The aim of this study was to evaluate the impact of different farming types-organic and conventional-on phenolic content in buckwheat varieties grown in Lithuania. Rutin was identified as the dominant phenolic compound in contrast to both phenolic acids (chlorogenic and neochlorogenic acids) and other flavonoids (quercetin and quercitrin). It was determined that variety had the highest impact (p<0.05) on the phenolic content of various aerial parts of buckwheat. In most cases, farming practice significantly (p<0.05) affected the accumulation of phenolics in buckwheat. Organically grown plants usually contained higher amounts of phenolics than those grown under conventional farming conditions. According to a cluster analysis, varieties Panda, Zaleika, and VB Nojai were found to accumulate the highest amounts of phenolics.
本研究的目的是评估不同种植类型（有机种植和传统种植）对立陶宛种植的荞麦品种中酚类物质含量的影响。与酚酸（绿原酸和新绿原酸）及其他黄酮类化合物（槲皮素和槲皮苷）相比，芦丁被确定为主要的酚类化合物。研究发现，品种对荞麦各个地上部分的酚类物质含量影响最大（p<0.05）。在大多数情况下，种植方式对荞麦中酚类物质的积累有显著影响（p<0.05）。有机种植的植株通常比传统种植条件下生长的植株含有更多的酚类物质。根据聚类分析，发现品种Panda、Zaleika和VB Nojai积累的酚类物质含量最高。
