“…The suppression effect was found dependent on the extract concentration. Findings of Kenany and El-Darier, (2013), Barkatullah et al, (2010) and those reported by Sultana & Asaduzzama (2012) were also in agreement with our results. It was withal discerned that hot water extracts, especially from leaves, had a more inhibitory effect than methanolic and rain leachates extracts.…”

A laboratory experiment was conducted to evaluate the allelopathic potential of Populus nigra leaves in different guided bioassay on the germination and growth of four different wheat varieties i.e. Ghaznavi, Siran, Atta Habib, and Janbaz. All the extract had differential toxicity against all the four wheat varieties. Hot water extract was observed to be inhibitory than methanolic and rain leachate extract obtained. Furthermore, litter and mulching experiments had also inhibitory effects on the studied parameters. Suppressive effects were linearly correlated with extract concentration. Growthsuppressive effects of the guided-assay were recorded in the order hot water extracts ˃ methanolic extracts ˃ rain leachate extracts. It is suggested that P. nigra leaves possess phytotoxic activities, and further investigations are therefore required against challenging weeds. Filed experiments may be carried out to further expand the perceived allelopathic activities of P. nigra on other crops.

Lantana camara (L.) is considered one of the main invasive plants, and the allelochemicals produced by this species can be defined as bioactive secondary metabolites that mediate chemical interactions between the plant and other organisms and, therefore, play an important role in its succession and establishment. The present study aimed to investigate the effect of L. camara aqueous extracts on the germination and growth behavior of Bidens pilosa (L.) by evaluating physiological parameters (germination rate, germination speed index, seedling performance and structure and membrane integrity), as well as the extract metabolic profile. The extract reduced the germination speed index and seedling growth rate and promoted abnormalities in the geotropism and root development in both populations. The third germination phase was highly affected (more than the phases I and II). Lantadene A and B are the possible compounds conferring the herbicidal properties, and the L. camara extract has a potential to be used in the development of a new environmentally-friendly herbicide.

Lantana camara (L.) is considered one of the main weeds of agricultural crops, and allelochemicals produced by this species may be a source for the development of natural herbicides. In this study, phytotoxic effects of L. camara aqueous extracts on seed germination and seedling growth of Avena sativa (L.) were assessed. The experimental design was completely randomized, in a 2 x 5 factorial scheme, with treatments resulting from two assays, testing five concentrations of the extract (0 %, 2.5 %, 5.0 %, 7.5 % and 10 %; vv-1). During the seed germination, physiological (e.g., seed imbibition, germination and vigor) and biochemical (e.g., catalase, ascorbate peroxidase, proline, phenols, malondialdehyde and hydrogen peroxide) proprieties were evaluated. The leaf extracts of L. camara affected the response variables on A. sativa by reducing the germination speed index (phases I and II) and seed viability (phase III of germination), thus causing a solute leakage and increasing the production of reactive oxygen forms and, finally, lipid peroxidation. Extract concentrations above 2.5 % inhibit the growth of epicotyls. Therefore, the studied allelochemicals showed potential to be exploited in the development of natural herbicides.
