In this paper, we investigate the development of cosmological perturbation in early time in modified gravity of f(R) of polynomial exponential form. Results show that there is a difference that can be observed in the development of perturbation in the model from that in standard ΛCDM model. Growth index of universe γ(z) also be obtained in the paper and shows that it differs from that in ΛCDM and also is consistent with observations. Key words: cosmological perturbation; polynomial – exponential form; modified gravity; growth index of universe
