NASCIMENTO, Walnice Maria Oliveira Do; CICERO, Silvio Moure  and  NOVEMBRE, Ana Dionísia da Luz Coelho. Conservation of Euterpe oleracea seeds. Rev. bras. sementes [online]. 2010, vol.32, n.1, pp. 24-33. ISSN 0101-3122.  http://dx.doi.org/10.1590/S0101-31222010000100003.

The açaí palm (Euterpe oleracea Mart.), grown principally for its palm heart and highly nutritious berrys, has recalcitrant seeds which cannot be stored for long periods because they do not resist drying or low temperatures. The effects of seed moisture content and storage temperature on the maintenance of seed quality were investigated using açaí palm cultivar BRS Pará seeds conditioned in polyethylene bags at moisture contents of 43.4%, 37.4%, 30.3%, 26.1%, 21.0%, 15.1% and 11.9% and storage temperatures of 20 ºC, 15 ºC and 10 ºC for 360 days, periodic samples being taken to determine moisture content, germination and vigor. At all the temperatures studied, partial drying to a water content of 37.4% did not produce any immediate effects on germination or vigor but as the water content dropped there was progressive deterioration until at 15.1% germination ceased. After 360 days, seeds with a water content of 21.0% or less did not germinate independent of storage temperature. Seeds with a water content of 43.4% stored at 20 ºC remained viable for up to 270 days.

Keywords : açaí palm; drying; deterioration; vigor; water content.
