In both upland cultivars, seeds incubated at 15/30◦C exhibitedhigher TGP means compared to seeds incubated at 30◦C in solutionsof the same ABA concentrations. In both lowland cultivars, this wasthe case when the ABA concentration was low (10 M); however, atthe highest concentration (50 M) TGPs were statistically similar,approaching low values (Table 2).
