| Nota de conteúdo | <br/><br/>ABSTRACT<br/>Background: Plants synthesize compounds of specialized metabolism<br/>to defend themselves against biotic and abiotic stresses. These<br/>compounds could be used as models for pesticide development. Among<br/>the species that have not yet been studied for the potential to produce<br/>active compounds is the kidney leaf mud plantain (Heteranthera<br/>reniformis).<br/>Objective: The goal was to evaluate the effect of hexanic, ethyl acetate<br/>and methanolic extracts of H. reniformis leaves on cress (Lepidium<br/>sativum) seed germination to determine which one have the highest<br/>biological activity; and to evaluate different concentrations of extract with<br/>the highest biological activity on lettuce (Lactuca sativa), barnyard grass<br/>(Echinochloa sp.) and giant arrowhead (Sagittaria montevidensis)<br/>germination.<br/>Methods: The seeds were placed on petri dishes containing two sheets<br/>of germitest paper, and after the application of the extract, they were<br/>sealed and placed in growth chambers with controlled temperature and<br/>photoperiod. The variables analyzed were 1st and 2nd germination count,<br/>germination speed index and length of the aerial part and roots.<br/>Results: The ethyl acetate extract provided greater phytotoxicity on cress<br/>than the other extracts. In general, the highest concentration of ethyl<br/>acetate extract was the most efficient in reducing variables for all species.<br/>Conclusions: The ethyl acetate extract of H. reniformis presents<br/>inhibitory activity on the seeds of cress, lettuce, giant arrowhead and<br/>barnyard grass, but this activity was dependent on the concentration of<br/>the extract and the species studied. H. reniformis synthesizes<br/>compounds with phytotoxic activity and purification of extracts is required<br/>to isolate, identify and characterize the action mechanism of the<br/>compounds with herbicide activity, so that in the future these can be used<br/>as models for the development of herbicides. <br/><br/>Keywords:<br/>Heteranthera reniformis<br/>extracts<br/>weeds<br/>suppression |
