Moisture content is expressed on a fresh weight basis. Values represent mean (n = 3) with SE shown in parentheses. There were no significant differences in seed moisture content between storage treatments. Silica eRH was measured using a hygrometer. A single measurement was performed per treatment using silica gel sachets from two of the three replicates
