摘要

This study was conducted to determine if common buckwheat (Fagopyrum esculentum Moench) root residues (BRR) in soil are effective in limiting the growth and metabolic responses of barnyard grass (Echinochloa crus-galli (L.) P. Beauv.), wind grass (Apera spica-venti L.), cleavers (Galium aparine L.), and tiny vetch (Vicia hirsuta L.). After removal of above ground parts, BRR of 14-day-old buckwheat plants remained in soil for an additional 7days when the weeds were seeded. After 30days of growth, biomass of above ground parts of the weeds as well as free and bound phenolic acids and flavonoids were determined. Antioxidant capacity and peroxidase activity were measured in barnyard grass and cleavers. The biomass of 30-day-old plants of barnyard grass and cleavers grown in bare soil was approximately 5- and 3.5-fold higher, respectively, than in plants grown in the presence of BRR. BRR did not affect the biomass of wind grass and tiny vetch plants, but activate the antioxidant response, increase in peroxidase activity, and the content of phenolic compounds in weed tissues, which indicates an adaptation to the stressful environmental conditions.

Beauv。），风草（Apera Spica-Venti L.），切割者（Galium Aparine L.）和微小的Vetch（vicia hirsuta l）。去除以上地面部分后，当杂草种植时，14天旧的荞麦植物留在土壤中额外的7天。经过30天的生长后，测定杂草的地下部分的生物量以及游离和结合的酚醛酸和黄酮类化合物。在Barnyard草和切割器中测量抗氧化能力和过氧化物酶活性。在Brr存在下生长的植物，分别在裸露的土壤中长度为3.5倍的稗草和裂解器的30天旧植物的生物量分别大约5-5倍。 BRR没有影响风草和微小的拔蚀植物的生物量，而是激活抗氧化剂反应，过氧化物酶活性增加，杂草组织中的酚类化合物的含量，这表明对压力环境条件的适应。
