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.展开更多

And established the thermokinetic equation for the process of cell growth inlilbited by the products of metabolism, as:From this equation, the rate constants of cell growth k [= k0(1 - β’ P0)] were obtained.This thermokinetic equation is very suitable fdr cell growth of separated culture and is very important for the study of bacterial limited growth and their characteristics.展开更多

The thermodynamics and kinetics of the rice mitochondrial metabolism out of the cell have been studied. The metabolic thermograms of the rice mitochondria show different stages. If the rice mitochondria have been laid up for different times, the metabolic thermograms and kinetic behaviours of the rice mitochondria are different. Some thermodynandc values and kinetic parameters, as well as some new experimental thermokinetic equations in the actiyity increasing stage of the rice mitochondria,have been calculated and established. Furthermore, the thermodynamic and kinetic behaviour of the rice mitochondria in the metabolism out of the cell under changeable and low temperatures have been approached preliminarily.展开更多

We have also derived the thermokinetic equation for the process of bacterial growth, which was untypical "S" , unideal growth, as:From this equation, the rate constants of bacterial growth k wore botained.This thermokinetic equation is very suitable for cell growth of separated culture, in which the thermogenesis curve is untypical. The model propoted by equationl(1) has been compared with the exponential and logistic models. This thermokinetic equation is very significant for the study of bacterial limited growth and their characteristics.展开更多
