Abstract The novel-weapons and homeland-security hypotheses are based on the idea that aliens natives not adapted to each other’s allelochemicals as they did co-evolve. However, only a few studies have tested this, it remains unclear how important co-evolutionary history is in determining strength of allelopathic interactions between natives. Here, we for potential pairwise effects other five a...

Allelopathy offers potential for weed control through the production and release of allelochemicals from leaves, flowers, seeds, stems and roots.  In this research, allelopathy potentials of ethanolic and aqueous extracts of Vinca rosea L. leaves were evaluated. Three extract concentrations, including 2.5, 5 and 10% (w/v) of both aqueous and ethanolic were prepared from a 10% w/v stock solution...
