Allelopathic Interactions between Seeds of Portulaca oleracea L. and Crop Species

Allelopathy is described as the interference to plant growth resulting from chemical interactions among plants and other organisms mediated through release of bioactive secondary metabolites. Since only a few studies have been reported about role seed allelopathy, an experiment was designed evaluate seeds Portulaca oleracea L. crop species common bean (Phaseolus vulgaris L.), onion (Allium cepa sugar beet (Beta broad (Vicia faba pea (Pisum sativum L.) on seedling parameters. The results indicated that P. had negative effect germination A. cepa. Conversely, in presence vulgaris, cepa, B. strongly reduced with higher inhibitory found for highest root shoot length observed vulgaris. Seedling vigor all decreased oleracea. Our suggest exhibited high allelopathic effects against can be used potential bio-herbicides future screening programs.
