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 ; 2, where and are parameters with statistical significance () by hypothesis testing based on confidence intervals at 0.05 significance () (: estimative for velocity for each germination phase; and : initial velocity and increment or decrement of velocity for each phase in relation to time ()); 3chi-squared value () was lower than the theoretical value at 0.01 probability () indicating that model regression has a goodness of fit at 0.01 significance () to describe each germination phase; 4germination phases were determined from an algorithm, which detects great inflections from velocity and acceleration curves. diaspores.
