Conteúdo: |
The inhibitory activity of essential oil from rhizomes of Cyperus giganteus Vahl. was investigated in bioassays on seed germination, radicle and hypocotyl elongation of 3 common weed species [Mimosa pudica Mill., Senna obtusifolia (L.) Irwin & Barneby and Pueraria phaseoloides (Roxb.) Benth] of Amazon region. The major constituent of essential oil 'cyperotundone' was also tested. The inhibitory effects of essential oil and cyperotundone were found concentration dependent, except on seed germination of M. pudica and P. phaseoloides. The S. obtusifolia germination was most adversely affected by the essential oil (15.0% to 20.0%). The essential oil proved more potent than cyperotundone on the radicle and hypocotyl growth. The essential oil reduced the hypocotyl and radicle growth of M. pudica by 32 and 55%, respectively. Cyperotundone was more inhibitory to the radicle (34.0%) than hypocotyl (20.0%) growth of P. phaseoloides. Cyperotundone can be considered an allelochemical and essential oil i.e. as an allelopathic agent. |
