Title: Inducing polyploidy to create new/better varieties of plants!
Post by: ONandONandON on November 26, 2014, 04:28:28 PM


I recently found out about plolyploidy, the manipulation of the DNA by applying a mutagen to
basically double the amount of DNA in the plant, and so hopefully get much better production.
(i read it increases size, and growth, and everything else)

Such mutagens are; Colchicine which is very dangerous occurs naturally in Autumn  Crocus (http://en.wikipedia.org/wiki/Colchicum_autumnale),
WEARING GLOVES, the bulbs can be crushed up with alcohol and water to make the solution.
Also, a much less harmful chemical 'Oryzalin' can be used to induce polyploidy,
SURFLAN A Pre-Emergent Herbicide 40.4% Oryzalin is available, as it SAYS HERE (https://www.forum.haszysz.com/showthread.php?32039-A-Novel-Method-for-Inducing-Polyploidy-in-Rhododendron-Seedlings)

I read that seeds can be soak for 2-3 days in solution. Concentrations of 0.05% are common.
Another method is apply a mutagen to baby leaves, or directly to a cutting made on the stem.

Hope to experiment soon. What do you all think? i have some P.viridis i will try it out on!  ;D

I wrote the same in FDKs thread so long story short:

Colchicum Autumnale did for example help producing the "strawberries" people know nowadays, Fragaria Virginiana was crossbreed with Fragaria Chiloensis and colchidine was used to increase size (sadly Fragaria Vesca only made it into Fragaria x Vescana (dekaploid  :o ) but sadly it doesnt taste like the Vesca - the only ones BC eats).

If anyone wants I can ship a Colchicum, I just have to wait for the right time of the year as they must reveal their position.

Go for it :) I will experiment soon too.

i plan to get the Oryzalin and try with that, the colchicine scares me lol,
but i'd love one or two bulbs, send me a message when you find some.

Should get Salvia Divinorium sent from someone soon, and i'll be trying
it on that eventually, maybe get some seeds, or maybe faster growing.
