Descripción:	Nine coffee seeds samples submitted to different post-harvest treatments were tested in terms of ultra-weak delayed luminescence and induced to germinate afterwards. Hyperbolic decay function was used to quantify the time profiles and their fitting parameters were correlated to the correspondent germination vigour (total seedlings' elongation). Good linear relation was found (R2 > 0.85) for the initial value parameter as well as for the decay velocity parameter. These preliminary results point to further tests in order to validate a photonic, non-invasive, non-destructive test for coffee seed's viability analyses.
