Abstract

Allelopathy is the interference caused by chemical substances produced by plants in community organisms, causing both beneficial and harmful effects. Since the genus Solanum has great allelopathic potential, the objective of the present study was to evaluate the allelopathic effect of hexanic, methanolic and ethyl acetate leaves extract from Solanum pimpinellifolium on the germination of Lactuca sativa and Bidens pilosa. The extracts were obtained by maceration at room temperature for 7 days. Then they were dried and diluted to concentrations 1, 2 and 5mg / ml. Then, 100 seeds of each species were distributed in Petri dishes moistened with different concentrations of each extract and placed to germinate under constant light in a BOD type germination chamber. The bioassays were monitored daily, obtaining at the end of 7 days thepercentage of germination and germination speed index (GSI). Of the three extracts, ethyl acetate performed better, decreasing the speed and percentage of germination in all concentrations, with the concentration 5mg/mL showing only 7% germination for L. sativa. For B. pilosa the hexanic extract presented better performance, decreasing the speed and the germination percentage in all concentrations. Phytochemical analyzes performed using thin layer chromatography techniques on leaf extracts of Solanum   pimpinellifolium identified four chemical groups: flavonoids, saponins, alkaloids and mono and diterpenes, the latter being present in all analyzed extracts
