The position of the embryo in the seed coat is more or less determinate, so
that the radicle has a characteristic orientation to the seed coat. Thus it
would not be surprising if the rule were generally true. The best position
relative to the radicle, though, could vary widely among species.

Try the new - I almost always find at least one solid hit on
the first page of search results.
