‘G0’ indicates the fraction germination prior to storage, ‘G1_obs’ the fraction germination examined for wheat in 2011 and for barley in 2012 and ‘G1_exp’ the expected fraction germination based on the equilibrium relative humidity. ‘Yr_obs’ and ‘Yr_exp’ denote the observed and expected number of years for germination to drop from G0 to G1_obs.

^aOnly samples with complete vacuum are presented.
