Never tried that, I just sowed them straight from the pod and left them to it.
From knowing about other seeds, it could well work, though why one should snip off some of the tap roots I don't know.
Certainly keeping the sown seeds moist is good advice either way.
Magnolia seeds also need pre soaking to remove the 'soapy' covering.
