We all already know how to stress/kill salvia plants. Image
Discoveries related to improved yeild and increased salvinorin content would be much more valuable than different leaf shapes and I am sure that many people are working on this already. It would be great to have some new super potent salvia strain. Although 1 am only growing the Blosser and Hoffman-Wasson strains 1 am fortunate enough to live in a location that is both environmentally and politically favorable to salvia and now have more plants than 1 need. Stress testing is a good project for those with a green thumb and a few plants that they don't mind killing. And just for the record I have not killed any salvia plants so far.

Now that's what I call a mutation.

Hey daivlas
I have a thread here somewhere called "Me and the mutant". It's more of a long story about me really, but it includes the effects of GA-3 on Salvia.

It caused at least 6 tiny plantlets to appear at every node on the plant. Interestingly, on my 8 inch plant, I got about 20 plantlets big enough to root and which are now living as separate sallies.

Eventually the effect of the hormone wore off and my mother plant has reverted to normal, but with much more leaf and stem growth than I would have expected. I have had to move it to a 20 inch pot from its original 6 inch pot in 3 months. That is significant in my climate. A lot of bad things happened too, like roots appearing on upper branches, various bits of death, and so on. Interesting, though.

Also, according to this:
Agrobacterium can cause plants to get a sort of cancer. This:,4-dic...oxyacetic_acid
can also cause some sort of plant cancer.

If you have plants to spare and no moral qualms I would recommend experimenting with auxins and plant hormones that can be bought safely online. Certainly just as good for the plant as burning it, right, if the name of the game is exploring its potential and discovering new knowledge? Some of these hormones are dangerous to people, of course, so be mindful of that.

I have a big UV light, strong enough to cause sunburn to me when I accidentally exposed my arm to it, that I might try pointing at some plants some time to see if it causes any results from DNA damage.

Hey zhqhqhn, that was a really long post but an interesting read. Unfortunately I was unable to see the photos of the effects that GA3 had on the plants. Wondering if the significant leaf and stem growth are a lasting result of the hormone or the result of the 20" pot. I am not big on auxins, hormones or even fertilizers for that matter, just looking for ways to activate existing genetic codes for variations in appearance. I look forward to seeing the results of your big UV light test.

The split leaf seems to be more of a common occurrence that I had first expected. Another plant of a different strain produced the same type of forked leaf as the first plant and the photos of the new leaf are below. That plant was over pruned as well so it seems that this could be the cause but I can not say for sure. A clone of the first plant is growing but has not produced any forked leaves yet. Once it is larger it will be over pruned and observed to see if that causes any abnormal leaf growth.

getting out of the understory is a real pain though....

Is that Les Stroud?

No. That's actually the opposite of how Darwin coined 'natural selection.'

FIRST come the genetic variations (by Darwinian definition-at random) THEN come the environmental stressors that may or may not eliminate or favor mutations that are ALREADY able to help the organism survive the change(s) in the environment.
