cross breeding with different species

Post by **daiv** » Mon Jul 07, 2008 5:26 pm

Yeah, I learned that here - from Ian I think. But that the self-sterile plants have inhibitors that don't allow its own pollen to work. Then the inhibitor is removed with "foreign" pollen which makes it receptive to other pollen as well as itself.

(I'm sure I have the right in concept, if not in language.

)

Of course it never happens when you're desperate to get some seed from that one very special plant!

Hi

I have been reading through this forum for quite some time but this is my first post.

This is the first time I have seen any forum discuss this actual technique.

The concept of inducing "Selfed" seed on self infertile cactus by using foreign pollen.

Is this relatively foolproof and would it work on my scopolicola? I have been looking for a seedparent to match with mine for producing true to type seedlings without any luck and scopolicola aren't that commonly distributed around here.

If I understand the concept correctly, Would that work if I say, take a mammalaria or lophophora's pollen mix it with the scops own pollen to pollinate it in order to encourage it to "self" it's "self"

?

Could I have some examples including species used that has successfully induced this behavior? Or are there cacti I should consider that has a strong tendency in it's pollen to overcome this barrier?

nothing is fool proof, especially with plants!

Use something that is extremely unlikely to cross. Certainly pick a different genus, maybe go as far as an Opuntia. Or buy some seed

Thanx

Funny you mention Opuntia. The Opuntia idea did pop into my mind a couple of times yesterday.

I shall give it a throw.

Let us know how it goes too! I hope it works!

Gio - you have some mind-blowing Astrophytums!

Crossings are made by Paolo Panarotto.

I was about to start a new thread with my questions, but this thread answered them quite sufficiently!

But i am wondering if this worked...

I've recently crossed Echinocereus fendleri v. kuenzleri with E. viridiflorus. Mainly cause they were open at the same time, but i thought a really big green flower or a really small purple flower would be really cool! (i doubt it works this way, but i like to dream) I also thought the morphing of the different spine types might create something fun.

The E. viridiflorus has set fruit, so something is going on. I did not pollinate the fendleri, as i was hoping the others would open flowers at the same time...but they didn't

Another cross i tried was, Loph williamsii with Strombo disciformis. This was unsuccessful, but next time i'll try the reverse and see if anything happens.

My next attempt is Opuntia. Since our O. poly v. erinacea is now flowering, along with our C. bigelovii... eh, it's worth a shot right? or am i dreaming again? I haven't heard of any Opuntia x Cylindropuntia hybrids before, so i may be wasting my time...

That fruit you got might be a self pollination job that was accepted due to the foreign pollen. This might have enabled the self-pollination in other words, not made the pollination, but I don't know on these species.

Ya, hopefully the potential seed is viable and in a year or 2 we'll know what happened

can the pollen be kept for a short time while till the intended recipient flowers?

Thats a good question and i would love to know this as well... Can we keep the pollen for a short amount of time or for X amount of days.
