I consulted "The Reference Manual of Woody Plant Propagation" by M. Dirr
and C. Heuser, Jr., and came up with the following:
Amelanchier alnifolia - Saskatoon
Cuttings; softwood when new growth is several inches long. 3000 ppm
IBA-talc and mist result in good rooting. Late June (Canada) rooted
better than cuttings taken 2 weeks earlier or semi-hardwood cuttings
taken later. Hormone had no effect. A minimum of 3 roots per cutting
was necessary for survival.
A key to rooting this and subsequent species is timing. The currings
must be soft, taken well before the end bud has set. For most parts of
the U.S., late May into June would be the pak time.
Root cuttings would probably work on this species. Use root pieces 1/4"
wide and 2" long.
SEED: Should not be allowed to dry out, and should be stored in sealed
container at 41 F. 3 months cold stratification or fall planting in
secessary. The seed coat can become quite leathery and impervious. If
dried berries (entire fruit) are used, the fruits may need a warm period
(as much as one year) prior to cold stratification.

It says nothing about hardwood cuttings which I assume is what you have.
If you want to try them, the best thing is to use a higher strentgy
rooting hormone with IBA and take current year's wood (cut off any of the
previous year's). Dip the ends, and stick them deep into the rooting
medium, with just the tips exposed. Keep cool, moist, and wait till
spring. I haven't heard of doing much with hardwood cuttings with
anything in the rose family though. Still, you have the cuttings, can't
hurt to try it.
Root cuttings seem to be your best bet this time of year, if you can
actually get to the roots to take them.
