Changes in viability with storage time at room temperature and humidity for two seed morphs of Suaeda splendens, subsequently germinated in a range of NaCl treatments for 303 d. (A) Black seeds; (B) brown seeds. Values represent means ± s.e., n = 4 (25 seeds per replicate). Different letters indicate means for any NaCl treatment that are significantly different with time (Tukey test; P < 0·05); * all means at the same time have the same letter. For black seeds only were there significant differences for 900 mol m−3. Viable was defined as all seeds that had germinated at 5/15 °C plus ungerminated ones with a live embryo.
