Cold Hardy Citrus / C. depressa Shikuwasa Cold Hardiness
« on: June 22, 2022, 04:54:25 PM »
Hi,

I have some shikuwasa rooted cuttings, and soon some seeds that I want to use as rootstock. Does anyone have experience how cold hardy it is?

Citrus General Discussion / Re: 4-leaved yuzu Seedling

Yuzu has a distinct scent in the leaves I am curious if a hybrid would retain the nice smelling leaves, but yes this definitely looks like a hybrid congrats lol

I'm trying to cross my Yuzu with trifoliate, really cool that you randomly got a hybrid from a fruit you purchased (assuming this came from the Yuzu fruit you mentioned looking at your post history).

It originated from a fruit imported from Japan. What are the odds! I will be keeping my eye on this one  ;D

It's probably a hybrid if it keeps on putting out trifoliate leaves

That would be my first guess as well!

can we see more of the plant? what do the leaves smell like when you scratch them?



Not sure about the smell, similar to other seedlings I guess?
Apart from the leaves the size and growth is very similar to my other yuzu seedlings.

Citrus General Discussion / 4-leaved yuzu Seedling

Hi,

One of my yuzu seedlings consistently makes four leaflets. Has anyone seen this before? Is it common?
Could it be a hybrid?

Citrus General Discussion / Re: Citrus juvenility and internode count
« on: June 12, 2022, 05:01:14 AM »
I have a Yuzu seedling that just started to flower from seed, last season. It has 2 main stems, so would be about 2 metres tall and slightly bushy with side branches.
Haven't counted the nodes, but would be the same for any 2 m tall citrus, not overly vigorous with normal bud spacing.
The plant is in a pot, and has been on the back burner. It is well over 10 years old, but has been neglected over the years, until now it started flowering.
As I recall Yuzu is not one of the faster types to fruit from seed.
Anything that can be done to speed up the growth rate to achieve node count will be helpful., i.e. extending the growing season with protection or heat or repotting as required.

Very interesting! I will be trying to speed up the growth of my seedlings

I am becoming skeptical of the node count explanation as I have a few rootstocks that fruited after the scion died.

Generally I would agree, some plants seem to flower or fruit despite the node count theory.
However in the case of a formerly budded rootstock, was node count achieved by the whole grafted plant,
and flowering maturity transferred to the rootstock ??
Another possibility is flowering hormones from the mature grafted scion influencing the rootstock.

Normally after achieving the necessary node count, all new growth will be adult and can flower. I would agree with you that the rootstock is likely a cutting.

There are some studies were a gmo rootstock was able to induce flowering in a juvenile scion, so it could surely be possible, although the likelyhood of it being a mature cutting would make more sense.


My four winds cuban shaddock's scion died and it flowered and produced fruit.  the rootstock was a rooted cutting.

I hadn't consideres that the rootstocj itself might be a cutting.  Is that common?  I thought most citrus are hard to root.

There are some good protocols for rooting citrus out there, this one for example:

Any chance you would be willing to sell a plant or send some cuttings?

Unfortunately some fungus infected the seeds. Perhaps I can get some fruits next year and try again

Next time send them to me I can help you germinate any kind of seed and send them back.

Thank you! Will keep that in mind!

Citrus General Discussion / Citrus juvenility and internode count
« on: June 07, 2022, 02:51:34 PM »
Hi!

I am quite interested in citrus juvenility. There are some studies that suggest after x amount of plant internodes, the seedling will become adult. One study observed flowering earliest at around the 50th internode up until 120ish internodes. In my opinion, genetics clearly play a role, especially considering precociousity.

Does any one of you have experience with the number of internodes required for flowering? I am especially interested in yuzu, and when to expect flowering in my seedlings  ;D

Hi!

I got my hands earlier on some Citrus haruka fruits from France. I really enjoyed the fruits.
Unfortunately, I was not able to germinate the seeds. Does anyone know where within Europe I can get some budwood or a tree?

Thanks in advance!

« on: April 07, 2022, 11:50:10 AM »
There is also a study where shikuwasa was used as a rootstock for inducing early flowering in hybrids.

https://www.sciencedirect.com/science/article/abs/pii/S0304423808000770?via%3Dihub

It is probably a very vigorous variety. I hope to have some seeds this year, and see for myself!

Hi!

I have some yuzu, poncirus rootstock and soon some kabosu seeds for trade.

I would be interested in some budwood or seeds in return. I am mainly interested in Japanese varieties but feel free to send me a message with whatever you have  ;D

I know a grower that sells excellent poncirus plants, however; they are located in the Netherlands. I can give you the contact information if you are interested, although their site is in Dutch and I am not sure if they are willing to ship.

Cold Hardy Citrus / Re: Sansho Pepper
« on: June 20, 2019, 05:50:43 AM »
It said Sansho is in the citrus family.  Do you know its genus and species?
Near the end, it said it is a good to sprinkle it on vanilla ice cream.  I was reminded that some like chiltipine powder on vanilla ice cream.  Chiltipine is the wild ancestor of domestic chili peppers and is extremely hot, but also with a strong pepper flavor aside from the hot flavor.

I had no idea that it is used on ice cream, I have to try that  ;D


You need both the male and female plants if you want to get any berries to form, so you'd probably need to grow several seedlings together. (Although the leaves can also be used)

I have a Sansho bonsai, and I was hoping to have some fruit this year, but I guess I will have to find another one

Citrus Buy, Sell, & Trade / Yuzu (EU)
« on: June 20, 2019, 04:33:58 AM »
Last year I got my hands on some Yuzu fruit imported from Japan. I sow the seeds and now I have way too many seedlings. I have many available, I would love to trade for some other citrus seedlings or budwood. I would also be willing to ship them out for free as long as you cover the shipping fees.

Hi,

I am looking to practice some grafting, so I am looking for some budwood. I mainly collect Japanese citrus varieties but I am open for anything  :D . I am based in Europe

kabosu, bushiyukan, naoshichi.


But sometimes the small size is advantage.
I really like my hanayuzu tree, I am using it as substitute for lemon and small fruit has juice just for one cup of tea so it perfectly fits. No need to store juice or cutted fruit.


Hanayuzu, Hong yuzu, Shishi yuzu 花ユズ、本柚子、獅子柚子.j

Thank you for your clarification. Those pictures really show a lot!

Edit: I've updated the post

Citrus General Discussion / Re: Micropropagation
« on: May 23, 2019, 02:31:18 AM »
I think micropropagation could be really interesting, especially for citrus. However, it does require extensive equipment. Furthermore, you can't really determine if your propagated plants have a juvenile phase or not, which means you should base your method on work that was previously done (or be patient).

I was also wondering if it could be useful to graft citrus seedlings? I have some experience with in vitro grafting of tomato, and the protocol is very straightforward (if you have the right equipment). Would grafting citrus seedlings give the same benefits as grafting rootstock with scion? Any experiences?

Citrus General Discussion / Re: Micropropagation
« on: May 20, 2019, 02:00:28 PM »
This is a very interesting question, I have thought about this myself. During micropropagation, the cells undergo dedifferentation. It could be that therefore the plant could have a juvenile stage again.

Citrus General Discussion / How to promote new growth on Scion?
« on: May 16, 2019, 03:30:11 AM »
Earlier this year I bought some interesting Citrus varieties. They have started to grow new branches, but I've noticed that 4 out of 5 plants all started new growth on the rootstock part of the plant. Is there any way to promote growth on the scion (other than just removing the new growth on the rootstock part)?
The rootstock is P. trifoliata and the scion is C. sphaerocarpa (kabosu)
