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 E. umbellata (average and standard deviation), for all provenances and treatments (number of mother plants: north and center = 0). Different letters indicate significant differences between provenances within treatments, at α = 0.05, according to the Mann–Whitney U test and Student’s t test for germination percentage and T90, respectively
