Re: Graft chimeras and Pereskiopsis without glochids
Hey! I have to say I really liked reading your grafting thread as well. I'm working with Ariocarpus fissuratus exclusively for my chimeras. Any updates? I managed to make one of my own, with a. fissuratus. I have a dozen grafts with a. bravoanus and although they look like they would be chimeric, n...

Re: Graft chimeras and Pereskiopsis without glochids
I use pereskiopsis a lot in grafting and think it’s one of the best stocks for seedlings but absolutely can not stand the glochids. Over the years I’ve experimented with different ways to remove them and think I might have finally come up with a permanent solution. About a year ago I made a series ...

Echinopsis seeds not germinating
I sowed a bunch of e. mirabillis seeds last year and this spring too, but every time almost no seeds germinate, in this years case ZERO. I have the same problem with e. oxygona. My friend sowed e. mirabillis in the exact same way as me and every single seeds germinated. I don't get it...do echinopsi...

Overcoming self-incompatibility
I've been searching the internet for hours on methods that can be used on cacti to promote self fertilization in self-incompatible species but I found nothing. Does anyone have any resources or knows of any methods that might work? I've tried cutting the stigma at a sharp angle and then dusting the ...

Re: Cactus hybrids
In this case Echinopsis pollen might just been used for stimulation of Echinocereus to self-pollinate. If you grow seedling from those seeds will be clear are these hybrids or pure Echinocereus poselgeri offspring. Interesting, I'm actually looking into ways to self-pollinate self-incompatible spec...

Re: Cactus hybrids
I crossed echinocereus poselgeri with the common peanut cactus (echinopsis chamaecereus) and there are fruits with seeds. Echinocereus was used as a mother plant and it's making fruits.

Re: Rapid plant movement in Cacti
I would say your theory is probably correct. It is an example of thigmonasty, various plant responses to touch. Many cactus flowers have this, including Notocactus , opuntioids ( Opuntia and Puna , definitely), Pediocactus and Pterocactus . Here are some videos: https://www.youtube.com/watch?v=cag9...

Rapid plant movement in Cacti
When this opuntia's (most likely stricta) flower is disturbed, it rapidly pulls all disturbed anthers towards the pistil and in the process self-pollinates. I just noticed this today and I'm amazed, what could possibly be the reason for it to do this? Normally cacti avoid self-pollination/fertilizat...
Re: What now?
Thanks anttisepp and Carbo! It's in a 3.5"/9 cm pot. That's interesting about pot size. I'd never thought about that before. Have you found the size of the root system affects the character of the scion (especially in terms of amount of offsetting) or just the speed of growth? It's a huge effe...

Re: Why do you graft?
I graft Young seedlings, 1~2 months old after germination. There was a professional cactus seeds supplier but he finished his business and I can not buy cactus seeds in here now. Some people import cactus seeds but I do not because importing of plant related materials is very hard in here. My purpo...

Re: Why do you graft?
Carbo; thank you for an informative answer :) Interesting that the Mamm you are referring to reacts so differently to the two species of rootstock and how much impact that have on the flowers. The Mamm mentioned is a monstrose form , would the same apply to normal forms of cacti? In the pic in the ...

Re: Sand vs. grit
Grit is gritty and sand is...sandy :D I don't think there's really any concrete meanings behind those terms. But you can pretty much use anything that's chemically stable as inorganic addition to your substrate. I've found over the years that smaller grain size is not good, not enough oxygen (air) g...
