ABSTRACT:      The  objective  of  this  work  was  to  evaluate  the  longevity  of  Astronium  fraxinifolium  Schott  seeds  collected  in  the  states of Goiás and Minas Gerais in Brazil and analyse its association with local weather conditions during the vegetative and reproductive phases (temperature, precipitation and altitude) and seed oil content. Longevity was tested in a controlled ageing test at a constant temperature of 45 °C and relative humidity (RH) of 60, 65 or 70%, followed by germination. Seed longevity was inferior in seeds collected in the state of Minas Gerais and superior in seeds collected in the state of Goiás. There was a significant positive correlation between seed longevity and temperature and a significant negative correlation between seed longevity and altitude. No correlation was found between rainfall and seed longevity. In addition, we found a significant negative correlation between seed longevity and oil content, which was associated with an increase in malondialdehyde (MDA) content. Thus, the influence of the maternal environment during seed production should be considered during seed collection for improved ex situ conservation of A. fraxinifolium seeds.

RESUMO:     O  objetivo  deste  trabalho  foi  avaliar  a  longevidade  de  sementes  de  Astronium  fraxinifolium  Schott  coletadas  nos  estados  de  Goiás  e  Minas  Gerais,  no  Brasil,  e  analisar  a  associação  com  as  condições  climáticas  locais  (temperatura,  precipitação e altitude) e teor de óleo da semente. A longevidade foi testada através de um teste de envelhecimento controlado a uma temperatura constante de 45 °C e umidade relativa (UR) de 60, 65 e 70%, seguido de germinação. A longevidade das sementes foi inferior nas sementes coletadas no Estado de Minas Gerais e superior nas sementes coletadas no Estado de Goiás. Houve correlação significativa e positiva da longevidade das sementes com a temperatura e correlação significativa e  negativa  com  a  altitude.  Não  foi  encontrada  correlação  entre  a  precipitação  e  a  longevidade  das  sementes.  Além  disso,  encontramos uma correlação significativa e negativa da longevidade das sementes e do teor de óleo, que foi associada a um aumento no conteúdo de malonaldeído (MDA). Assim, a influência do ambiente materno durante a produção de sementes pode ser considerada durante a coleta de sementes para melhor conservação ex situ de sementes de A. fraxinifolium.
