Abstract

This present work is modelling the three physiological stages of germination. The aim of modelling is to define within germination time the duration of the different stages and their temperature dependence. The periods follow Arrhenius-type relations with (average) activation energies typical for the given stages and according to the germination time as well. The germination time being different seed-by-seed can be considered a random variable of normal distribution according to the model. The result of the model was controlled by experimental data given by seed germination trials of the common reed ( Phragmites australis ) and in cases using those given on other seeds (rice, pea).
