Understanding how allelochemicals with herbicidal activity are released in plant interactions is key to developing sustainable weed control strategies. This study aimed to investigate the herbicidal activity and metabolic profile of Jacq. leachates. bioassays were performed with . leaf leachates to evaluate their effects on the germination and early growth of L. and (L.) Fedde. (DIGIN.). The leachate extracts were subsequently characterized via liquid chromatography high-resolution mass spectrometry-based metabolomics and molecular networking. The results showed that weed germination and seedling development were significantly affected by the . leachates. Metabolomic analysis revealed that allelochemicals belonging to the classes of alkaloids, fatty acids, phenolic compounds, steroids, and terpenoids are potentially involved in herbicidal activity. These findings suggest that . could be explored as a natural alternative for sustainable weed management, potentially reducing the dependence on synthetic herbicides.
了解具有除草活性的化感物质在植物相互作用中如何释放是制定可持续杂草控制策略的关键。本研究旨在调查Jacq.浸出液的除草活性和代谢谱。用.叶浸出液进行生物测定,以评估其对L.和(L.) Fedde. (DIGIN.)发芽和早期生长的影响。随后通过基于液相色谱高分辨率质谱的代谢组学和分子网络对浸出液提取物进行表征。结果表明,杂草发芽和幼苗发育受到.浸出液的显著影响。代谢组学分析表明,属于生物碱、脂肪酸、酚类化合物、类固醇和萜类的化感物质可能参与除草活性。这些发现表明,.可作为可持续杂草管理的天然替代品进行探索,有可能减少对合成除草剂的依赖。
