摘要

This research investigates the impact of water-based extracts on allelopathic interactions involving the invasive weed Xanthium strumarium L. on the germination, seedling development and the biomass of Glycine max L. (Soyabean), Pisum sativum L. (Pea), and Oryza sativa L. (Rice). The study involved preparing extracts from both the aerial and underground parts of the weed at varying concentrations, viz., 1 mg/mL, 25 mg/mL, and 75 mg/mL. The experimental design included soaking seeds in these extracts and measuring subsequent germination rates, seedling lengths, and biomass accumulation over 27 days. The results showed that extracts from both the aerial and underground parts of the weed significantly inhibited germination and growth. Specifically, increasing extract concentrations led to decreased mean shoot and root lengths across all tested crops. The aerial extracts generally showed greater inhibitory effects than the underground extracts. These findings underscore the significant allelopathic potential of the invasive weed, that adversely affects plant progression and crop yield. The study highlights the critical need for targeted strategies for weed management to mitigate the impact of invasive species on agricultural systems, and to enhance crop productivity.
