CATUNDA, Paulo Henrique Aragão; VIEIRA, Henrique Duarte; SILVA, Roberto Ferreira da  e  POSSE, Sheila Cristina Prucolli. Influence of moisture content, packaging and storage environment on yellow passion fruit seed quality. Rev. bras. sementes [online]. 2003, vol.25, n.1, pp.65-71. ISSN 0101-3122.  http://dx.doi.org/10.1590/S0101-31222003000100011.

This experiment was designed to verify the influence on yellow passion fruit seed quality of 8 and 10% moisture content (wet basis), package type ( flexible aluminum pouch and paper bag) and the storage environment: laboratory room, temperature varying between 21-29ºC and relative humidity between 50-80%, and two controlled conditions, 18ºC/24%RH and 4ºC/60%RH. The seeds placed in the different packaging were stored in the three different environments for bimonthly evaluation. The following determinations were carried out: seed moisture content, germination and the vigor determined by the accelerated aging test. The tests indicated that seeds conditioned with 10% moisture content presented a drastic reduction in germination, when placed in impermeable packaging in laboratory room conditions, while the treatment with temperature of 4ºC and 60% RH showed the best results to preserve the seed viability, regardless of the type of packaging.

Palavras-chave : seed; passion fruit; germination; vigor; storage.
