My citrus spent the winter in a dark basement. To give them some light, I installed a simple led flashlight and connected it with solar panel. Every day they received 1-2 hours of white light. Nearly no watering. No heating. The lowest temperature in the basement was about 0 °C, possibly -1 °C. The highest measured was about 6 °C. They spent three months underground.

Most of them did fine, except for the most frost sensitive like citron and lime. Satsumas, kumquats and ichangensis didn't lose a single leaf.

Usirius, the flowers on your plant look very similar to these of citrangequat 4 saisons.

High grafting on trifoliate is advised by J. Stewart Nagle in Citrus for the Gulf Coast. It is said to reinforce winter dormancy of the entire plant.

PDXIan, how do the first two leaves of this seedling look? Are they round and paired like in most citrus seedlings? Or smaller and unpaired? - that would indicate fingerlime parentage.

Prague leaves display an interesting chimeric pattern before dropping. Almost like a variegata ;)

Mikkel, the seeds that I planted unfortunately rotted. I also sent some seeds to one man, and he had success with germination.

To me it looks like Hualongbing (citrus greening disease).. A deadly disease originating in Asia.
But I have no personal experience with HLB, so let's wait for an expert in that matter.

Cold Hardy Citrus / Re: Large poncyrus fruit!
« on: October 28, 2018, 05:39:21 PM »
For me, a Poncirus fruit with a diameter of 5-6 cm is big.

I've made this photo recently, for comparison. The bigger fruit comes from a standard PT and is 5 cm in diameter. The smaller ones come from a Flying dragon plant and are 3-4 cm in diameter. I've also seen standard PT plants with such small fruits. So there are definitely differences in fruit size depending on the particular plant/cultivar.

Yes, cracking of the bark was the main problem.
I wonder how does N1tri compare to Ichang papeda in frost hardiness. I have a small grafted IVIA ichangensis, maybe I'll test it inground when it gets older.

I can confirm that N1tri has good frost hardiness.
Last year I planted it inground to see what happens. For the winter covered it with white agrotextile. Winter proved hard, with a minimum of -21 C.


After the winter N1tri was severely damaged but some wood survived. I dug it out and planted again to a pot.


It has recovered fast and is in good condition now. Bark crack is still visible, but healing.

I have fresh trifoliate orange seeds to share. It is Flying dragon variety.
If you're interested, PM me.

Cold Hardy Citrus / Re: Kumquat x Poncirus
« on: September 18, 2018, 04:40:24 AM »
Thanks for all your answers.

Mikkel, I've added descriptions to the photos.

Hardyvermont, this could also mean cross incompatibility. I'll try to check that when my Meiwa flowers. Thanks for sharing your observation.

Ilya11, I think the seeds looked more white than typical kumquat seeds, but I haven't removed the seed coats so can't be sure. Yes, I have castrated the flowers.
Nagami - Swamp lemon hybrid sounds good! I hope the cross will succeed.

Cold Hardy Citrus / Kumquat x Poncirus
« on: September 16, 2018, 08:41:36 AM »
Hi. I'd like to share my experiences on crossing kumquat with trifoliate orange.

I've heard many times that it's a really difficult cross to make, but I still wanted to try. So last year I've been making some pollinations.

Nagami kumquat x Flying dragon Poncirus
I used two different Nagami cultivars as the mother plants. Pollinated flowers set fruit easily, and seed set proved not bad. The seedlings germinated quickly, but soon some of them refused growing. Still, the rest is growing fine up till now and I hope they will stay like that. ;)


For comparison - standard Poncirus seedling on the left, Nagami x Poncirus on the right:


Reale mandarinquat x Flying dragon Poncirus
In this cross, fruit and seed set were also not bad, but most of the seedlings proved weak and generally aberrant. Some had strange, narrow leaves, and some were even monofoliate. Maybe these abnormalities are connected with the fact that Reale is triploid. Still, I think that with a bit of luck this cross is worth a try.


So to sum up, I think that crossing kumquat with the trifoliate orange is not such a bad idea. There's a good chance of getting a really cold hardy citrus with quite edible fruits.

What do you think? Have you tried making similar crosses? If yes, have you met any obstacles?

Citrus General Discussion / Re: Red lime?
« on: May 17, 2018, 03:56:21 PM »
Rangpurs are sometimes called red limes. Their fruit is actually orange like a mandarin, and sour. There's also a Rangpur hybrid called Excalibur red lime. It is said to be a local Florida variety.

