Thanks for your comment. Yeah - I was happy that they were all negative. I am very aware of virus spreading and I try to be careful but I have heard horror stories about people's collections being just decimated due to virus spread. I have been putting these tests off for a while but I am so glad that I finally did this.
It was so easy to do - I was thinking about having a virus testing session at one of my next members meetings. Or talking with AOS about having them sponsor a session at a meeting...
Thanks for your comment - I am glad that you liked the video. I have been meaning to make this one for a while - I just did not want to deal with virus positive plants - luckily, I was OK. Maybe others are procrastinating for the same reason?
Thanks for your comment - yow - that is an excellent question. I do not know for sure. There are a few possibilities: 1) My virus test kit is for the two most common viruses. There could be others affecting the plant. But, I did not see other aspects of virus infection in this plant. 2) In this plant, the genes for purple pigment formation may lie in an area of the chromosome where it is turned off, but inconsistently. This is unusual but it happens. This is called gene silencing and is common in plants but may be unusual in flower development. 3) The same gene is interrupted via a transposon or jumping gene - again, unusual in orchids but it happens - discovered in corn by a scientist who was awarded a Nobel for her discovery... 4) Not sure about the layering of cells that give rise to flowers but this may have resulted from a chimera, or a mixture of cells that did not sort out correctly when the flower was forming. Does this help?
@@plantpropagatortransposons, Barbara McClintock, if that is the case, it would be very interesting. And now you are free to cross it and explore the mutation, imagine this plant crossed to one of yours peloric cattleyas, what would come as a result 🙃 Thanks a lot for the video and I hope you use the plant in a cross, maybe a self if you are still concerned it carries some other virus
@@PL_Brazil She is one of 3 Nobel Laureates that I have met and was very nice. I do not think that I will use this flower in any of my crosses - I have the pollinia stored but the flower was just weird and I am not sure that I want to deal with that. I have plenty of other crosses to make.....
Thank you for sharing information with us and for the examples.👍 Great news for your orchids!
I have been hesitating on doing this for a while so it was time to move forward! I am glad that the tests were all negative. Thanks for your comment!
Thank you for sharing this with us. CONGRATULATIONS!!!! So happy they came out negative.

Wow it’s so cool how you tested! One day I’ll try it. It’s not worth risking the whole collection. Thanks for showing us!

Thank you, John. What an informative video!

@@plantpropagator I know the feeling of relief when a suspected plant turns out to be clean.
Very nice they are not infected!!! But why the lip color is unstable?
