Pollen germination percentage in response to incubation time (hours) in quinoa QQ74. Sample sizes are n = 2 for 1 h of incubation, n = 8 for 18 h of incubation, n = 4 for 24 h of incubation, n = 7 for 48 h of incubation, and n = 5 for 72 h of incubation. Letters above boxes indicate significant differences from Welch's t-test (p-value < 0.05)
