GA Represses Cytokinin Responses.
Wild-type (Columbia) seeds were germinated on vertical (A) or horizontal (B) Petri dishes on MS media with or without BA (B), GA3 (G), or both (B + G). After 10 d, root length (A) and anthocyanin content (B) were measured. The results represent an average (±se) of 60 seedlings grown on three different plates (20 seeds per plate). The experiment was repeated three times with similar results.
