I believe all of our girly mj's are capable of showing both sexes, part of their dna. when environment is right, or wrong, their hormonal messages change and in a last ditch effort(heh, pun) they will express a boy part in order to make a seed in order to continue their down line.
I believe that the sensitivity can be bred out, I do not believe I bred anything out of the dna, but I did interrupt the messages, and it has lasted hundreds of generations, while the originals were confuse almost right out of the gate in a well controlled environment. Why did it work? I could give two shits. that was awhile ago.
Then I dusted off the bottle when I saw these new Topdawgs throwing balls, not many, but every plant! Honestly I think someone could have managed the crop with manual removal but I cannot, and dont have any patience for confused plants in my garden spaces.
why would I spend years with a punnets square trying to dial this trait out of my line, using up precious plant counts, uncompensated resource costs, etc....when a 50 cent treatment will do it right? Its a popular greenhouse treatment that works on many of our fruits and veggies we buy daily. Once I find or make holy grails I store them forever as cuts, or keep them growing till bored, clone from a clone, mom, whatever. I do understand stabilizing genetics for commercial applications, personal funs too, and am wowed every time I hear someone taking on the task.
-I should have put bred in italics on my last post...it was tongue in cheek. I dont breed anything except bad habits these days.
