Mike,
My advice is first check commercial
sources, NAFEX members, and local scionwood sales for varieties that you are
looking for. If you can’t find it through those sources, then a request
to one of the repositories could possibly supply what you are looking for. This
link will tell you the procedure for pears:
http://www.ars-grin.gov/cor/dist/dist.html
Corvallis will accept requests by e-mail. Here is the information you need
to supply:
Please group the items in your order by genus, and provide the
following information:
Name, Address, Phone, Fax, Email.
Statement of research interest/intended use of plant material.
Plant name and, where possible, inventory number.
Are you requesting seeds, cuttings, plants or in vitro cultures?
Copy of Import Permit with English translation (foreign requests).
Do you have any special needs or conditions? Timing? Packaging?
Will you accept Virus negative material only?
May we substitute duplicate clonal germplasm from a different source
of a similar seedlot in the case of species material?
They ask that you request 6 months in advance of the shipment date. Pear
scionwood ship in December and January, so get your request in early in the
summer.
I have been careful to request only varieties I can’t find
elsewhere. The only time my request was denied was when I asked for grape
cuttings. I live in Washington State, and importing grape
cuttings into the state without a permit is not allowed.
Hope that helps. Good luck.

in Corvallis WAS using old scionwood
Not quite on the same subject, but I
have noticed a variety or two at the repository that I'd love to have - can you
tell me what their policy is for getting scion wood?

Subject: RE: [NAFEX] using old
scionwood
Here is an update on
using some really old scionwood.
Sometime in the Winter of
2002-2003, a worker at the national pear repository in Corvallis cut some pear
twigs to fill a request I had made for scionwood. After a heat treatment
to minimize the chances of passing on some insect pest (I can’t remember
the problem), my scionwood arrive in late March 2003. I did a few grafts
that Spring, and the leftovers went into the veggie bin in the frig. The
were wrapped in damp paper towel inside a plastic bag. I did a few bud
grafts that summer. None of my grafts worked that season, but I hung onto
the wood. In December I cleaned out the frig, and the scionwood ended up
in the shed outside. I found the bag of wood around a month ago, and some
of it still looked OK. I decided to do some grafts and share the results.
April 2004: I had
run out of pear rootstock, so I grafted on seedling mountain ash that I found
growing wild in my neighborhood. From previous experiments, I knew pear
was compatible with mountain ash. I used a cleft graft I recently learned
from Leonard Jessen along with rubber strips and parafilm. After 10 days,
the buds on that old wood are starting to push through the parafilm!
From December through April, it sat in my shed on a shelf in the
dark where the temperature fluctuated between 35-50F. That wood was cut
almost a year and a half ago, and I some how managed to keep it dormant through
neglect. I’m glad I was the one that found these twigs because
I’m sure anyone else would have quickly thrown it out.
I won’t believe
these grafts have worked until the branches have grown a few inches, but so far
things are looking much better than I would have thought. The one that
looks the best so far is Sucre Verte…
“The
name means 'Sweet Green' in English. Origin obscure. Believed to have come from
Barmont, a chateau on the boundary of Burgundy. Described as early as 1598.
Well known in Paris by 1670. Fruit small in size, roundish-turbinate in form.
Skin smooth, glossy, intense green in color with inconspicuous dots. Flesh
white, fine, but with some grit at the center, buttery, juicy. Fairly sweet,
nut-like aroma, pleasing flavor. Early midseason. Tree vigorous, spreading in
habit, very productive. Moderately susceptible to blight.
- H. Hartman, 1957”

If it's alive and the grafts take, there is a good
chance that the scions could at least push some adventitious buds from the base
of the existing buds, even if they are dead. At very least, it's a way to
get some new information.
-Lon Rombough
Last
year was a crazy year for me. I had a big remodel done on my house.
Everything my family owned was either sent off to storage or packed into
a few small rooms untouched by the remodel. I had a bundle of pear
scionwood arrive last Spring that went unused. These were stored for a
time in the frig, but then I lost track of them in the construction mess.
Somehow they ended up in my shed. I found them yesterday while
cleaning-up. Some of the sticks were shriveled up, and most of the buds
look lifeless, but when I cut into some of the wood, I found green and healthy
looking layers.
My
question is would there be any point in trying to propagate this scionwood if
the buds are dead? It will be at least another year before I can get some
of these varieties again, but without buds on the scions I don¹t think I will
get a head start on just waiting for new wood next year. Any thoughts?
