The Tropical Fruit Forum

Do they really ban grafting citrus trees? Sounds unreal to me.
And yes, technically you can use cleft grafting whole year.

As it was mentioned somewhere on this forum before, irradiation by gamma-rays is common practice in breeding of news fruit or vegetable  to trigger mutations since 50´ .
For example some citruses:
"Star Ruby" - seeds from "Hudson Red" grapefruit seedling irradiated at the Texas A & I Citrus Center, Weslaco, in 1959.
"Murcott seedless" -obtained by bud irradiation from the self-compatible not parthenocarpic ‘Murcott’ mandarin.
Seedless strains of "Foster" grapefruit through y-irradiation of buds etc.

Durian Lover, I have to support your statement - both parts.
And yes, my cousin is married with one Dutchman and when it comes to average height,  Holland is the number one in Europe most likely - maybe, because they do not have hills, so  they have to be so tall to have a proper view for long distance

I do not know the name of variety, it was bought in supermarket in Jakarta.
All family members said  - never again. 

Yesterday, I ate the red fleshed pitahaya for the first time, I got the fruit from Indonesia, but I have to say, that it was the same experience like with the white fleshed one, both taste to me more like vegetable than fruit, something like radish, really  not worth to grow as a fruit. But may be it is because of me, who grow up in Middle Europe,  eating  tens of different varieties of plum, apple, apricot, peaches, pear  etc. 

If it is subtropical, could be a good rootstock for more tropical artocarpus varieties, because they do not like my greenhouse conditions. I would like to buy some seeds to test it.

Yes it is possible, the text of confirmation email was partly in slovak language and it says: "Prosím potvrďte objednávku predplatného" - literally it means some kind of paid newsletter.
But possibly it is just wrong automatic translation.

I do not see any "I want seeds!" box. Just box "subscirbe" some newsletter.

Top-working on citrus tree is a common practice.
If you graft different variety on different branches, you will get so called cocktail tree.

Some pictures to the discussion.
