Cane (Arundo donax) is not a bamboo but a sort of large grass. Even though
its morphology is indeed very different from that of trees, the grain
results from fibers running not exactly collateral in both. The fibers, some
of which carry water and sap-juices, some of which stabilize the stem,
contain more silica in cane and more lignine in tree wood. Also cane reed is
constructed with a particularily high order of fiber bundles (while in tree
wood they tend to be more chaotic). The grain that raises when the reed or a
piece of other wood ist moistend is the bundles of fibers that run at an
angle to the main axis of the reed face and surface at some point. They are
tougher than the surrounding matrix which consists of larger, short cells
and even empty space inbetween (intersticia).

Any Biologists or Botanists out there? Steve White and Ormondtoby have been
discussing 'grain' in reeds. I doubt if tree wood is a useful comparison
(though wood working techniques, like 'raising the grain' may be useful).
It may
be interesting for someone with a plant morphology text book to look up
bamboo
and tell us about how cane is put together. Knowing the relationships of
the
different parts of the cane may shed light on what is happening when people
do the different things they do.
