Inclusive momentum spectra of charged particles in three-fold symmetric three-jet (qqg) and two-jet +(qq) events taken from e+e- annihilation at center-of-mass energy of 58 GeV were compared. The spectrum of gluon jets was found to be significantly softer than that of quark jets with the same energy and topology.
