Figure 7.

Growth of wild-type, gai, and gai spy-7 gar2–1 plants on germination medium (Valvekens et al., 1988) containing different concentrations of PAC (A, 0 nm PAC; B, 0.5 nm PAC; and C, 5 nm PAC) and GA₃. Seeds (15–18 seeds for each sample) were sterilized, placed on appropriate medium, chilled for 7 d at 4°C, and then grown at 23°C with an 18-h photoperiod. For each of the three genotypes, three representative plants (22 d old) are shown for each treatment.
