Tropical Fruit Buy, Sell & Trade / Avocado budwood for sale (Europe)
« on: June 23, 2019, 06:38:03 AM »
Hello,
I am going to cut some twigs from my avocado trees, if someone interested.
Cultivars are:
Fuerte, Bacon, Reed, Hass
6€/ cutting
shipping usually costs cca 2€.

Looks like in Italy, they distinguish  different kinds of lemons from the same cultivar.
Femminello comune is a greatly reflowering cultivar with high setting aptitude; it has five annual blossomings to which five different names of fructifications correspond.
The most important blossoming, from a qualitative point of view, is the first, which produces fruit that ripen from October to March. They are the so-called ‘’winter lemons’, with a more or less rough epicarp, a high sourness and a variable number of pips. The earliest fruit of this first blossoming, which ripen between September and October, are called Primofiore; they are highly valued on the market. Then, there are the so-called ‘‘maiolini’, ‘’biancucci’ or ‘’bianchetti’, which are light yellow, with a slightly rough epicarp, few pips and a lower level of sourness. Very often they bear fruit in bunches; the ripening is between April and May. The famous ‘verdelli’, ripen in the summer of the following year, are rather cheap. The verdelli, that usually grow in bunches, have a smoother epicarp, a low sourness and almost no pips (technically, they say that the pips are aborted). Then, there are the so-called ‘‘bastards’, which ripen in after more or less a year and have a smooth epicarp and a deep yellow colour. Lastly, we have to remember the ‘‘marzani’, usually picked together with the winter lemons. They are never numerous, more or less of a round shape, and they have a rough epicarp, a long and flat umbo, a certain number of pips and a high sourness.

If the trees ever become available... But no, I'm not willing to "pay a premium price" for a seedless lemon. Joe Real just sent me budwood for a seedless lemon.

http://www.wonderful.com/press/wonderful-seedless-lemons-announced.html


Uf....That announcement sounds like some kind of sect.  Clear example of company, where half of the price is "story and brand".
Something like bottle of city water for 100$, because it is unique, carefully packed, our staff do it with love,  America’s No. 1 and 100% organic.

Cold Hardy Citrus / Re: Ichang lemon Sebastien
« on: June 05, 2019, 01:32:19 AM »
It is possible that 153 and CRC 1215 are identical!
From Eisenhut list:
153 Citrus   Ichang Lemon   Ichang Lemon   (C. ichangensis x C. maxima) / C.R.C. 1215; bedornt - Papeda-Hybride.

So far I see following cultivars in Czech nurseries:

Ichang lemon CRC 1215( shangouyan)
originaly from https://citrusvariety.ucr.edu/citrus/CRC1215.html
Ichang lemon IVIA
originaly from L'Institut Valencià d'Investigacions Agràries (IVIA)
It is Citrus ichangensis Swing. IVIA - 235 or Citrus ichangiensis Swing. IVIA - 358
Ichang lemon wilsonii
from USSR
Ichang lemon 153
Ichang lemon "Sebastien"
Selection from France,

 on czech forum Zdenek Cernoch described only Ichang lemon CRC 1215( shangouyan) as really edible.

Cold Hardy Citrus / Re: yuzu hybrid
« on: June 02, 2019, 01:18:15 AM »

I did not know a chance to taste the leaves of citrus medica, citron to see whether or not it fit  y cookling needs. I would appreciate so much if you can describe the taste of a citron leaf compared to a lemon leaf.


Ok, I will chew some citron and lemon leaves today to compare and let you know.

Cold Hardy Citrus / Re: yuzu hybrid
« on: June 01, 2019, 03:37:50 PM »
Is sudachi seedless or less seeded? Is it as cold hardy as yuzu? Does its leaves taste and smell similar to yuzu?


There are several sudachi cultivars, seeded or seedless.

Btw. why you are looking for lemon (citrus limon) leaves? In Europe, in subtropical areas, citrus medica (Cedro or Citron) leaves  are used not lemon.

For example for famous Kitron (citron) liquor.

Cold Hardy Citrus / Re: Interesting japan citruses.
« on: May 31, 2019, 07:53:19 AM »
If the translator is correct they pollinated tetraploid Honda group  Sudachi with diploid Yamane Yuzu pollen.
Then  rised the embryo in vitro. Then checked the chromosomes number and triplods where selected, In 1997 they made selections of seedlings to choose something with taste between yuzu and sudachi. In 2001 they got new fruits, but trees were very high and with weak flowering, so they make second generation of seedlings and another sellection. In 2023-14 they selected tree with medium grow and heavy flowering.  Cultivar was registered in 2015.

