Phenotypic differences between SD7-1^D and SD7-1^d. (A) Abscisic acid (ABA) accumulation in developing seeds. Bars represent SD of three replicates. (B) Seed moisture and weight. Seeds in amounts of 100 were sampled from a plant; bars represent SD of 10 plants. (C) Germination of intact seeds (control), hull-removed seeds, and seeds treated with gibberellic acid (GA₃) and heated at 45° for 7 d. Germination was evaluated with three samples (50 seeds/sample) from a plant; bars represent SD of 15 plants. (D) Germination of pericarp/testa-removed caryopses at two different temperatures. Germination was evaluated with 100 caryopses.
