The present study investigated integrated effects of two allelopathic plant water extracts (WE) ( [AMBEL] and [XANST]) and a herbicide (mesotrione) on morphological (height and fresh weight of plants) and physiological (pigments content) parameters of and . Also, the study aimed to identify the main components of AMBEL and XANST WE and to evaluate their potential allelopathic effects. Of the 18 investigated compounds, 13 were detected in both tested WE, and -coumaric acid was the leading component in AMBEL, while quinic acid was the predominant component of XANST. The WE of both weed species and their mixtures with the herbicide exhibited more powerful allelopathic effects on fresh weight and content of pigments than on the height of and . The results showed that all measured parameters of both weeds were inhibited in treatments with mesotrione and its mix with AMBEL and XANST WE. The data revealed a highly significant difference in effects ( < 0.05) between control weeds and those treated with AMBEL WE and mesotrione, where the inhibition of fresh weight was over 90%, while the inhibition of pigments content exceeded 80%, and plant height was inhibited by over 70%.
本研究调查了两种化感植物水提物（[AMBEL]和[XANST]）和一种除草剂（麦草畏）对和的形态（植株高度和鲜重）和生理（色素含量）参数的综合影响。此外，本研究旨在确定 AMBEL 和 XANST 水提物的主要成分，并评估它们的潜在化感作用。在所研究的 18 种化合物中，有 13 种在两种测试水提物中均被检测到，阿魏酸是 AMBEL 的主要成分，而奎尼酸是 XANST 的主要成分。两种杂草的水提物及其与除草剂的混合物对鲜重和色素含量的化感作用强于对和高度的化感作用。结果表明，在麦草畏及其与 AMBEL 和 XANST 水提物混合物的处理中，两种杂草的所有测量参数均受到抑制。数据显示，受 AMBEL 水提物和麦草畏处理的杂草与对照杂草之间的效果存在显著差异（ < 0.05），其中鲜重抑制率超过 90%，色素含量抑制率超过 80%，株高抑制率超过 70%。
