Investigating the Allelopathic and Bioherbicidal Potential of <i>Solidago altissima</i> with a Focus on Chemical Signaling in <i>Trifolium repens</i>
Invasive weed species exhibit both advantages, such as the potential for allelochemicals in bioherbicide development, and risks, including their threat to crop production. Therefore, this study aims to identify an allelochemical from <i>Solidago altissima</i>, an invasive weed species. T...

| description | Invasive weed species exhibit both advantages, such as the potential for allelochemicals in bioherbicide development, and risks, including their threat to crop production. Therefore, this study aims to identify an allelochemical from <i>Solidago altissima</i>, an invasive weed species. The dose-dependent effects of <i>S. altissima</i> shoot and root extracts (SSE, SRE) on the signaling in the forage crop <i>Trifolium repens</i> and germination in various weed species (<i>Echinochloa oryzicola</i>, <i>Cyperus microiria</i>, <i>Alopecurus aequalis</i>, <i>Portulaca oleracea</i>, and <i>Amaranthus retroflexus</i>) were evaluated. The results showed that the <i>T. repens</i> seedlings treated with root extracts exhibited a significant decrease in plant height, dry weight, and chlorophyll content, along with an increase in H<sub>2</sub>O<sub>2</sub> levels. Additionally, antioxidant activities, such as superoxide dismutase, catalase, and peroxidase enzyme activities, were significantly elevated in <i>T. repens</i> treated with SRE. Moreover, SRE treatment significantly inhibited the seed germination of all tested weed species in a concentration-dependent manner. Gas chromatography-mass spectrometry analysis of <i>S. altissima</i> root extract identified a high concentration of methyl kolavenate, a clerodane diterpene predicted to act as a phytotoxic agent. These findings highlight the potential of <i>S. altissima</i> for the development of crop-protective agents while emphasizing its potential risks in agriculture. |
