的含量和诱导。
