  1. There is one methode that uses small metal particles with DNA fragments attached that gets shot into a bacterium with pressure. Maybe thats the methode you have in mind. With plants or animals its a lot harder because of the more complex genom organisation and the nuleus. The next step to introduce new genes into a plant is via the modified plant patogenic bacterium or a virus to create transgenetic plants. The hybridisation is a less radical approach which often occures naturally with many plants. As far as I know all cacti have the same chromosom number, so they might theoretically all be able form a zygotes with each other when some species specific fertilisation barriers are bypassed...with an electrical shock for example

  2. Interestig concept. Since to my limited understanding cell/cell interaction roughly depends on electric potentiales of cell membranes and their proteins it makes sence somehow. Do you know if the direction of the electric current matters? Should I plug the pollen on the + or on the - ? :)


  3. Hello SAB, I want to show you some of my plants.

    I started growing Trichocereus 5 years ago from seed, so my collection mostly consists of smaller plants and seedlings.

    These two plants where both sown at the same time, one was labeled T.pachanoi and the other T.peruvianus. The seeds came from a german vendor. I lost track whit the lables on these unfortunetly

    The peruvianus type plant developes black rot at the tip in the beginnig of every grow season and then it does funny things with the ribs every spring.

    This is the other plant. I don't know how to name it, looks a bit like everything I think.

    The plant this cutting came from is dead now, and I'm happy I saved this piece. It took two years to send out roots and a pup. I think it is a bridgesii form, but i'm not shure, the mother plant was all cork and had almost no spines

    I hope you like the plants, I might post some more here soon.

  4. Hello! I have heared that it is possible to propagate Psychotria via leaf cuttings. I have fresh leaves and I have planed to put them in soil and keep the pots moist in a baggy until roots emerge. But I have serveral questions.

    Does this sound like a good procedure you think? Is it possible to make several cuttings from one leaf? is it important which side of the leaf is in the ground? Do plain leaf work at all or does it need a meristem at the base of the leaf stem? Thanks everyone for input!


  5. wow, those are very amazing!

    Hey, anyone knows that this stock is?? I think it rules! And fact that it swelled kk339 is indicative, as is the growth of a freelance plant I got of this stock. It's a climber and grows and roots quickly. Shape and spines are very convinient too.

    that stock looks like Selenicereus


  6. probally a seed grown bridgey. Be easier to tell when she gets bigger.

    LOVE

     

    Thanks mate! Yes , those are seedgrown, I knew that spination can look different on babys than on adults. Whats got me thinking is that tendency to develop central spines, I thought bridgesiis don't have that.


  7. Hello! I would like to know what you think of this. At first it looked like bridgesii to me, but then again it looks different. Maybe its a cross? Some areoles have up to 6 spines with one large cental spine. Some spines are swollen at the base. Colour doesn't seems alright for bridgesii I think from net pictures, but I have no confirmed bridgesii here to compare. Have you seen plants like that before?

  8. man I think I love cacti at this stage... When they first exhibit their first mature traits- this when grown from seed. I think I can spot a V sign too in some areoles. Looks very nice and interesting!

    Why do you say it's not at all glaucus? Are the photo colours messing with my eyes?

    In any case, letting it grow a bit more will help the potential educated guesses.

     

    Thanks for the response! It not very blue, but the light in here is not great for photos. In day light, the colour looks more like on the flash light picture. It has some V on some areoles. I'm very happy it looks like a cactus finally, its from the first batch of seeds I grew successfully. Can't wait to watch it grow next season.


  9. Hello everybody!

    Thanks for having me on your Forum. I love watching the cactus pics here :)

    I think you do, too. So I show you one of mine, even its not very impressive at this stage. I planted it three years ago. It is supposed to be a pachanoi. I know there are types which have long spines, but this one has up to 3 cm long spines, while the fattest part of the stem is only 5.5 cm thick. Its not showing glaucusness like my other Trichos at the same age. What do you think of it? Too young to tell?

  10. Thanks for your input! So I will get me some seeds and start them soon. I was actually hoping it would be bridgesii-like, showing some traits standard bridges don't have. But the Lobivia pentlandii that Evil Genius posted looks very cool and worth growing as well, and even if T. boliviensis is just a standart bridgesii, I will grow it to have some more of them.
