description | This study explores how hydroalcoholic extracts of <i>Campomanesia lineatifolia</i> R. and P. seeds affect the germination and viability of seeds from two weeds, <i>Rumex crispus</i> and <i>Amaranthus hybridus</i>. The phenolic compounds were initially characterized using ultra-high-performance liquid chromatography. In seeds sown in Petri dishes, four concentrations of hydroalcoholic extracts (0%, 3%, 6%, and 9% <i>w</i>/<i>v</i>) were used for single and continuous applications. The mean germination speed, mean germination time, germination percentage, and seed viability were evaluated. Epigallocatechin gallate, quercetin-3-glucoside, epicatechin gallate, ursolic acid, epigallocatechin, and trans-cinnamic acid were the main compounds discovered in that order. Notably, while the germination percentages of both species were reduced with a single application (38.5% for <i>R. crispus</i> and 52% for <i>A. hybridus</i>), they were reduced by 76.2% and 58.34% with a continuous application, respectively. A delay in germination was also observed, which produced changes in germination speed throughout the experiment. With a 9% application, the number of nonviable seeds of <i>R. crispus</i> increased by 40.53%, whereas in <i>A. hybridus</i>, viability decreased by at least 70.8%. Overall, the phenolic compounds in <i>C. lineatifolia</i> extract are thought to inhibit the germination process of the evaluated species. |
