Cactus fruits

Recommended Posts

I thought we could share pictures of cactus fruits, not only trichocereus to compare them and talk about it. Here we can also talk about taste of fruit if various genera. Seeing fruits of different genre and species, is also of taxonomical interest.

for example in Echinocereus (echino means spiny) both the bud and base of the flower as well as the fruit are spiny

anyways

harissia jusperti in a very small pot, they seem quite easy to flower and fruit for me. I have no idea whether they self-polinate or cross with something else, but I tend to believe the former.

Mammilaria prolifera, they're prized also for the show off of their fruits, since there's little else to show off apart from a nice impressive tuft.

let me be a bit sentimental here. this was sent to me by the awesome dude woof woof... from a place far- far away of this world... so for me, it will be always be woofwoof's mammi prolifera, which was seed grown...

peace

PS: mammilaria identification thread here

http://www.shaman-australis.com/forum/index.php?showtopic=41160&hl=mammilaria

seems to have some of my own mammilarias

PS2: some times , in mammilaria of cultivation especially, specimen can rot from the excess of fruits... so it is regularely suggested for mammilaria growers to remove the fruits as much as they can - not for this species though...

ps3: fruit seems more roundish, or eggplant shaped than usual

Had two fruits recently on these two pilosocereus. Very cool looking!

Awesome! I had a Pilo azureus flower for me a couple years in a row, but only got one. I assume you have more than a single plant?

Yeah mate, have 6 different pilosocereus. Those two were crossed with each other.

IME most Pilosocereus are self fertile, although that said the fruit & the seeds appear to be bigger when out crossed with a different clone.

Zelly its not boring at all... I am loving it and I am sure others too..

got a question though: how are you sure the transgenic fruits were polinated by the males you indicate? you mark them like with your tricho hybrids ? isolate them? or so you simply keep a close eye to all and figure out what pollinated what by compatibilities and by what is flowering each time?

interesting you mention Oroya borchersii x matucana madisoniorum cross as I got both plants at flowering size but they're at different locations.. well I think mine is Oroya peruviana. .. Should propably get them together to mate.

well generally speaking I'm limited to flowers that happen to be open at the same time, regardless of where they might be located in my yard, garden or green house.

I hand pollinate via the tweezer method, grabbing a bunch of pollen laden anthers from the male and walking from front yard to back yard or wherever & jamming them into the pistil of the female.

when the second flower on the borzicactus x matucana hybrid opened, the only plants in my garden that were flowering were an A fissuratus and an A retusus, so thats what i used in an attempt to pollinate the second flower. I should know in a few more days if that fruit takes or not.

In this and all previous cases, did an insect or flying critter come along & pollinate the flower(s) when I wasnt looking? who the hell knows? All I can go on is my own actions, and given the uniqueness of each cross, its not too terribly difficult to remember what was crossed with what.

For me its not a question of whats supposedly compatible or not, all I need is two flowers of different species to make an attempt.

Zelly

Be most interested in what the selenicereus ptranthus tasted like.

I have an Echinocereus pentalophus clone which, provided the fruit is picked when fully ripe, has a Banana like flavor. Plant is not self fertile which is a bit of a pain.

Cheers

Sorry mate, I didnt sample it. The flowers dont seem to be self fertile & I was so stoked to see a fruit I processed it for seeds.

The second flower fruited, although it looks to be incredibly small....

Its actually neither. They are not self fertile and you can pollinate them with trichs, echinopsis, gymnocalyciums, etc. and they will take it as a cue to set apomict seed, seed-form clones of the mother. Apparently only one Harrisia jusbertii exists and all specimens are clones.

To date its the only columnar I've got to flower up here. I pollinated it with Echinopsis chamaecereus and it set fruit, but the unripe fruit was ripped off by an unexpected sand storm, lol

A question EG may be able to answer: If a trich is pollinated with H. jusbertii pollen will the Trich set apomict seed?

A cross between Eriocereus jusbertii / Harrisia Jusbertii and Echinopsis as mother results in phaeno typical Eriocereus hybrids. The reverse cross should produce relatively normal Trichocereus hybrids. It´s almost certain that Eriocereus jusbertii is a hybrid that was created in a collection or nursery, which is why you can make a pure cross under normal conditions.

reports indicate the seeds wont germinate & I havent tried germinating any myself.

maybe a soak in ga3 will help, or maybe they're sterile.....

My H. jusbertii is in a race with a Setiechinopsis to see who flowers first.

In addition to that Setiechinopsis [which is more closely related to Cereus than Echinopsis] my other options for pollination are Mammillaria, Gymnocalycium, Opuntia, or Lophophora pollen.

Any idea if one of those certainly would suffice to induce an apomictic jusbertii fruit?

I sure could use 4 000 jusbertii seeds, or 100 anyway :P

Those fruits look interesting, almost like minced meat. Have you tried eating one ?

Well my jusbertii fruits aborted.

One got its pollen from Echinopsis subdenudata and the other from Gymnocalycium baldianium. I had high hopes for the Echinopsis. Next comes Setiechinopsis, which itself has a longer flower tube so the pollen can grow as long as a jusbertii flower. Beyond that this year I'll only have Mammillaria, Lophophora, and a variety of old stored Opuntia pollens.

Is there any species particularly good at acting as mentor pollen to induce selfing or apomixes broadly across many genera so we can get fruit?

One guy on a russian cactus forum suggested Hamatocactus setispinus as being effective with Astrophytum spp. as a second best. I at lest have some Astrophytum seed :lol:

1st hybrid seed pod on my cacti this year. Many more flowers to come, but what I'd truly like would be some scopulicola pollen for this one. I'm sure one of you guys has already made that cross, but it would still be nice nonetheless.

it seems i have so many flowers on so many different plants I've sorta lost interest in crossing many of them.....flowers come & go with many wasted opportunities

What did you pollinate your Sub with @Inyan

 

I hit it with a nice red flower I had blooming in the garden.

 

One of the rarest parents I have seen used for hybrids T. terscheckii making hybrid seedlings of that parent indeed very rare and and very much sought after in my mind. Some crosses we make for ourselves though and some we make for others. For me, having a nice red colored flower on a spineless specimen is indeed a nice goal. Now, would I still like some terscheckii or scopulicola  pollen to put to my spineless specimen? You bet your bottom I would. Large, fat specimens that had this dressing seedpod.thumb.jpg.2da72e56f19922bda50f04eb08a686d2.jpg but also stood 20 feet tall and had bright red or purple flowers. That to me would be an ideal worth shooting for. Each parent I could choose of course would have potentially different consequences  down the road. But I do know this little fellow blooms regularly for me in my zone. So, a plus might be a hybrid that blooms for my zone each and every year as well. Another goal.... 

 

Why not hybridize for more floriferous specimens that perform well in multiple zones and areas?

 

So, when I make a cross, it is limited by the genetics I have available, but it is always with an end goal in mind. I don't make any crosses without having some picture of the end goal that I would like to achieve. Now, whether I actually achieve that goal or not is an entirely different matter.

 

Crossing specimens without a goal may give you some interesting specimens, but in the end where are you really going with that line you are creating? What is it that drives you?

I love subdenudata, a real favorite of mine. red flowers would sure be awesome, nice choice @Inyan. My sub hasnt accepted any pollen yet unfortunately but ill keep trying, i think ill have 3 Subs in flower this Spring so ill try some Sub x Sub and as many tricho fathers as i can. I have seen pictures of a Scop x Sub, its beautiful!
