The centro-affine invariant conditions for Lyapunov stability of unperturbed motion in ternary differential systems with polynomial nonlinearities were determined and the centro-affine invariant conditions when a ternary differential system of the Lyapunov-Darboux form with quadratic nonlinearities have a holomorphic integral were obtained. On the base of the integral the stability of unperturbed period motion was studied.
