Fig. 3. Cumulative germination for Myrsine parvifolia seeds over 30 days of incubation at 20/30 ̊C (12 h:12 h) thermoperiod. Seeds were from the 2009/NC batch (non-cold storage) and were subjected to the addition of gibberellic acid (GA3) or scarification of the seed testa in relation to the untreated (control) seeds (n = 4). Mean values of final germination (%) of the treatments are shown. Different lowercase letters among means show significant differences (p <0.05), according to the LSD test.
