Resumo: | An experiment was carried out at Sâo Manuel Experimental Farm, FCA-UNESP, Botucatu-SP, in 1994 and 1995, aiming to determine the biomass production and essential oil yield of mentrasto (Ageratum conyzoides L. - Asteraceae) in different stages of development. The statistical design used was a complete randomized block with 8 replications and 3 treatments (pre-flowering, flowering and post-flowering). The spacing was 70 cm between rows and 50 cm between plants, with 70 plants/parcel. The seedlings were transplanted 40 days after sowing. After harvesting, the fragments (roots, stems, leaves, flowers) and whole plants were washed, separated and weighted. The extractions of essential oil were done by hydrodistillation, using Clevenger apparatus, for two hours. There were statistic differences (Tukey 5%) in fresh weight of all vegetal parts w'hen harvested in different development stages. About essential oil yield, statistic differences were not verified among the treatments. |
