[Growth, elastic and inelastic deformations in morphogenetic processes].

On the basis of rheological equation of standard body (as a physical state equation) the stress relaxation or deformation delay (the creep) accompanying the growth of adjacent layers (the model) or the growth of acetabularia apex are studied. It is shown that both initial geometrical characteristics of elastic and viscoelastic deformations determine final morphogenetic complication of bioconstructions, while time characteristics of deformations--the viscosity parameters of growth. Additional morphogenetic switching of development occurs during abrupt (of the phase type) changes in materials states resulting, among other things, from metabolic catastrophs. And vice versa, "catastrophic" changes in the shape of the morphogenetic system affects the course of metabolic processes.
