I got seeds!

Bluefunk, here is your answer:

Plants do not work the same way mammals do. Once a female realizes that it has no chance in being pollinated, it can, in certain situations (i.e. careful stress), produce seeds that are basically clones. These women are called XX females. Every seed will be a female. This is a very rare thing, but can be done. I'm not sure if there is a post about how to make XX females, but I've read a pretty good amount of material on the subject, and it is, as the hairry gorilla said, caused by stress. There's a largely more detailed way to create them, but, seeing as how that was not your question, I will not waste anyone's time.

Here is the scientific theory behind XX females:
When stress is administered to the marijuana plant, it will, in an inherent attempt to keep the species alive, become a hermaphrodite. Hermaphrodites are self-pollinating plants, meaning that there is no other genetic code besides that found in the hermaphrodie that leads to its growth. However, a very small number of plants are not able to become hermaphrodites. As much as they try, they cannot expel pollen, and are only capable of producing seeds. Those that grow these seeds say that the two plants are complete sisters, cloned from seed rather than stem. It is much easier to produce these special females with indicas, though it can be done with sativas.

I hope this information can be helpful to you, bluefunk. If there is anything else you need, don't even hesitate to ask.

If any of the information herein is wrong, and anyone is able to prove thusly, please post the correct information, as we all must learn.

Brilliant thank you graph, an inciteful and scientifically logical explaination makes perfect sense.

Where'd you come about this information?
:question:

If it's an Indica dominant trait, it would explain why information on the technique has been late coming to the west.

However....

This is a very rare thing..... a very small number of plants are not able to become hermaphrodites.

None of my plants have ever been hermie. All of my seeds have always been female. Thousands of plants and thousands of seeds. I only got them when I stressed the light cycle. Was I just lucky?

Those statements don't quite jibe.

Is it rare or not?

It is rare unless you are producing female seeds. It doesn't happen for no reason. Call a seed bank and see if they will tell you how to produce female seeds. They dont plant them then go back in time after they know the sex to sell it as female that would be to expensive. They do not sell hermies as females either. All I can tell you is do it for yourself.

One love

graph, you've got me thinking. How would a plant lack the ability to turn hermie? If it has XX chromosomes then it has all the genomic DNA that XY seeds have. Does it lack the necessery transcription factors? does it exhibit an alternative splicing pattern to XX seeds? I'm curious, plant genetics is not my faute in molecular biology but I can readily learn.

[Sinsemilla Jones]

Then you would have to be lucky to get only females that went straight to seed, if such plants exist.

Alright, I'll try to answer these questions in the order in which they were asked.

Sensimilla,
As the gorilla said, it is rare if you are not planning on this happening. However, there is a certain technique, used by putting a very ordered stress on the plant, that will cause this phenomenon to happen on a regular basis. However, if it has never been done before, it may just be luck. This plant does exist. I understand your skepticism, but many growers have accomplished this, and it is the only way to guarantee female plants.

Bluefunk,
It is a combination of the stress and the genetics that makes it so prone to becoming an XX female. I have read two different articles that insist that it is the genetics that creates the female, while another implies that it is the special stress. Some sources say that XX females are easier to find in indica strains because sativa strains are so much more prone to turning hermaphrodite, but I cannot confirm this. I have found no scientific evidence on the marijuana plant that shows the biological process by which it becomes an XX female (oh, how prohibition inhibits good research), but from what I know of other plants, it probably has something to do with an underdeveloped stamen. If anyone knows the scientific process by which this occurs, please post. I would be interested in finding out as well.


Karma, do you use the gibrellic acid and natruim hydroxide method? If you do, does it work?

Sorry for the double-post, but there was a few things I missed.

Senemilla,
My sources are compiled of a list of dvd's, books, and these forums! However, all of the information I have found on the XX female has been found in books. One of them is an ebook, and if you are willing to create an email address or already have one that is unrelated to your main email, I would be more than happy to send it to you, free of charge. I'm not sure if there is a post about how to create an XX female, but if you would like, I can do that for you as well.

On the other hand, my foot tastes delicious! (My foot on the other hand?)


Just the fact that you haven't started calling me names, convinces me that you are probably right.
:thumbsup:

Really, you have my upmost respect in the way you've handled my skepticism, a rare thing sometimes even for those who know what they're talking about. Thank you very much for your understanding!
:clap:

And thanks for the offer of info, if I get the time and inclination to study it further, I might take you up on it. But I haven't ever disclosed any sort of e-mail addy on here, temporary, "secure", or whatever, and my spideymite sinse tells me I shouldn't start.

I'm sure everyone would enjoy a thread on it though!
Who cares if it's been done?
A 2nd thread on XX females would definitely not be overkill.
:stoned:


c - Thank you too for not dog cussing me, gives me hope that all your tales might be true! Hope you also understand the need for cyncism around here. The BS just gets soooo thick sometimes. My apologies for my 20th century brain, and my best to you in fighting the powers that be!
:rasta:

Alright, will start that thread as soon as I get some time on my hands. I understand your not wanting to divulge personal information, by the way. I pretty much feel the same way. The thread will cover all of what I was going to send you, though, so there you go as well.
