TerryTerry, that’s a nice clone but to my untrained eyes I cannot see anything obvious that screams tetraploid. Conversions can be very hit or miss.
Nothing is guaranteed. Many, some or none of the seedlings can be converted.
I understand tipo as meaning nothing more that ‘type’ or common form of the species.
I think that we need to ask our resident expert!
Tipo means the most common colour form that is occurring in the wild. It doesn’t refer to polyploid status.I don't think the plant growth or flower are saying polyploid. Certainly different from the known tetraploid trianae it is sitting next to. I know what colchicine does to patients - a little doesn't relieve the inflammation and too much causes toxicity. It isn't always easy to get the Goldilocks dose. When we used colchicine a lot for gout we would say increase the dose until diarrhea is just starting and then back off. I think the same has to be true in the flask - too little and you just get the regular plants (in my case just a cross of two "tipo" trianae) but too much will kill the sprouting seedlings. I think that oryzalin, an herbicide that also disrupts microtubules involved in cell division may be a little more reliable at producing polyploids and may be safer for the lab people. I think that is what Orchids Limited is mostly using now when they are trying to produce polyploid plants.
In the end, I am just wondering if those of you with lots of trianae experience would put my flower in the "tipo" range! In simple terms, "just a regular old trianae".
