Note: 1physiological quality describes viability (V) and germinability (G) in the sample: high physiological quality is related to a diaspore sample with viability (V) and germinability (G) higher than 90%, intermediate physiological quality is a diaspore sample with 61% ≤ V ≤ 89% and 51% ≤ G ≤ 89%, and low physiological quality is a diaspore sample with V ≤ 60% and G ≤ 50%; D/ρ2 is a parameter of Fick's second law from a data set to perfect fitting and, hence, without variability measurements. The values of vm and a¯ represent the average (lower confidence interval; upper confidence interval) obtained from 1 000 Monte Carlo simulations at 0.05. n = 50 diaspores.
