Based on SDSS data the nuclear activity statistics of the polar-ring galaxies (PRGs) was investigated. BPT-diagrams for PRGs and comparison samples were plotted and analyzed. Obtained results show evidence of excess of active galactic nuclei among PRGs compared to regular objects. Possible interpretation of such effect is discussed.
