This study was conducted to determine if common buckwheat (Fagopyrum esculentum Moench) residues affect a phenolics composition in soil, and are effective for limiting emergence, growth and metabolic changes in barnyard grass (Echinochloa crus-galli (L.) P. Beauv.), wild oat (Avena fatua L.), yellow foxtail (Setaria pumila Schult.), silky windgrass (Apera spica-venti L.), catchweed bedstraw (Galium aparine L.), scentless mayweed (Matricaria inodora L.), and tiny vetch (Vicia hirsuta L.). In the study, the residues of 14-day-old buckwheat plants were used (cv. Hruszowska). After removal of the above-ground parts, the buckwheat root residues (BRR) remained in the soil for an additional 7 days before the weeds were sown. For comparison, under the same cultivation conditions, the effect of entire buckwheat plant residues (BPR) in soil was assessed. BPR and BRR in the soil caused a decrease in the emergence of all weed species except the tiny vetch. The growth of barnyard grass, wild oat, yellow foxtail, catchweed bedstraw, and scentless mayweed was inhibited by BRR, but not BPR. BRR had a particularly strong inhibitory effect on the growth of scentless mayweed (SM) and catchweed bedstraw (CB). Thirty-day-old SM and CB control plants were about 4 and 3.5 times higher, respectively, than plants growing in the presence of BRR. Furthermore, chlorophyll and carotenoid contents in the barnyard grass and catchweed bedstraw were more prominently reduced by BRR than BPR. Stressful conditions caused by buckwheat residues in the soil increased the level of phenolic compounds in the tissues of weeds examined. Soil with buckwheat residues contained a low level of phenolic compounds, which may indicate their slow release from the residue or rapid utilisation by microorganisms. These phenolic compounds probably cannot be directly responsible for allelopathic inhibition of weed emergence and growth.

进行这项研究是为了确定常见的荞麦（Fagopyrum esculentum Moench）残留物是否影响土壤中的酚类成分，并有效地限制bar草的出现，生长和代谢变化（Echinochloa crus-galli（L.）P. Beauv。） ，野生燕麦（Avena fatua L.），黄色狐尾（Setaria pumila Schult。），丝滑草（Apera spica-venti L.），杂草草（Galium aparine L.），无臭的五花草（Matricaria inodora L.）和小etch子（野豌豆L.）。在这项研究中，使用了14天大的荞麦植物的残留物（Hruszowska公司）。除去地上部分后，在播种杂草之前，荞麦根残留物（BRR）在土壤中再保留7天。为了进行比较，在相同的栽培条件下，评估了整个荞麦植物残留物（BPR）在土壤中的作用。土壤中的BPR和BRR导致了除微小紫etch之外所有杂草物种的出现减少。RR草抑制了of草，野燕麦，黄狐尾，杂草稻草和无臭的甲草的生长，但B草抑制了BPR。BRR对无臭美藻（SM）和杂草稻草（CB）的生长具有特别强的抑制作用。30天的SM和CB对照植物分别比在存在BRR的情况下生长的植物高约4倍和3.5倍。此外，与BPR相比，BRR显着降低了grass草和杂草稻草中叶绿素和类胡萝卜素的含量。土壤中荞麦残留物造成的压力条件增加了所检查杂草组织中酚类化合物的水平。荞麦残留物的土壤中酚类化合物含量低，这可能表明它们从残留物中释放缓慢或被微生物快速利用。这些酚类化合物可能不能直接导致化感抑制杂草的出现和生长。荞麦残留物的土壤中酚类化合物含量低，这可能表明它们从残留物中释放缓慢或被微生物快速利用。这些酚类化合物可能不能直接导致化感抑制杂草的出现和生长。荞麦残留物的土壤中酚类化合物含量低，这可能表明它们从残留物中释放缓慢或被微生物快速利用。这些酚类化合物可能不能直接导致化感抑制杂草的出现和生长。
