From: Germination in five shrub species of Maritime Pine understory—does seed provenance matter?
Germination percentage (left) and time-to-germination of 90 % of the final germination (T90; right) for P. tridentatum (average and standard deviation) for all provenances and treatments (number of mother plants: center = 10, south = 5). Different letters indicate significant differences between provenances within treatments, at α = 0.05, according to Tukey’s test for germination percentage and according to Student’s t test for T90
