In order to demonstrate the allelopathic effects of different organs (root, shoot and whole plant) of redroot pigweed (Amaranthus retrofelexus L.) on germination, emergence, growth and development of summer savory (Satureja hortensis L.) under laboratory and greenhouse conditionan experiment was carried out as CRD design with nine and five replications at laboratory and greenhouse of the Faculty of Agriculture, University of Tabriz, Iran, respectively. Results showed the significant effects of different organs aqueous extracts (AEs) of redroot pigweed on germination percentage, germination rate and normal seedlings percentage. Germination rate decreased by shoot, root and whole plant AEs compare with control. Shoot and whole plant AEs of redroot pigweed were able to reduce summer savory biomass more than the root aqueous extract.

This study proposes the evaluation of the phenolic composition of leaves and stems extracts of Rosa canina (Dog rose) and their herbicidal abilities measured using assays of germination rate (G) and germination speed (GI) of lactuca sativa (Lettuce), phalaris truncata and raphanus raphanistrum seeds and assays of its seedling growth. Leaves and stems of dog rose were rich in total phenolics and total flavonoïds with comparative contents. Whereas flavones/flavonols were abundant in leaves extracts and in traces in stems extracts. G and GI of target species seeds and root and shoot length of its plants were reduced from the lowest concentration of both extracts. Reductions of G and GI were more important in presence of leaves dog rose extracts compared to those noted with stems extracts. Raphanus raphanistrum was the most sensitive target species to both extracts. G and GI of this weed were canceled from 30g/l of leaves extract. Root and shoot growth of target species were more inhibited in presence of dog rose leaves extracts. Inhibitions reached 100% from concentrations of 40g/l, 60g/l and 90g/l respectively for wild radish, canary grass and lettuce. The findings allow us to demonstrate that leaves and stems from dog rose could be a prospective residual vegetable source of valuable phytochemicals, for future applications in the field of agroecology and biological weed control.
