Seed germination rate and Germination Speed Index (GSI) of Dyckia rariflora in MS medium modified for salts (50% = 0.5, 100% = 1), PVP (0 = absence, 1 = presence) and sucrose (g). The error bar represents the means ± standard deviation, and different letters indicate significant differences between treatments after a Tukey test (P < 0.05)
