| Abstract: | In this paper,a Sunflower equation with periodic perturbations is studied.In particular,the existence of subharmonic bifurcation solution is discussed under the condition that excitation frequency and the critical natural frequency of Hopf bifurcation are two-order subharmonic resonance.Furthermore,the stability of subharmonic bifurcation solution is also discussed. |

| Keywords: | Sunflower equation subharmonic bifurcation stability |
