Note: 1physiological quality describes viability () and germinability () in the sample: high physiological quality is related to a diaspore sample with viability () and germinability () higher than 90%, intermediate physiological quality is a diaspore sample with and , and low physiological quality is a diaspore sample with and ; is a parameter of Fick’s second law from a data set to perfect fitting and, hence, without variability measurements. The values of and represent the average (lower confidence interval; upper confidence interval) obtained from 1 000 Monte Carlo simulations at 0.05. diaspores.
