Ethylene treatment?
    #830098 - 08/20/02 11:32 AM (14 years, 3 months ago)

Has anyone tried a simple ethylene treatment on their cannabis seeds in hopes of a higher female percentage?

In my opinion, i don't believe ethylene treatments help at all in determining sex. Same with stealing birth control from your girlfriend (or mom in some cases) and crushing them up with the seeds. I don't believe that does anything.

Marijuana, both used species, are dioecious. Meaning they have male and female organs on seperate plants. So when male pollen containing the genes for either male or female sex, iis receied by female pollen pstili recepticals a mciroscopic "egg" (the seed) is fertilizeded, and a viable seed is now produced and the sex is already determined. You plant it, you'll either get male or female, treating it with anything or putting hormones in it I honestly don't believe changes anything.

It's like giving your 10 year old son estrogen, he may take on female traits, but he'll never surely be female. There's probably some people who disagree with this reasoning, but personally i believe the biology is there and tells it like it is. You just can't do it. I think these are horrible myths being spread by people with no formal botanical/plant science training.

I think you're right here, ehtylene won't do anything. Some breeders are selling 'feminized seed' supposedly guaranteed to produce nothing but females. I *think* that they're taking female plants that went hermaphrodite and using those 'male' flowers (containing nothing but female chromosomes) to breed with other females, thus producing seeds with nothing but female genetics, but even then, they don't get 100% female plants, usually...

oh yeah, let me add, my above post speaks only of dioecious only and not plants that will suddenly hermaphrodite themselves to monoecious. As i've only ever seen this happens a couple of hand full of times. And is not enough to take any real action over.

i understand this line of reasoning and the biology behind it. i have read reports of breeders getting about 75% females instead of the usual 52%. i am simply looking for anyone here that has tried this. i am looking for experimental info. not theoretical. i appreciate your help.

Perhaps you should send some letters to the breeders themselves and find out, Canada, Switzerland, Netherlands.

oh yeah, another thing, perhaps the seeds themselves are not to be treated, but actually the plants would be. I think it could potentially kill them, or maybe not i'm not sure.

Perhaps (more theory), that the Ethylene causes Chromosomal abberations that in the gamete prudction, spermatogenesis, causes only female genes to be present more than male genes.
Just my thought.

thanks I have also heard of other treatments for plants in the veg. stage too. I just wish there could be more studies on cannabis's reaction to these.

ethylene treatment? - basically some people purport that putting cannabis seeds in with some ethylene ( most fruits give this off when ripening) will cause a larger population of femals seeds than normal. now i know that many claim that this is basically pseudoscience but i am looking for real data.
