The dynamics of 
spinor
condensates initially prepared in a double-well potential is studied in the mean-field approach.
It is shown that a small seed of 
atoms on a system with initially well-separated 
and 
condensates has a dramatic
effect on their mixing dynamics, acting as an effective barrier for a remarkably long time. We
show that this effect is due to the spinor character of the system, and provides an observable
example of the interplay between the internal spin dynamics and the macroscopic evolution of
the magnetization in a spinor Bose-Einstein condensate.