« on: May 31, 2019, 04:53:18 AM »
I  just came across the info about new interesting acid citrus triploid, cross  of yuzu and sudachi.
It is called Awasuzuka 阿波すず香.



Yuzu, Awasuzuka, Seedless Sudachi (tane nashi sudachi 種なしすだち)

Cold Hardy Citrus / Re: yuzu hybrid
« on: May 31, 2019, 04:30:59 AM »

 I have a little idiot question about yuzu. I knew that yuzu was actually a hybrid citrus; however, it is very seedy and less juicy. I just wonder whether or not there exists a yuzu hybrid which offer a better quality than yuzu lemon.



There is a cultivar called nishiki tada (yuzu seedless), but those who grow it, say that the juice is less tasty then standard yuzu.

Citrus General Discussion / Re: Siamese Sweet Pomelo
« on: May 31, 2019, 03:07:10 AM »
Few years ago i also managed to get a corsican citron, which should be acidless, with the same idea in mind, to attempt to cross it with some other citrus (nagami kumquat was my original idea) in order to attempt to breed an interesting citrus.
I guess corsican citron is not acidless, but has a thick sweet albedo, giving an impression of fruit being sweet.


Corsican pulp tastes like sweet peas.



There was no ripe fruit yet.



I guess that you have cultivar spread from Czech Republic. Many years ago Mr. Broza brought it from Menton –  Edouard Mazzola collection.
At that time it was marked just pamplemousse Siamensis. Several years later Mr. Mazzola changed table with description to Kao Phuang.

Citrus General Discussion / Re: House in greenhouse. Citrus garden
« on: May 31, 2019, 01:00:24 AM »
zero radon??
At high altitude greenhouse temperature will not be a problem


Radon from soil is dangerous, when concentrated.
In my country there are companies who provide measurement of radon level in building plot, when level is low, regular ventilation  is enough. When high, special isulation of base is needed when you build a house. When you cover house with greenhouse, you will encrease radon concentration.
Greenhouse temperature can easy reach 50°C durig summer, high greenhouse can help, but water will condense on house walls and windows.

House inside the greenhouse. The heat loss of the house to heat the greenhouse. In the greenhouse it is now possible to grow a citrus garden


There are some problems like Radon, you have to choose area with zero radon gas concentration, another is  high air humidity etc.
Heat loss is not enough to keep temperature above zero in big greenhouse.

Citrus General Discussion / Re: Micropropagation
« on: May 23, 2019, 02:59:22 AM »
I am not sure what you are up to with micropropagation, but I see no sense to use it, except to clean the budwood.
You have all answers to your questions on web. It is not an easy technique.
So, mature  material is not easy to regenerate via in vitro, juvenile is doing better, but who will multiple juvenile plants?
Very good info:

Yuzu is common in EU nurseries.
Also Kabosu appeared in nurseries in France, Italy and Czech Republic some times ago, but there are questions about budwood source and if it is clean of ctv.

I can't tell for any nursery in EU but i know for a fact that our phytosanitary service routinely inspect citrus nurseries for CTV, so if someone has it in catalogue, they should have been tested.

I do not think so.

BTW, speaking of seeds, does anyone knows if in europe there's any kind of seedless yuzu?

In some private collections in France and Belgium, but there is a problem with CTV.

I did not eat yuko, but I heard that it is just sour water.

Sylvain had a first harvest of his Yuko seedling in 2017, it seems that the fruit was early,quite  sweet but odor was faint, nothing to do with Yuzu.

French forum

Google translation



The pictures fit to Tanaka description of citrus yuko except the taste.

Tanaka wrote: "YUZU hybrid character, fr size good sized Satsuma, shape resembles Kunembo- rough, orange-yellow, Calyx provides 1g disk ring, rind 5.0 mm, ht 5.0, wid 6.3 cm, pulp poor taste, apex rounded, base pointed, 8 seeds, seeds green polyembryonic"

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

22
But as far as I know sudachi and yuko are not worth to grow for fruit, only as curiosity.

Hey Radoslav, care to elaborate? Are they insipid/wortless for lack of juice, and/or unpalatable?


Sudachi has the smallest fruit of all basic japan sour fruits

I did not eat yuko, but I heard that it is just sour water.

I think that some nurseries propagate citrumelo rootstocks by rooting the cuttings.

The Yuko plant I ordered is coming from the UK. The Yuzu and Sudachi is imported to Europe as fruit, not plants.
