Figure 4.

Germination of Mutant dag2 Seeds Is More Dependent on Light and Stratification Than Germination of Wild-Type Seeds, Whereas Germination of Mutant dag1 Seeds Is Less Dependent on These Factors.

(A) Germination rates under standard illumination conditions with seeds pretreated at 4°C. Closed circles, dag2 seeds; closed triangles, Ws seeds; closed squares, dag1 seeds.

(B) Germination in the dark with seeds pretreated at 4°C. The histogram reports germination percentages scored on day 5.

(C) Germination rates under standard illumination conditions with seeds not pretreated at 4°C. Closed circles, dag2 seeds; closed triangles, Ws seeds; closed squares, dag1 seeds.

(D) Germination in the dark with seeds not pretreated at 4°C. The histogram reports germination percentages scored on day 5.
