 The thermograms of the germination and growth of rice and tree seeds were determined and studied by using a newly constructed microcalorimeter build in this laboratory at Wuhan University. The thermograms show the existence of physiological triphasic patterns (including imbibition, activation and growth stages)in the germination and growth process. Nonequilibrium thermodynamics of the germination and growth of seeds was considered under given conditions, and the thermodynamic functions of the germination and growth of seeds were calculated.

Key words: Seeds, Germination and Growh, Microcalorimetry, Nonequilibrium thermodynamics
