Cutting Info--Online, Location of cut on stem, Pulp removal

Good Morning,

RE: Online Search--The UC DAVIS Rooting Database was mentioned recently
either here or 
the Alpine-L list.
URL is http://telework.ucdavis.edu/root/pchome.htm
You can search by genus or cultivar.  Has good basic information.

RE:Dirr's book--very good.  I highly recommend it ot al serious woody plant
propagators.

RE: Location of cut on stem.  Such information is scattered in the
literature unfortunately.  Many references may remark on this topic when it
is critical to success but don't count on it.  Best thing to do would be
for those who have solid experience with a plant, where location of the
base of the cutting in relation to the node is critical, to send such info
to the UC Davis Rooting Database folks for inclusion.

IMHO, rarely will you ever go wrong having a node at the base of a cutting.
 There are those plants that will root exclusively or nearly so only in the
node region and never in the internodal zone.  With these plants, a segment
of internode left below ground will rot, thus posing some pathological
problems.  

From a professional point-of-view (mine) it wastes material and is way to
time consuming to have to cut each and every cutting (when doing 100's to
1000's) to trim the excess internodal material off both above ground and
below ground.  Thus if it isn't absolutely necessary....then I don't,
particularly when it comes to the basal end of the cutting (part stuck into
the medium)

RE: fleshy seed pulp.  I have used a mix of bleach and water, usually 1
part bleach to 9 parts water, or a little stronger to remove pulp and
surface sterilize the seeds.  If fruit has an extremely waxy surface you
first must mush the fruit up a bit,  Often in the fall I will collect
berries of various trees/shrubs, toss them in a zip-lock bag in the
refrigerator and leave them....perhaps mushing them a bit....and let them
"ferment" a bit to soften the pulp.  Then when they are really soft and
disgusting, I rinse off as much as I can then  I clean with the bleach
solution, leaving them in till the pulp pretty much turns white and or
disappears.  Rinse very well (usually soaking in clean water for 10 to 30
min to remove most all the bleach solution.  Then either they are
stratified (simply moist in a clean ziplock bag in the frig or sown.  This
works very well for Sorbus (Mt. Ash) and most all temperate woody fruits I
have tried.

Hope this if of some interest and help.
Best Regards,

Scott
