Can All Female Cannabis plant produce VIABLE male flowers?

is all cannabis genetically predispositioned to hermaphidism to varying degrees of course?(depending on what conditions it take to make male stamen form from GA to stress.)

and Why?


this is the best paper i could find, its not about cannabis and it explains both theory's about hermaphroditism being both possibly a trait or genetically predisposed.

a lot those answers are stemming from evolutions of dioecious plants from hermaphroditic ones, this would explain the ability for any female to produce male stamen, but this does not mean they will be viable, if their pollen is not viable, then does this make it a true female?

heres the paper you make your own calls
http://www.simonqueenborough.com/uploads/1/0/0/8/1008315/bawa_1980_ares_evolution.dioecy.pdf
so i guess i want to apologize because if the papers are correct that im reading, because if all dioecious plants evolved from hermaphrodite ones, that means all females are technically able to produce male flowers(viable or not), and it is not trait like i had believed, it is ingrained genetically.

does this change much to me or my breeding? no because the amount of predisposition to hermie can be bred to a controllable extent, which still follows along the same path of treating as a trait in a breeding program.

i would also like to point out was correct on another point i made.

mutagens are the only way to get male stamen from female plants. CS, Stress and light poisoning only ensure you males stamen with female chromosome.

oh and i admit it completely now, i was wrong.

all female cannabis can form male stamen, the viability and chromosomal containment of the pollen depend on many factors, hermaprodism is not a trait that can be bred in and out is ingrained in the chromosomes of all female cannabis. so once again sorry peeps the way its often talked about is not thorough and express it as if it is a trait.

like always, learning something new.

i'd love to know the answer to this one poly, maybe you can help me out as no one else has been able to give me a satisfactory answer thus far..

here goes.. :D

is sex in seeds predetermined or can a seed be either male or female?? my theory is that they can be either, how else can you explain hermie plants, unless of course a seed is hermie from the get go, but i don't think that to be true..

well from what i understand now, a female plant can be a male or rather be forced into producing male stamen only.

a male on the other hand is a male, the only way to get any female traits from a male is to have a extra chromasome like a polypoloidy and actually this is what i used to start breeding was a male herm, male hermies are also able to go on and self seed with both male and females. unfortunately i did not self seed i used it for crosses.

so what i would say in females, you have the ability to play with it a little more, able to determine the sex the way you wish based on the factors involved with growing it. but sex is still predetermined female is female even if grown like a male:)

some females (although i did not mention this in the above statements to prevent from mucking up things) can produce male stamen (xy chromasome) even without mutagens. less common, but it could happen.

yah poly, i get how the whole hermie spleal works and that both males and females can grow the opposite sex flowers, and that male to female hermies are far less common then female to male, i'm still a bit confused as to whether a seed is predetermined to be a female or male before germination, or do environmental factors play a factor in seed sex much in the way that they do in say sex with alligator eggs?
i've seen on tv that a certain temp range for alligator eggs will give you females and i think a bit higher range will produce males from the same eggs..
i've also read in the grow bible where jorge cervantes says that certain factors like high nitrogen, higher levels of hunidity and a few other things will influence seeds to produce more females then males.. i'm not the biggest fan of jorge, so i don't take all that much stock in his theory, although i've yet to really get a satisfactory answer either way on seeds and sex, predetermined or not..

yeah, but rather i think the words where just simplified so he did not have to explain the entire genetics of cannabis, you would be surprised how many people get hermies and think thier males. the only way to really know is to pick some balls off, or stress it out a little, or even change the feed to see if it sprouts hairs.

i know i keep my general parameters around what is considered optimal for female productions(blue light, high N, and humdity ect) because imagine you veg under hps with some seed, and veg with bloom fertilizer, i would think a females seed with a disposition to herm, may grow and act male 100% even though genetically speaking its still a female.

so technically without gumming things up lets call that female a male. i think sex i predeterimind, i think female sex can be influenced, males take up a lower percentage of the pop so it make sense that if you follow the rules (and i have) all your female seeds would grow as female, and all your true males will expose themselves.


heres a male from under all the proper "fem" condition, blue light T5 with x2 460nm bulbs x210000k and x2 50000k,has only received 3 feeding all high N, and only fimed once late into veg after sex begun to start showing and i though it was male.

these balls came on fast after getting under that HPS.
