Abstract

KANIESKI, Maria Raquel; CHASSOT, Tatiane  and  MUNIZ, Marlove Fátima Brião. Effects of the Nerium Oleander L. aqueous extract in the germination and sanity of the Peltophorum dubium (Sprengel) Taubert seeds. Rev. de Ciências Agrárias [online]. 2008, vol.31, n.2, pp.119-126. ISSN 0871-018X.

The use of plant extracts in the fungi control can be an alternative to the use of chemicals. This work has the purpose to test the efficiency of the aqueous extract obtained from leaves of Nerium oleander (espirradeira) on seed germination of Peltophorum dubium (canafístula), as well on seedling vigour and seed sanity. Nine treatments were tested, with three concentrations of extract: 0, 50 and 100%, and three assay times: 15, 30 and 45 minutes. It was found that the aqueous extract of N. oleander was not effective for controlling the pathogens associated with P. dubium seeds, and there is an increase of fungi incidence. However, the aqueous extract of N. oleander helped seed germination and vigour of the resulting seedlings and the most infected seeds were the ones showing better germination and development.

Keywords : Peltophorum dubium; Nerium oleander; plant extracts and pathogens.
