Here is a listing for tension:

This is for pine, not hickory, but it does list tension parallel to the grain:

This one lists many woods, including Hickory, but NOT tensionat all:

You may be able to use the second reference to compare pine to hickory and get a ballpark tensile value for hickory.

This link lists general properties and has some interesting data, but no numbers:

http://www.extension.iastate.edu/Publications/PM329.pdf

This one states that "Due to difficulties in testing and the limited use for such data, tension parallel to the grain has not been extensively measured and/or reported to date." :
