Abstract：
In this paper we found that the final state hadron multiplicities in Υ→3g fragmentation satisfy the same general mass dependence as in e⁺e^－→q₀q₀ events. This indicates that the fragmentation of quarks and gluons to hadrons follows the same mechanism. The important character of increment of the baryon multiplicity in Υ→3g fragmentation is interpreted naturally without any other assumptions.
