Efeito do extrato de Cyperus rotundus na rizogênese

the cyperus rotundus is an herbaceous perennial plant that multiplies sexually from seed and asexually from bulbs, tubers and underground rhizomes. thus, the present work aimed to assay the effect of c. rotundus extract on the rhizogenesis of solanum lycopersicum leaves. the studies were performed in the laboratory of chemistry and greenhouse, at in cca/alegre/es. the extract was prepared from 2g of c. rotundus and 40ml of solvent (methanol pa, ethanol pa and distilled water). the experimental design utilized to test the extract’s effect on rhizogenesis was entirely random, containing 17 treatments, 6 replicates and 6 plants per replicate. the effective treatments were obtained with aqueous extracts at 100, 50 and 25%. however, the best result was observed for the aqueous extract of 50%, similar to the positive control aib. the results obtained with the use of cyperus rotundus’ extract, seem to be promising, although further studies are needed to demonstrate the usefulness of cyperus rotundus’ extract on rhizogenesis.
