  New results on inclusive production of Sigma^- and Lambda(1520) and on proton
production in quark and gluon jets are presented. These results are based on 2
million hadronic Z decays collected with the DELPHI detector at LEP. They are
compared with the results of other LEP experiments and with models. It has been
shown that the total production rates of all light-flavour hadrons measured so
far at LEP 1 follow phenomenological laws related to the spin, isospin,
strangeness and mass of the particles. A significant proton enhancement in
gluon jets is observed, indicating that baryon production proceeds directly
from colour objects.
