Sorry, didn't see this earlier (again). The results of kieki paste on flower morphology could also be due, in part, to methylation state but I didn't test for that. What I did find was aberrant chromosome counts in pollen meiosis. I also found chromosome deletions and aneuploidy in the developing stem on some plants. This is likely the cause of the abnormal chromosome counts in pollen meiosis. This can also occur in untreated terminal buds of old bloom spikes on some plants, especially on some hybrids with chromosomally different parents (morphology of chromosomes not count). Any time you force or speed up growth of tissue in either plants or animals (as in tumors) you run the high risk of chromosomal abnormalities. When one obtains callus tissue from plants treated with keiki past or other plant hormone preparations the tissue generally has chromosomal abnormalities that is why callus tissue it to be avoided.

Thanks, Dean. I didn't notice your reply until now. I was thinking that you were talking about more of point mutation in DNA (SNP, small index etc), and I didn't know that you were talking about the chromosomal abnormality during the mitosis/meiosis. I can see that it is possible, so I'll look into it.

thanks for the update.
In the meantime has anyone tried using such pollen and if so, what happened ?

I intend to test that hypothesis. Tell you more later. :ugeek: This sounds like something we could learn from.
