Been offline for a bit.

The Epiphyllum and Hylo grafts are coming along at various rates depending on the seedlings used.

Quite some variation within the seedling grafts, the outstanding seedling shown in https://garden.org/thread/view... is now just under 1.2meter, pleased.

There have been three Epi seedlings grafted, one was too small and has been replaced with a hypocotyl hylo seedling, still there but not looking too hopeful.

One of the Epi offsets was cut off and had a hypocotyl hylo seedling added to see if the Epi could be used as a rootstock.

Cheers

Had a thought about using Pereskiopsis leaves as rootstocks rather than either Pereskiopsis plants or Schlumbergera cladodes.

So I grafted an hypocotyl seedling scion to a Pere leaf.

Notice the grafted leaf, no cutting powder used, and the dead leaf where cutting powder was used.

It seemed to take but no sign of growth seen. Reasoned that maybe the lack of roots and so tried using commercial cutting powder, NAA and IAA, not good, killed the leaves.

While I was offline looked through some of the earlier data collected on Grafting and Pereskiopsis finding mention of rooted Pereskiopsis leaves. I then searched to see if there had been any developments in addition to the notes I already had.

Best/most interesting were Page 1, Page 2, www.shroomery.org and of related information, Cactiguide.com. Will be trying some of the methods used mentioned in the links shortly.

Cheers

I doubt the pere leaves will be able to propel growth on the seedlings. Can you see union formed? I would have thought that leaves don't have the vascular bundles and cambium necessary for the graft to take. IMO. I do know that there is a mass propagation technique for pereskiopsis, where you take a stem, and cut it up into small pieces. Ideally these small pieces all have 1 leaf, and one areole. These can be rooted, and will produce a shoot from that one areole.

There is definite a vascular bundle, time will tell if a union occurs, one lives in hope.

Yep have seen that and have some hopefully developing roots.

Came across an interesting article well worth a look.

Had another look at the Pere leaves using a magnifying glass.

In both the tip section cut and the middle section cut, there is a distinct line(had used light green but that was hardly visible so changed the color).

In the tip cut there are three darker green dots with the center dot being in line with the tip.

I take these to be vascular bundles but would need a microscope to be sure.

I have placed the scion on the central bundle, we'll see what eventuates.

Light rain here today, I did two more hypocotyl scion grafts this time to leaves still attached to the plant.

Will see in the morning if they have survived. (They didn't)

Cheers

Came across this old post yesterday, adds to the list of possible rootstocks.

Have one Rhipsalis, unknown species, possibly a hybrid, and grafted one of my Hylo hypocotyl scions to a cladode.

Subject: Grafting Seedlings with Rhipsalis
Message-ID: <[email protected]>

I would just like to report that I am now the happy owner of a
Turbinicarpus successfully grafted onto a Rhipsalis species.

The Rhipsalis species I used, of which I am uncertain of the species
yet, is an epiphytic cactus that is commonly sold as a hanging
basket plant and is fully cylindrical in form, unlike some of the
genus. Interestingly enough I saw a number of what I think were the
same species at Home Depot recently.

I took a clipping of a youthful succulent section at maximum
diameter (5 to 6 mm) and cut about a four inch section off. Using a
sterile cutting tool I did the graft with a 4 mm plant and placed
the uncalloused base of the Rhipsalis in moist soil and have had no
problems with root rot. The grafted scions, which had no device to
hold them down or in place besides the two plants' own fluids, were
then covered with a baggie to maintain air moisture until the grafts
obviously took. The take off in growth on the scions is slow, but I
attribute this to the need for the base to form a stronger root
system. The roots formed quite quickly. I intend to root some 4"
sections prior to grafting to see if growth will start at a higher
pace this way.

Rhipsalis plants are widely available and will likely prove a viable
alternative to Pereskiopsis for the grafting of small seedlings for
which Pereskiopsis is often used but for which can be difficult to
locate except for orders from cactus specialist. Rhipsalis is a
hanging plant and grows like wildfire and the small 4" sections
needed for grafting stand up straight for grafting with ease. With
time I will see how long the stock, both health-wise, and
weight-wise, will last before removing the scion becomes necessary.
Growth rates will also be gauged.

Cheers

Came across this page, Dragon Fruit: Using Pro-H in V-Grafting. Expedite the New Growth. recently.

