Self-consistent equation of plant cell growth.
We introduce a transcendental equation, describing the subsequent stages of plant cell/organ growth. Starting from empirically verified conclusions originating from the central limit theorem we also insert the influence of temperature on elongation growth to receive a time-dependent equation of growth parameterized by temperature. This self-consistent equation evolves with time using three cardinal parameters: t0, T0 and V0. They represent the time of maximum expansion rate, the growth optimum temperature and the corresponding volume, respectively. Experimental determination of these cardinal values enables evaluation of the dynamic extensibility coefficient Phi=PhiT(t) in time and temperature domain.
