Cold Hardy Citrus / Re: How to store seeds

Walt, one obvious doesn't want to use the oily Bag Balm itself, it's just that it's active ingredient is the same as the fungicide used by commercial seed companies.

I've had success with thoroughly cleaning the seeds with an admixture of chlorine (Sodium hypochlorite) at 5 times the concentration used to sanitize drinking water. Gently scrubbing with a scouring pad until all gelatinous tissue is removed is important to prevent mold. After the seeds are completely surface cleaned, I then surface dry them on a bakery tray until they pour freely without any seeds clinging to each other. It's important that the seed coats are dry, but that the actual seed interiors aren't descicated. Over drying the seeds is lethal.
At this point the seeds are scooped into Ziplock type bags, with any excess air being squeezed out while sealing the bags. The seeds are then stored at near 32°F until being sown. Stratification isn't harmful, but also not necessary.
It's a good practice to inspect the bags for mold on a monthly basis. Minor mold be stopped by an appropriate fungicide application.
Commercial seed treatment makes use of 8-hydroxyquinoline fungicide, which is very effective for mold prevention, but may not be readily available, nor suitable for hobbyist use. It's used in the winemaking industry to eliminate wild yeasts, and in the dairy industry in a product called Bag Balm. Once again, it may not be advisable for hobbyist use.

In my experience, when the seeds begin to harden a percentage of them will germinate. I've sown seeds that were becoming viable and varying percentages germinated. I found that marginally mature seeds don't store well and by sowing them directly after extraction the odds improved.
Excessively wet soil media contributed to failure on several occasions.

Sorry, "9 fruits" in English. This tree fruits in clusters of fruit. I prepared the caption for a German speaking friend.

I'd leave it as is temporarily. When a vigorous shoot emerges below the damaged area, but above the graft union I'd allow it to gradually overtake the damaged branch. When the replacement is sufficiently mature and lignified, the damaged section can be removed.

Not a pumpkin, but it's definitely ribbed.

Wow, that's great! Conestoga 058 is something incredible!
My hope is that having Ruby blood orange ancestry, 058 may exhibit fruit coloration under cool Autumn nights. Unfortunately, this selection hasn't bloomed to this point.

Recent photos of a Dragon Lime fruit, Meyer lemon fruits containing hybrid seeds of several crosses and Autumn coloration of Conestoga 058 foliage. This is the most brilliant foliage color of my plants.

The sibling to the better tasting specimen clearly appears to be a Poncirus/Citrus hybrid. Being siblings, both trees should contain a mixture of Citrus and Poncirus of undetermined proportions. It's a very interesting find and may be useful for further cold hardy breeding potential.
The fruit also show good coloration.

Congratulations on your discovery.

A number of field grown Starburst and Cocktail seedlings are being potted in preparation for Winter. Transplantation may be a considerable shock. These seeds were sown indoors in Winter 2023/2024..

Thank you for the inputs, guys.

Kumin,
The fruit of your 026 pictures is very similar. But the juice of yours is paler. I guess the very pulpy juice of this local PT is the result of the very hot and dry summer we had this year so it may not be a standard trait. Maybe next year I will know better.

Jibro,
Those two are also quite close. I have no idea what this local plant is. I think its fruit is pretty good for a pure Poncirus, but if it's a hybrid, well, that should be a higher standard. I wouldn't like to eat even half a fruit, that's for sure. After my second review last week, when I consumed a little more of it than the first time, I felt a bit sick. But apart from that, I found nothing in this fruit that would urge me to eat it. Its juice is quite agreeable though, especially for a Poncirus, if that's what it is.
I should have been clearer in the description, the white ramekin has the actual juice, the glass container has the diluted beverage at 20 percent juice content.

I have experience with F² Poncirus hybrids. F² zygotic hybrids are generally more variable in form than F¹ hybrids. Some are monofoliate and approach Citrus in appearance, others are nearly indistinguishable from Poncirus itself. At least one of my F² hybrid selections appears to be a Poncirus tree, yet when it's pollen is applied to Meyer lemon flowers quite a few of the seedlings are predominantly monofoliate indicating it's Poncirus X Citrus hybrid status.
Photos of 2 such selections that are cold hardy to -12°F (-24,5°C). These exhibit strong Poncirus characteristics, yet 026 produces many monofoliate seedlings when it's pollen is applied to zygotic Citrus flowers.
My recollection from the past is that both of these make acceptable beverages when diluted 20/80 with water and sweetened. To the best of my recollection 026 is slightly better in flavor.



Photos of Conestoga 026 fruits and juice which appear quite similar to your fruit. I can only speculate that there may be similar genetics involved.

The presence of empty seed coats might indicate it's a Poncirus hybrid.

5 or 6 years from seed. The first blooms developed at 3 years old.

I hope to make a side by side comparison between Poncirus Plus and the Conestoga selections in the next few weeks.

In regards to Cocktail I only have seedlings, no fruiting trees. I need to examine them again, I was under the impression that there was some variation.

I have Thomasville kumquats, but need to find a zygotic Conestoga selection to make it happen.

There is indeed a general decrease. Vigorous shoots tend to be slower to exhibit the decrease. Poncirus also has fewer thorns on the higher fruiting branches, but the transition is not as well defined.
This selection, being in a group of Segentranges, has far fewer and shorter spines than the majority of its siblings do.
Not having fruited to this point, it reminds to be seen if the selection has any additional characteristics of significance to offer.

Conestoga 062 is a selection with reduced thorniness in the upper ends of flushes.

Conestoga Segentrange 067 as well as Bishop and 1279 Citrandarin are prone to have these types of variable flushes.

A pdf relating to Thornlessness in Poncirus trifoliata. Of particular interest is the presence of zygotic seedlings in multiple selections of thornless trifoliate orange. The nearly thornless Conestoga 121 selection, while being a Segentrange rather than a pure Poncirus, might potentially also be zygotic?
121 has neither flowered, nor fruited to this point. Hopefully, it will do so within the next 2 years.

Bishop fruits are developing nicely, but clearly show that blooming on new growth delays maturity in Autumn.


In contrast, 004 Conestoga blooms on overwintering flower buds and has at least a month lead over Bishop in regards to time of ripening.
Blooming on the previous seasons growth may be a factor in having the fruit partially hidden by Summer foliage enveloping the early fruit set.

Looks like they are starting to ripen up there.
Wahl, once the fruits attain adequate maturity cool night temperatures will cause the rind to color. I'm not certain how strongly rind coloration is correlated with flesh ripening, especially the increase of sugars. The hardiest selections abscise and drop when ripe. This is likely inherited from the trifoliate parentage. 5* Citrumelo, in contrast retains its fruit until much later.
I suspect there may be some correlation between early fruit abscission and deciduousness.
