Yuri,
I never know whether you are 100% right either, but what is it that you
would be grafting to a blind tuber that would cause the blind tuber to
produce a copy of itself, unless it were a growth point from another
tuber of the same variety in which case what’s the point?
Anyway, since you raised grafting as a topic, I did a little research
thru my files and located a copy of an article from the March 1986 ADS
Bulletin which describes tuber grafting as well as stem cuttings which
you completely overlooked in your reply to Teresa. Then I called Norma
and Mac Boyer who are working on scanning old ADS Bulletins and they
provided me with a scan of this ADS article which I have attached.
Actually, I have attached two copies of the scanned article. One is in
.JPEG format and the other is a .GIF version of the .JPEG scan. I
would be interested in feedback on the quality of the two versions as
they both represent a substantial reduction in byte size from the
original Boyer scan.
As for tissue culturing, or micropropagation, as I think it is formally
called, there is a book called 'Plants From Test Tubes' from Timber
Press <http://www.timberpress.com/books/isbn.cfm/0-88192-361-3 > that
provides a great overview and introduction to general micropropagation
techniques. My take on the subject was that the cost of a sterile
environment put micropropagation beyond the reach of this hobby dahlia
grower.
I also believe that micropropagation generally requires that you start
with an explant that contains some meristem tissue. In the case of a
dahlia this would be the tip of a bud, branch or sprout. I don't think
a few cells from anywhere on a blind tuber will get the job done.
Anyway, lets share that illustration of a Russian dahlia scion because
I can't seem to find the illustration that I recall seeing.

If you can possibly make it the weekend before Labor Day, or Labor Day weekend, this is the time to go. It is their annual open house and as well as the open fields, they have over 100 professionally done floral arrangements using their dahlias. It is an incredible site! They have food and seminars all day. As far as places to stay, I'd just do a search on Google for Canby, and you'll find places. Mingus Dahlias and Helen's in Vancouver about 1/2 hour north, both have open fields all the time. I know there are others as well, but can't think of them. I would allow about half a day to really see the fields and arrangements.

We grow all our cuttings in pure sand in cups with holes in the bottom
& sitting in a tray in about 1 1/2" of water. You can also grow
cuttings in water only- hydrophonically. So you don't have to keep
cuttings dry to have them root. Cory
Aaron, if someone had a very nice valuable new introduction, and a nice clean
lab to do the work in, making lebbinty lebben hunnert plants could be a very
profitable enterprise. Sure would be faster than letting nature take its
course. And Yuri, could I have the name and author of this book? You never
know but that a version is pining away in some obscure library waiting for
someone like me to stumble upon it. Tex

Sounds like a good experiment for someone with time, dedication and room to do

I agree with the abuse/chop for a fat tuber with no eye. I'm not so sure I'd risk it with an eye showing. The late bloomers are often a pain for me because they are so slow....... I usually give up on them after trying for a couple of seasons.
I was a bit slow myself realizing that radical surgery is possible on dahlia tubers. When the tuber is too large for a pot, I now cut off the end, let cure, and then plant it in the pot.

Actually, you are not 100% right. For two reasons:
1. I have a Russian book about dahlias that illustrate
how you can graft (!) a dahlia cutting to a tuber without an
eye.
2. I am sure you can get a dahlia plant from an eye-less

A dahlia tuber cannot grow if they do not have an "eye". It is so disheartening to me, sometimes, to have a big, beautiful plump tuber and have to throw it away because there is no chance it will grow without an eye. That is their growing point.
Perhaps a third point. So far 100% of the tubers with lazy growing sprouts I suspected turn to be rotted. That why I write the vender's name along with the tuber name so I can go back to the vender for replacment.

I sometimes get a "lazy" tuber, in that it is large,and full of stored
energy. So Mr. Tuber just perks along on stored energy and takes it sweet
time putting out feeders. If I have a really big fat tuber, I chop it down
to a more normal size, let it heal a bit, then plant it. Tex.

Ualani, I lift my dahlias
in the Fall (October 15-31). For winter
storage. Prior to storage, I divide the clumps,
dip the bunch of tubers in a solution of bleach/water, let dry overnight then
store in plastic supermarket bags....... with some vermiculite in a cold
room. If I wanted to start a big bunch of dahlia plants for
the next season, I would get at the job in March (maybe earlier)....... for
growing under lights and finally planting out that
June. Cuttings started too late and planted out very
late risk under-development of tubers and poor storage quality afterwards.

I am going to try propagating some tubers
in the fall from cuttings - I've always wanted to do that.
