Abstract

The germination kinetic of seed can be used to judge the seed activity and provide experimental basis for the seeds breeding. However, the research of seed germination kinetics has been paid less attention. In the present study, the expression methods of seed germination rate and kinetics are summarized. The growth rate of seed can be expressed as fresh weight, dry weight, root length and bud length, respectively, and the rate equation has been provided in detail. The kinetic models of seed germination can be expressed by the first-order kinetic equation, Elovich equation, Langmuir equation and double constant equation. The meaning of parameters and the usage of models are discussed.
