I think the latin name is Chrysobalanus icaco.

Maybe I`m wrong, but I would say it`s maybe Plinia costata (which is native to Guyana and Suriname), because for me it looks very similar to Plinia edulis.
Unfortunately there are no pictures of Plinia costata on the internet. But as far as I know P. costata is the only species of Plinia which is native to Guyana.

Thanks for sharing! I thought that honeyberries are the first ripe fruit in Germany.

Sorry for my late reply. I did not especially ask for seeds at the first time. But I talked with them again, and asked if they would sell seeds, and they said they don`t sell seeds, they`re only a research centre.

5
I`ve spoken to IVIA, but they told me that they don`t sell scions at all, they`re only a research centre.

I`m pretty sure that this is a tindora (Coccinia grandis).

Temperate Fruit Buy, Sell, & Trade / LUBERA Voucher
« on: March 05, 2019, 01:51:32 PM »
Hello,
I`m selling plant vouchers from (the swiss company) Lubera.
I have two 100€ - vouchers. They can be bought together ore alone.
One 100€ -voucher costs 90€. If you`re going to buy both 170€.
Lubera sells all kind of fruitrees, apples, apricots, figs, pomegranates, persimons, cherries, paw paws, mulberries, peaches, quince, different citrus, jujubes, goji berries, different kiwifruits and honeyberries ... just to name a few. The best would be if you look yourself, what they all have. They send to many European countries like: Germany, France, The Netherlands, Denmark, Belgium, Sweden, Italy, Spain, Portugal and United Kingdom.

Yes I will try to convince them (in spanish) to send me scions. Let`s hope that we have more success than our friend from Ourfigs. :D
Yesterday I tried it for the first time, but it didn`t work to send them a message. But I will not give up that easily...
Yes your right, they mean the cultivar „Algerie” not the country Algeria. I somehow confused it. I even wrote two member of this forum (from Algeria and Tunisia), if they know this cultivar ;D

9
Is there a chance to ask IVIA for it?
Yes, we can contact them and ask them if they could for example send us scions.
(I could even write them in spanish, but I`m pretty sure they also understand english)

I also came across this paper but was unable to find much other information on the cultivar. Sadly even the paper itself is behind a paywall. But now I found a description of the cultivar on the website of a Spanish loquat germplasm bank. It seems to confirm its everflowering habit:

http://www.ivia.gva.es/documents/161862582/163110574/EJ081_Piera.pdf/4573833b-5f12-43e2-922a-98466ec6881b
http://www.ivia.gva.es/ca/banco-de-germoplasma-de-nispero

The cultivar is grown in Italy and Spain, so maybe someone could send us scion wood or potted plants. I will try contacting some nurseries in south tyrol and ask them if they have access to it.

I also asked for scions here: http://tropicalfruitforum.com/index.php?topic=31185

Wow, that`s great! If „Piera” is grown in Spain and Italy, it should be much easier to find it. I will search for spanish nurseries, and try to contact people form Spain and Italy. I think we will find this cultivar soon. (I`ve just noticed that ivia says that „Piera” originated in Spain, whereas the article says it is from Algeria. But I think it is the same cultivar.)

11
After long searching I found this article: https://www.researchgate.net/publication/287594421_%27Piera%27_A_new_everflowering_loquat_variety
It talks about the (algerian) Loquat variety called „Piera”, which blooms and ripens fruit throughout the whole year.
This trait could make it possible to grow Loquat in colder zones. I also think that this cultivar could cope with our winters, since it`s a pure E. japonica (not crossed with cold sensitive species like E. bengalensis).
Until now I could not find this cultivar, but if more people search for it, the chance to find it is much higher.

Cold Hardy Citrus / Re: First fruits of Citrumelo 5star x Morton cross
« on: February 24, 2019, 12:59:33 PM »
It is an open pollinated seedling of Swingle citrumelo. It is extremely hardy and although does contain some amount of internal oils, can be used for a  jus or a  curd for the tarts.
http://citrusgrowersstatic.chez.com/web/viewtopiceb1b.php
Not 100% zygotic, but after castration and cross pollination yields a  decent number of zygotic seedlings.

Very interesting, thanks. Thank you very much also for this great link!

Cold Hardy Citrus / Re: First fruits of Citrumelo 5star x Morton cross
« on: February 24, 2019, 05:15:08 AM »
Really cool! Thanks for the information and the pictures.
What exactly is the Citrumelo 5star? (Ponicirus trifoliata x ? )


15

I don't know how flowering time is regulated in the genes in loquat and what determines if a cross has the flowering time of either one of the parents or a different time altogether, but I wouldn't assume that all crosses would flower in e.g. February as that is the middle between the parents. If that were true, then creating the Spring Blossoms hybrid would not have worked in the first place.

We only want one trait from E. bengalensis, which is its spring-blooming habit. It's less hardy than E. japonica and I don't know if it produces desireable fruit. A backcross with E. japonica would ensure good edibility, better hardiness, and less unrelated E. bengalensis genes. In the offspring between the hybrid and E. japonica there would surely be winter-blooming plants, but the question is if there are still some that flower in the spring. Those would be superior plants, which are even closer to E. japonica while still keeping the valuable spring-blooming habit.

You could be right. Most of them would probably flower in between, but there could be some that flower at a different time.
This could work out. As you said, the fruits, would be even better than from the Spring Blossoms hybrid, because the resulting hybrid would have less E. bengalensis genes.

