Time course of B. rapa germination. A, Radicle emergence on media with or without 35 mm Glc and/or 10 μm ABA. Percentages represent assays of 23 to 25 seeds per treatment. B, Changes in fresh weight and developmental events (r.e., radicle emergence; c.e., cotyledon emergence) on media with or without 35 mm Glc and/or 10 μm ABA. C, Effects of Glc and/or ABA on ICL activity in B. rapa seedlings. Data points represent means ± se of duplicate samples, each comprised of three to 10 seeds/seedlings.
