Allelopathic effect of five invasive plants on seed germination and growth of wild mustard

Presently, chemical control is the most used method for plant protection. However, it not an approach that environmentally sustainable. Alternative IPM methods include biological such as Allelopathy can be a good alternative in protection.Allelopathy defined direct or indirect interaction, whereby allelochemicals released by one organism influence physiological processes of other neighboring organisms.Laboratory experiments were conducted to investigate allelopathic effect five weeds, Eriochloa villosa (ERIVI), Panicum miliaceum (PANMI), Cannabis sativa (CANSA), Sorghum halepense (SORHA), Asclepias syriaca (ASCSY) on germination and growth wild mustard (Sinapis arvensis L.). These weeds are dangerous during field cultivation their weed difficult.The extracts from leaves stem examine potential inhibition germination, root length, shoot length full growth.The phenomenon allelopathy was detected examined plants. In case plants, also increased with increasing concentration. The results show Johnson grass had significant seed germination.