I would not cross the hybrid with other wild relatives which further decreases edibility and deviates from regular loquat. A complex hybrid with many different species and a majority of wild genes doesn't seem neccessary when a first generation hybrid with E. japonica already has the spring-blooming trait. I'd rather cross a northern E. japonica cultivar with E. fragrans, E. elliptica or E. petiolata if I have access to those.

I have to agree totally. Yes, crossing a nothern E. japonica cultivar with one of the spring blooming cold hardier species, seems to be a far better idea.

I also found sources that state that E. bengalensis flowers in the winter, but according to the paper, they chose E. bengalensis as a hybrid partner for E. japonica particulary because it flowers in the spring. I don't know why e.g. Flora of China states that they flower in the winter... ???

The information about flowering/fruiting of different Eriobotrya species is very confusing. I thought for example that E. japonica always flowers in winter, but Flora of China says that E. japonica flowers in June (and fruits Jul-Aug). I don`t know exactly why, but it seems that the same species in China has a completely other flowering (and fruiting) time in Europe or America. Additonally there comes a difference in flowering time, depending on the (hardiness) zone. The same species probably flowers earlier in the warmer areas of its range. But I don`t think that the zone difference is the only reason for the difference in flowering (,fruiting) time. Therefore it could be, or more likely has to be that other Eriobotrya species planted here, also flower at a different time than Flora of China says.

I also think it`s Mangifera quadrifida. On this website: http://www.kujie2.com/wordless-wednesday/buah-asam-kumbang.html, M. quadrifida is called Buah Asam (Kumbang). Here some information about M. quadrifida http://tropical.theferns.info/viewtropical.php?id=Mangifera+quadrifida, it should have a prune-like smell. Or it could be some rare Mangifera species, of wich there are no pictures or information on the internet. I hope I could help at least a bit.

@Patanax
Yes, maybe they would flower later if it would be to cold in march. I haven`t thought about this. But maybe if there would be a warm and sunny period for a few weeks in march, they would think: „Oh, the winter is over, the cold temperatures are gone”, and would start flowering. These flowers would then get completely destroyed, when the warmer weeks would be over, and it would get cold again.
Yes, the hardiness would be the next difficulty. This hybrid is maybe not hardy enough. (Since it`s probably a cross of a subtropical/southern group cultivar with E. bengalensis). Backcrossing with E. japonica is maybe not such a good idea, because all E. japonica flower in winter. So the cross would probably flower in between the two parents, therefore in February or so. (The flowering time would be developed in the false direction). On the opposite a backcross with E. fragrans or E. elliptica would be a good idea. (By the way, what do you mean with: „It would also be interesting to try a similar cross with one of the cold-hardier spring-blooming species”? Do you mean to cross E. japonica with one of the cold hardy species, or do you mean to cross the Spring Blossoms hybrid (japonica x bengalensis) with one of the cold hardy species?)
And one last question, do you know how he was able to accomplish that his hybrid flowers in march? (Since E. bengalensis flowers Nov-Feb, and E. japonica normally flowers in late autumn or winter). Did he selected the hybrids for late blooming?

@mikkel thank you for your information, E. fulvicoma (zone 10) is even less hardier then E. bengalensis (zone 9), but the late flowering is definitely a trade, that makes this species very attractive for crossing with other species.

So I wrote the corresponding author of the paper "Identification of interspecific hybrids between loquat (E. japonica) and bengal loquat (E. bengalensis)" and asked him about the progress of the project. While he is already working in another area, he sent me a link to a news article.

Original: https://sichuan.scol.com.cn/yaxw/201806/56299857.html
Google Translate: https://translate.google.at/translate?sl=zh-CN&tl=en&u=https%3A%2F%2Fsichuan.scol.com.cn%2Fyaxw%2F201806%2F56299857.html

Apparently the hybrid trees mentioned in the paper have already flowered and fruited twice and produced tasty loquats. From what I've understood via Google/Bing Translate, they flower in March (the text also mentions April?) and produce fruit in June. Their current temporary cultivar name is "Spring Blossoms" loquat ('春花'枇杷) and the trees are located at the scientific research park of Sichuan Agricultural University. The team is currently trying to graft them on regular loquat cultivars. Can anybody who speaks Chinese confirm (regarding April)?

So I guess there are spring-blooming loquats now :D

Wow, that sounds great! March is still to early (ad least in zone 7a), but it`s a huge step in the right direction. Thank you very much for informing you about the progress of the project.

I think Grapebush is right. It`s a Pouteria caimito/Abiu. But I would not say it looks strange or overripe. It`s just an green/unripe abiu.
Abiu can vary a lot in fruit shape. Not al abius are round.

Hi,
I can not see any picture. For a identification a picture would be helpful.
Probably you just forgot to add it.
Best Regards,

Hello,
It could be Ampelocissus acapulcensis, A. erdvendbergiana, A. erdwendbergii or A. mesoamericana. All of these species occur in Mexico.

« on: January 17, 2019, 01:19:31 PM »
Thanks for your information, the only problem with Opuntia species are the nasty glochids, but the fruits are certainly good.
Interesting to know that the length and intensity of the summer can have an impact on the flavor of the fruit.

Of course I would keep the good/better tasting ones instead of the barely edible ones. But if you want to find as many good tasting cactus species as possible, you have to try all and decide. Edible simply means not poisonous. It`s important to know that all true cactus species are edible (=safe to eat), if you going to search for good tasting species.

Thanks for your information. I`ve done a lot of research myself and found out that all true cactus species are edible, of course there are some more suited for eating then others. But all are edible. So if you want to know wich cactus species produce edible fruit in your cold climate, all you have to know is which species are hardy in your zone.
