germination glucanase Figure 5. Relationship of the incidence of endosperm rupture to ß-1,3-glucanase content.

The data from Figure 4b and 4c are plotted as incidence of endosperm rupture versus ß-1,3-glucanase content expressed in pkat/seed for seeds treated with 0 (Control), 10-7, 10-6 and 10-5 M ABA. The solid line is a Hill Function fit of the data. The ß-1,3-glucanase content calculated for 50% endosperm rupture is ca. 3.4 pkat/seed.
