Germination behavior of DOG1 under different environmental circumstances and in different genetic backgrounds. (A) GA requirement for germination. Germination on various concentrations of GA4+7 of after-ripened seeds of GA1-3 dog1, GA1-3 DOG1-Ler, and GA1-3 DOG1-Cvi and on the GA-deficient seeds ga1-3 dog1, ga1-3 DOG1-Ler, and ga1-3 DOG1-Cvi. Seeds of GA1-3 dog1 and ga1-3 dog1 were 1 month after-ripened, and seeds of the other combinations were after-ripened for 25 months. Percentages are averages of four measurements ± SE. (B) Germination in darkness. Shown are germination percentages of after-ripened seeds of dog1, Ler, and NILDOG17-1 under different environmental conditions, in light, in light after a cold stratification, in darkness, and in darkness after a cold stratification. The means and SE of triplicates are shown. (C) ABA sensitivity of the three DOG1 alleles. Shown is germination in different ABA concentrations of after-ripened seeds of dog1, DOG1-Ler, and DOG1-Cvi. Seeds of dog1 and DOG1-Ler were after-ripened for 4 months, and seeds of DOG1-Cvi were after-ripened for 25 months. The percentages are means of triplicates ± SE. (D) ABA dependency of DOG1. Shown is germination behavior of aba1-1 in two different DOG1 backgrounds (DOG1-Ler and DOG1-Cvi) at different time points after seed harvest.
