  Valence quark distributions in transversally and longitudinally polarizied
rho mesons in the region of intermediate x are obtained by generalizied QCD sum
rules. Power corrections up to d=6 are taken into account. Comparison of the
results for pi and rho mesons shows, that polarization effects are very
significant and SU(6) symmetry of distribution functions is absent. The strong
suppression of quark and gluon sea distributions in longitudinally polarizied
rho mesons is found.
