Figure 5.  The effect of GA biosynthesis inhibition on the time courses of testa rupture and endosperm rupture of Arabidopsis thaliana (A) and Lepidium sativum (B). The incidence of testa and endosperm rupture was scored with time after the start of the incubation at 18°C (Lepidium) or 24 °C (Arabidopsis) in continuous light. Medium without (control; CON) or with the GA biosynthesis inhibitor flurprimidol (FLU; 10 µM for Arabidopsis, 100 µM for Lepidium) added. Mean values ± SE from one experiment with at least three plates with 50 seeds each are presented.