A very different approach to V grafting. Did leave a comment asking what auxin/s(NAA and or IBA) were in the solution, disappointed to find the comment had been deleted.

Searching led me to an interesting explanation of the Guttation phenomenon but could not find the product mentioned.

Am fairly sure it would contain IBA and there are reasonably priced gels available here. Intend to purchase some and see if my suspicions are right.

The result of the demonstrated technique are impressive.

Cheers

Further to yesterday's post.

Same people are also using a "Flower enhancer", results are quite dramatic.

Dragon Fruit: Follow-up with Pro-H used to stimulate Flowers. Unexpected Results.

They have also identified the source of both the Flower enhancer and the Pro-H promoter.

You should look, it's amazing.

Update since https://garden.org/thread/view...

This is the Star Performer. It has done better than I had hoped especially seeing we are moving into Winter at a rate of knots, cold, wet.

Raining at the moment with more forecast for the next few days.
Pleased with the growth of the Epi scions. The very small scion from seedling 3, failed, it has grown more and I will wait till a large enough scion can be taken before trying again,

Sorry about the photo size, Optus has been a real Pita lately.(You'll need to decipher that yourself, it's certainly not complimentary.)

Cheers

The Epi scion on Hylo hybrid has grown substantially. Decided to graft a Sjaan scion to a mid-sized cladode on the large scion.

Be interesting to see if it takes and grows during the winter. Certainly the cold, our first ice producing Frost two days ago, has not slowed down the two Epi seedling scions, growth.

Will be away from the site for some time, back as soon as practical.

Cheers

Thank you for sharing these unusual exploits! Take care until your next visit with us. ; )

Thanks, will still be away but if I see something really worthwhile, will post it.

Re https://garden.org/thread/view...
The graft used a rooting gel, 8g/L Indole-3-Butryic Acid, which has not proved useful.

Tried again same scion donor but on the Hylo Hybrid carrying the Large Epiphyllum scion.
Was a bit concerned because of the size of the scion, some wind, light rain forecast, need not have been concerned.

Cheers

Have put together a solar heated healing area for small grafts.

Amount of water loss through evaporation, can to a large extent, be controlled by floating an appropriately sized plastic sheet on the water holding area.

There are two grafts on Pereskiopsis, one Echinopsis the other a Selenicereus X NOID Hylo being used to test the setup.





Will make some improvements by using a small Chest Freezer for the next iteration.

Cheers

My Sjaan Epi scion graft is causing me some problems, it has just failed again.

This time I used the Pereskiopsis leaf method which has been most useful in a number of different scion grafts, the Sjaan is an exception, to the rootstock used.

Pereskiopsis technique has failed in a Sjaan scion to the Padre X Kiwi Legend scion and now to the Hybrid rootstock which has had a number of different, successful seedling grafts.

Clearly the Pereskiopsis technique is not a panacea.

Cheers

Spring here now, there's movement at the station.

I've had to tie up some of the scions, the Epi scions in particular.

It's not unthinkable there may be flowers on scions of approximately 10mm, grafted in early January.

Follow the Yellow Brick Road on the most outstanding Hylo scion.

Nearly all scions are busy producing new shoots which will be put to good use if the scion producing them, turn out to have some potential.

Have grafted two Cereus seedling scions to the plant in the past week, they appear to have taken but it's early days.

Unfortunately some Chauncey scions have not survived nor have a couple of Sjaan scions. Frustrating given the excellent results with the Padre x Kiwi Legend seedling scions.

Cheers.

Have been looking around for Pereskiopsis to Opuntia grafts without success so decided to do one to O. robusta.

Used two scions neither of which have started visible growth yet, one with leaves, the other with none. So far Pereskiopsis in field situations have yet come out of winter dormancy.



Looking forward to any development.

Cheers.

Been looking around for grafting ideas. Tremendous number of outside of the box ideas.

There are two sources, which despite the language barrier, are of sufficient interest to post links to.

They have unique propagation ideas as well as approaches to grafting but most importantly, the results are posted in many cases.

Hope they are found to be useful.

This is a regraft of Pereskiopsis, trying once more.

Also showing a Succulent leaf(?) with roots and a shoot. The shoot appears to be close to a carbon copy of the shoot on the Succulent leaf held by a spine, grafted to the same O. robusta cladode.
