We report the 73Ge-NQR studies on the antiferromagnetic (AFM) heavy-fermion compound CeNiGe3 which shows two domes like pressure-induced superconducting phases in the pressure (P) ranges of 1.7-3.5 GPa and 5.9-7.3 GPa denoted as SC1 and SC2, respectively [M. Nakashima, et al., J. Phys. Condens. Matter. 16 (2004) L255, H. Kotegawa, et al., J. Phys. Soc. Jpn. 75 (2006) 044713]. The NQR spectra have revealed a change from an incommensurate AFM structure at P = 0 and 2.0 GPa into a commensurate one at P = 2.8 GPa. The onset of the SC1 may be relevant to an intimate evolution from the incommensurate into commensurate AFM-spin structure as P increases.
