Using two volume-limited Main galaxy samples
of the Sloan Digital Sky Survey Data Release 10 (SDSS
DR10), we examine the environmental dependence of
galaxy age at fixed parameters or for different galaxy families.
Statistical results show that the environmental dependence
of galaxy age is stronger for late type galaxies, but
can be still observed for the early types: the age of galaxies
in the densest regime is preferentially older than that
in the lowest density regime with the same morphological
type. We also find that the environmental dependence
of galaxy age for red galaxies and Low Stellar Mass (LSM)
galaxies is stronger, while the one for blue galaxies and
High Stellar Mass ( HSM ) galaxies is very weak.
