Some introduced invasive species may be competitively superior to natives because they release allelochemicals, which egatively affect native species. Allelochemicals can be immediately effective after being released but can also persist in soils, esulting in a legacy effect. However, to our knowledge there are no studies which distinguish between allelopathic legacy and mmediate allelopathy of...

The allelopathic potential of methanol extract from Sargassum virgatum (Mert.) AG. (Phaeophyta) on the seeds germination and seedlings growth of Lettuce (lactuca sativa), Tomato (Lycopersicon esculentum), and barley (Hordeum vulgare) was conducted. Methanol extracts from S. virgatum at concentrations 25, 50, 100, and 200 ppm were applied under laboratory conditions. Tomato, lettuce and barley g...

Weeds are plant disturbing organism that affect yields through competition and allelopathy. However, not much is known about weed diversity in swamps, so research needed to identify their types compounds as a control strategy. This study was conducted using survey method from January March 2020 at the Barito Kuala District, South Kalimantan. Thirty villages were randomly selected each of eight ...

Plant-plant interference is the combined effect of allelopathy, resource competition, and many other factors. Separating allelopathy from resource competition is almost impossible in natural systems but it is important to evaluate the relative contribution of each of the two mechanisms on plant interference. Research on allelopathy in natural and cultivated plant communities has been hindered i...

1. Allelopathic interactions between invasive and native species have been suggested to be an important mechanism for the success of some of the most aggressive plant invaders. However, field experiments that test the effects of natural levels of allelopathic compounds on coexisting native species are exceptionally rare. 2. In this study, we analyzed the allelopathic effects of the invasive tre...
