Which Poncirus did you use as pollen donor? Mainz?

This is a description of a Hiyu on the japanese genebank seems it hasn`t any specific traits..

Cold Hardy Citrus / Re: Sacaton Citrumelo F2 seedlings
« on: November 30, 2019, 04:44:42 PM »
In fact I remember Yuma fruits from Eisenhut as better ones. I have about 10 fruits on a plant they are still green. I am curious if they are nucellar.
Florian you seedlings look like my seedlings which have Ichang Papeda as pollen parent. On my plants I know pollination for sure. Do you have an idea what yours came from?

On this table from Ilyas post Yuma and Sacaton have both some zygotic seeds

From observation over the last years I won`t expect growth rate like you both. 1 year seedlings are no more then 20cm in height at the end of the year. No matter if irrigated, fertilized or not. I observe a strange growth pattern here  in my garden. First flush is often stopped by the cold again, in June is another flush. In late August plants start to grow again this is the strongest flush but most of this growth will freeze in winter as it isn`t really hardened when it gets cold.
I expect it is due to our climate here. Not much heat in summer.
I doubt such 1 year seedlings will survive a strong winter. 2 year old plants may be better suited. On the other hand winter has been very mild over the last years. They might survive but probably less cold selection wil take place...

Kumin, How old were your plants when you planted them out? They seem to be very large for 1 year old plants?

It`s a pity.  I know some sellers in the US with quite reasonable prices. But it isn`t allowed  to import seeds anymore. As long as you aren`t a scientific researcher it is not possible to obtain an import permit.
I wish I had done it before ...

Great! Send you an email.

It was my impression too (but it is just my impression) that when I did cross pollination many seedlings were zygotic. Especially when I pollinate with Ichang Papeda. For sure the majority were monoembryonic.
Now I plan to do a large scale winter test similar to what Kumin did. So I need a large amount of seeds. I found only INRA as a supplier in Europe with a very restricted selection of varieties. Today I got an answer that even less varieties than in the catalogue are available.
Sacaton and Yuma are not available.
Are there other seed supplier in the EU? I thought spanish nurseries might have seeds. But couldn`t find any so far.

for sure it depends on different factors and these numbers are not fixed. I see it it only as an advice what is most likely the best.
US852 would be a good option but it isn`t available in Europe in suitable amounts.
This is what I can choose from

I will go for Sacaton and Yuma if available.

Nobody has seen these tables?
I intend to make a seed trial  and would like to know which variety has the greatest chance of giving zygotic seedlings.

Eisenhut in Switzerland has it.
Some fruit pictures:

I know there several posts here and on other forums about average percentage of zygotic/nucellar offspring in different Poncirus hybrids. But I can`t find it now.
Anyone can help?

Almost half the tree's that i buy are grown in pure charcoal dust.....and i'm not going to argue about it i know what i see.
Just to be sure. I hope you didn`t misunderstood my post. I am interested in it and I want to know about it.
My post was a reply toSeaWalnut.

Also ,to grow plants in charcoal only doesnt seem to be a good idea because ...

but they do, as @sunny has published it. Shouldn't the question be how they do it?

Citrus Buy, Sell, & Trade / Looking For Poncirus Fruits ( EU only )
« on: October 21, 2019, 02:23:58 AM »
This might be a little late but I am interested in comparing different Poncirus fruits.
Anyone still has some and can send me 1 or 2?

I am inside EU.

You said you used a lot wich is thats why your plants didnt grow- your fault.
That`s what I intended to say  I tested it with an higher percentage and it failed so it might be helpful for others to know. But it is not to show that it is wrong at all. It`s not a blame game. :)
It is fine that others say what percentage is right, my intention was to test "what is wrong" or if there is another "right".
I am interested in Terra Preta but I am open to the idea that it might not work for everything as well. So I test it by myself.

Before charcoal can be used it must soak in nutrients for a longer time. If not it will be a detriment to any plant.

I saw a series of tests on the web, can`t find it now.

it is more the ash that provides the nutrients. Charcoal is a huge sponge and will absorb anything until it is loaded.
Growing plants with fresh charcoal will not benefit the plants.

In every case you need to "load" the charcoal with nutritions. If not it will reduce nutritions and harm any plant.
I tested some potted Citrus with a Terra Preta mix with very high percentage of charcoal. Plants stopped to grow. Even at the end of the season no new leave showed up.
There are several plants which don`t like to grow in Terra Preta. If Citrus is one of them I can`t tell.
More probably you need to find the right percentage of charcoal by testing.
