The paper presents a computational approach for modeling the germination process in relation to water potential according to Gummerson and Bradford's hydrotime concept. The procedure is based on a generalized linear model with a probit link function. In order to present the model process in a population, the data were simulated. Successive computational steps led to informative results and a graphical presentation.
