En un estudio sobre la germinacion en el banco de semillas de cedrela fissilis Vellozo (Meliaceae) en monte nativo se observo la demora en el incio y disminucion de la germinacion en el caso de una parcela. A los fines de determinar las posibles causas de la demora, se realizaron comparaciones entre las parcelas cuyas semillas presentaron valores normales de la germinacion y los valores de la germinacion en la parcela con demora. Se realizaron estudos de las condiciones micrometeorologicas de las pracelas, determinaciones quimicas de los primeros 5 cm de suelo y siembra bajo condiciones ambientales controladas en laboratorio usando los diferentes sustratos del bosque. Al comparar los promedios de las variable micrometeorologicas y las propiedades qumicas del lsuelo se observo en la parcela con germinacion demorada mayor temperatura y menor humedad relativa, con diferencias no significativas, mayor pH y mayores concentraciones de Ca, Mg y K en relacion con las parcelas con germinacion normal. |

The aim of this study was to evaluate the antiprotozoal activity of essential oils from Varronia curassavica accessions against different stages of Ichthyophthirius multifiliis . Essential oils from each accession were tested in vitro at the concentrations 0, 10, 25, 50, 75, 100, and 200 mg/L. The VCUR-001, VCUR-202, VCUR-509, and VCUR-601 accessions presented the major compounds αpinene, germacrene D-4-ol, (E)-caryophyllene and epiglobulol, and sabinene, respectively. These isolated compounds were tested in vitro at a concentration proportional to that foundin the essential oil which caused 100% mortality of the parasite. The concentrations of 10 and 50 mg/L of the essential oil of accession VCUR-202 provided 100% mortality of trophonts and tomonts, respectively. For the accession VCUR-509, 100% mortality of trophonts and tomonts was observed at concentrations 75 and 200 mg/L of essential oil, respectively. The same mortality was observed at concentration 200 mg/L in both stages of the parasite for the other accessions. The major compounds αpinene, sabinene, and the (E)-caryophyllene + epiglobulol mixture caused 100% mortality of trophonts and tomonts. The in vivo assay for white spot disease control was performed in therapeutic bath of 1 h with the essential oil of accession VCUR-202 at concentrations of 0.5 and 2.0 mg/L. A significant reduction of about 30% of trophonts on infected fish was observed, independent of the oil concentration. The V. curassavica essential oil, especially the VCUR-202 accession, is a potential source of raw material for the formulation and commercialization of bioproducts to control freshwater white spot disease in fish.
