  The study of resonance production in pp collisions helps understanding
hadronization mechanisms and tuning the QCD-inspired particle production
models. In Pb--Pb collisions, resonances allow one to probe the temperature and
time evolution of the fireball.
  Transverse momentum spectra have been analyzed for $\kstar$, $\phir$ and
$\xstar$ resonances using data from pp collisions at 7 TeV collected by the
ALICE detector. A comparison with Monte Carlo event generators shows different
levels of agreement for meson spectra, while $\xstar$ is always underestimated.
