英文摘要	The production rates and the inclusive cross sections of the isovector meson pi(0), the isoscalar mesons eta and eta'(958), the strange meson K-S(0) and the Lambda baryon have been measured as functions of scaled energy in hadronic events, two-jet events and each jet of three-jet events from hadronic Z decays and compared to Monte Carlo models. The analysis is based on 3.7 million hadronic events collected with the ALEPH detector at LEP at a centre-of-mass energy of root s = 91.2 GeV. The JETSET modelling of the gluon fragmentation into isoscalar mesons is found to be in agreement with the experimental results. HERWIG fails to describe the K-S(0) spectra in gluon-enriched jets and the A spectra in quark jets.
