Some rare variety hardy seedlings
« on: January 31, 2019, 11:27:19 PM »
These are some seedlings I'm growing:
Kaffir lime, Yuzu, Ichangquat, US 852, one of them is a Thomasville Citrangequat and one is an N1tri


These are a Ventura Lemandarin (back) and Dimicelli seedlings that Eyeckr gave me. They're putting on new growth.



They're inside a grow tent.
(I measured the temperature difference and it's 7 degrees (F) warmer inside the enclosure than inside the room it is in)

Interesting that the cotyledons are above the ground. Was the seed on top of the ground?

Actually that pattern appears to be the norm for Ichangquat seedlings.
The seed splits open and rises just a little, and remains attached to the seedling.
As you can see, these split seeds have turned very green and remain an integral part of the seedling, but they are definitely solid and haven't turned into flat little leaves.
I haven't noticed this unique growth pattern on any other of the many different types of seedlings I'm growing.

For citrus, the type of germination (epigeal/hypogeal) is not marked.
If the seed is sown more than 1 cm in the soil the germination will be hypogeal.
If the seed is sown less than 1 cm in the soil the germination will be epigeal.

Why don't you paint the pots black?
Roots when they see the light stop growing, also algae can set inside the pot when exposed to light and humidity.

Keraji



From the research I've been able to find, I have been able to piece together that Keraji probably came about over time as a triple backcross of Kunenbo with Shikuwasa (that is being repeatedly crossed with Kunenbo).
Kunenbo is the male pollen parent of the well-known Satsuma mandarin variety, while Kunenbo itself is a large almost orange/tangelo-like mandarin that apparently has some pomelo ancestry in its lineage.

Keraji is quite cold-hardy, supposedly being able to survive down to perhaps 12 to 14 degrees Fahrenheit.
However, from my experience trying to grow the small seedlings outside (on their own roots) in zone 8a in the Pacific Northwest, I can report that they barely seemed to survive through a cold period with lots of snow that included what I believe was a low point of perhaps 16 degrees. Die-back on many of the small branches. (They would probably do better further South, and grafted onto trifoliate)

Here are my seedlings.

These are dunstan citrumelo seedlings from three different fruits. The once in the round pots seem to be hybrids. I was pollinating the flowers with pollen from my i x s. It looks like I was successful on one flower.  :D


The hybrid seeds came from the strange looking fruit.



Here are some thomasville and keraji seedlings.

I've read that Dunstan has much better taste than Swingle citrumelo.
My Dunstan is surviving outside, though has not fruited yet.

how many months those seedlings are?
I have poncirus sprouted in December now it's 10-12 cm high, they grow pretty fast. Whereas Oroblanco grew rapidly in the first two weeks then stopped.

I made some micrografts onto Flying Dragon.
Ichangquat (top graft) and Keraji (bottom graft).



I'm not very good at grafting so I don't know if the tiny grafts will take.
I found the Flying Dragon at the local nursery, it was kind of expensive though.

You can take pt cuttings and root them. Some people report hard to root. I have success 100%. In 4 weeks they start to grow roots.

I haven't done Citrus grafting recently, a procedure that worked very well was a side bark graft when the rootstock cambium was slippery and moist. I made a shallow downward cut just under the bark, trying not to harm the underlying wood. Next, I selected the thinnest, flattest scion I could find and shaved the outer layer of both flat sides of the scion, exposing, but not removing the cambium. Then slipped it under the bark flap I had created. Due to the thin scion there was very little bulge after insertion. Next I wrapped the graft area, being careful to match the wrapping tension to the robustness of the grafted tissues. Tender parts needed less tension, thicker required more.

This was very successful for me, on the other hand persimmons with cold damaged cambium were pretty much impossible to get to succeed.

lebmung, nice looking cuttings, were they rooted at the point they were photographed?

Looks amazingly similar to the young  poncirus seedlings.

Sorry those are seedlings 3 months old I forgot to mention.
I keep the cuttings in a small greenhouse with temperature controlled. But they look quite the same.
There is a video on youtube where citrus fruitmentor doesn't have any success with rooting PT. I guess he's done something wrong. I root all citruses without problems.

C. ichangensis and Citrumelo root easily, Mandarins and PT do not. But I admit I never use any technical devices like root heating. Just stick Wood in the ground.

It is strange that very few to no one, has any success rooting PT, not even a pro like Fruitmentor but Lebmung has 100% take.

In the past, I propagated several thousand rooted cuttings (not citrus}. There are many factors that contribute to the success or failure. One clone may be easier than another. Optimum seasonality (Time of year) can be extremely important. Just as transitioning from juvenile stage to mature stage is required for flowering and fruiting, the ability to root decreases with maturity. In general, more juvenile is better. Some species are maintained in a continuing juvenile state by repeatedly cutting the mother plant almost back to the ground to force new easily rooted shoots. I don't know how much this applies to Citrus.

Additionally, hormone treatment can have a big impact on success.

I never tried to root them, but apparently it is possible in the case of summer softwood cuttings from juvenile immature plants at higher temperatures and  high humidity

I tried to root about 100 cuttings of Prague chimera, from a mature tree.
It took a long time but one by one they all eventually died.
And now I read ... cuttings collected from mature trees in all months ... failed to form callus and root. !

I didn't intend to offend anyone. I saw the video online and it seemed challenging to me. I usually root any plant.
So I said let me experiment.
4 weeks they grow roots and new leaves.
Yes I control the temperature and humidity. And do use a mixture of hormone plus a lightly fertilised sterile medium.
Here is the proof.
