dc.description.abstract The hadronic fragmentation functions of the various quark flavours and of gluons are measured in a study of the inclusive hadron production from Z0 decays with the DELPHI detector and are compared with the fragmentation functions measured elsewhere at energies between 14 GeV and 91 GeV. A large scaling violation is observed, which is used to extract the strong coupling constant from a fit using a numerical integration of the second order DGLAP evolution equations. The result is αs(Mz) = 0.124+0.006-0.007 (exp) +/- 0.009 (theory) where the first error represents the experimental uncertainty and the second error is due to the factorization and renormalization scale dependence.
