The effects that interactions produce on galaxy disks and how they modify thesubsequent formation of bars need to be distinguished to fully understand therelationship between bars and environment. To this aim we derive the barfraction in three different environments ranging from the field to Virgo andComa clusters, covering an unprecedentedly large range of galaxy luminosities(or, equivalently, stellar masses). We confirm that the fraction of barredgalaxies strongly depends on galaxy luminosity. We also show that thedifference between the bar fraction distributions as a function of galaxyluminosity (and mass) in the field and Coma cluster are statisticallysignificant, with Virgo being an intermediate case. The fraction of barredgalaxies shows a maximum of about 50% at $M_r\,\simeq\,-20.5$ in clusters,whereas the peak is shifted to $M_r\,\simeq\,-19$ in the field. We interpretthis result as a variation of the effect of environment on bar formationdepending on galaxy luminosity. We speculate that brighter disk galaxies arestable enough against interactions to keep their cold structure, thus, theinteractions are able to trigger bar formation. For fainter galaxies theinteractions become strong enough to heat up the disks inhibiting bar formationand even destroying the disks. Finally, we point out that the controversyregarding whether the bar fraction depends on environment could be resolved bytaking into account the different luminosity ranges probed by the galaxysamples studied so far.