Another citrus that is called red lime is the Australian blood lime. These fruits can really turn red. The plant is very characteristic in that it has small leaves and big thorns.

Cold Hardy Citrus / Re: Trifoliate seedlings - different root systems
« on: February 25, 2018, 07:25:23 AM »
Thanks for the reply, Millet, actually these are not flying dragons but anyway it seems some are zygotic. The mother plant looks like standard PT. By the way, it might be an interesting cultivar as the man who sent me the seeds called it an 'edible trifoliate'.
I have flying dragon seedlings too and there are indeed a few off-types among them, dwarfs etc. - probably they're too of zygotic origin.

That's good news, Ilya. I wonder if the presence of long taproot is a genetic trait. If yes, it could be useful in breeding frost-hardy citrus.

Cold Hardy Citrus / Trifoliate seedlings - different root systems
« on: February 24, 2018, 04:47:37 PM »
Hi. I have these trifoliate seedlings; all come from the same source and are of the same age but still differ greatly in vigour. So I guess at least some of them are zygotic.


When repotting them, I noticed that not only their vigour but also their root systems differ.  No. 1 and 2 have nice, dense roots; 3 has a poor and shallow root system; 4 and 5 have very long taproots.


Do you have similar experiences with poncirus root systems differing that much? Also, would a deep taproot increase frost hardiness?

Citrus General Discussion / Re: Hybrid Seedling Cotyledons
« on: February 17, 2018, 12:34:52 PM »
Ilya11, thanks. Triploid hybrid sounds interesting, as I understand in this case 2/3 of its genes would come from Reale and only 1/3 from trifoliata. This should give a bit better fruit (less sticky gum etc.) in comparison with a diploid cross being 50% trifoliata.

Sylvain, it's good to know the right name. Thanks for providing it.

Interesting post, Mikkel. I have similar observations - most citrus seedlings have the first two leaves paired. Poncirus and Microcitrus seedlings are different - their first few leaves are very small and don't grow in pairs.
Citrus (kumquat) x Poncirus seedlings are somewhat in between, but rather unpaired. And when there are more Citrus genes, the seedlings are more likely to develop like true citrus.

Poncirus:


Microcitrus (fingerlime):


Reale kumquat hybrid x Poncirus trifoliata. Mostly unpaired. Only one seedling has the 2 first leaves exactly paired (the one with narrow leaves, by the way it looks strange ;) ).


Reale x N1tri. The few seedlings that germinated up to now have the first two leaves paired, like true citrus. It's interesting because as your photo shows, N1tri itself has the first leaves unpaired.

Citrus General Discussion / Red Rangpur
« on: January 09, 2018, 04:39:40 AM »
I just found it on the internet - a red-fruited mutation of Rangpur lime. Called Limão cravo sanguíneo in Brazil, where it apparently comes from. Unfortunately, it seems very rare.
I imagine it makes a great potted plant. Rangpurs are one of the best citrus to grow in pots.

Citrus General Discussion / Re: Snek ́s citrus container plantation
« on: October 28, 2017, 08:28:16 AM »
Snek, I had very similar problem with my Meyer lemon. I've read somewhere it's called plant's edema (or oedema), and that it affects only plants in pots. It is said to occur when roots take the water too fast, so that leaves can't transpire it and they get damaged.
I don't know if it's really the edema, and why it occurs only on Meyers. In my case, similar as in yours, the disease didn't spread on any of my other plants. The Meyer's tree eventually lost all leaves and died.

By the way, you have really impressive plants, Snek. :D

« on: October 09, 2017, 06:10:36 AM »
Here are better pictures of one leaf, for the size.





Ynk88, your seedling has unique shaped leaves. I think it's not a pure pummelo, but some sort of pummelo hybrid. Some pummelo hybrids still have heart-shaped petioles.

This is one of my pummelo x Ponderosa lemon hybrid seedlings. The petioles aren't as big as these on your plant, but some of them overlap the leaf in a similar way.


And this one has elongated leaves, quite similar to yours, but petioles are smaller and rounded.


If yet another combination had happened, a seedling from this cross could have both overlapping petioles and elongated leaves. Then, I think it would be quite similar to yours.
I'm not saying your seedling is exactly a pummelo x Ponderosa, but who knows. ;)

@edit: changed hosting. Photobucket doesn't work properly.

I just ate a store bought Chinese Honey pummelo. They're supposed to be seedless, but well this one wasn't. I found over 120 seeds in it. If you're interested, PM me and I'll send you some seeds. They should make nice growing seedlings, possibly hybrids.
