  We suggested that longitudinal polarization of Lambda produced in e+e-
annihilation at LEP energies can provide useful information on hadronization
mechanism in general and on testing the validity of different pictures for the
spin content of baryon in describing the fragmentation process in particular.
We present the results obtained from the calculations based on two very much
different pictures.We compare the results with the recent ALEPH data and make
suggestions for future measurements.
