Difficult Question, Flowering Hormone?

Would putting a bag over a side shoot every 12/12 cause just the
covered side shoot to flower, or would the entire plant flower?
Because I read somewhere that if you were to graft a flowering
side-shoot to a plant that isn't flowering,it would cause it to flower.
Because theres supposedly this hormone called "florigen" that exists in latent form during vegetative growth of all flowering plants. Triggered whenever the plants flowering method kicks in whether by long nights, long days, temperature, etc. And its sole responsibility is causing gymnosperms and angiosperms to flower. And supposedly it exists in the leaves of flowering plants, and when grafted internal tissue of the grafted shoot and the main plant comes into contact, and the "florigen" from the grafted flowering shoot gets carried over within the non-flowering plant and sigals it to flower.
Hence if the entire plant flowers via single flowering side shoot covered with a black bag and under 12/12 photoperiod, or a grafted flowering side shoot from a different plant, it would prove the existence of this "florigen" right? And if the plant doesn't flower via 12/12 covered side shoot or the grafted flowering side shoot, it would disprove the theory on this "florigen".

Just got too high and started thinking, any takers? If you can understand it.

dude. that's a great question. i think it requires experimentation.

but i'm not sure it would 'disprove' the existance of florigen if that grow tip didn't flower.

im waaaay to blazed to getchya 100% but i know that a branch covered to give it 12/12 will flower. ppl do that alot to find out who the chicks and and dudes are. or they will spray 1 branch of a known female with gibberellic acid and cover it 12/12 to make it a male branch. that way they can nab some pollin for breading.
dont know if that was what you were asking but hope this helps lol

But as soon as they find out the sex of the flowered side shoot, male or female, they would immediatly place the entire plant under 12/12 or chuck the males. Therefore not knowing whether the forigen passed between the flowered side shoot or not. Because if you threw the entire plant under 12/12 as soon as you found out sex, maybe the plant didn't have time to recognize the florigen from the flowering growth tip, and didn't have time to flower because of the transfered florigen from the flowered growth tip. And because you chucked the males or placed the females under 12/12, all the leaves release this florigen causing the entire plant to flower, therefore not knowing whether or not flowering was initated via 12/12 on all the plant or via florigen from flowered growth tip.

ill have to reread up on it, but i seems to remember a few folks on OG keeping the 1 branch on 12/12 just to get pollin from a good mom plant leaveing it on 12/12 untill they get the pollin they need. but leaveing the rest of the plant on 18/6 to veg it up to a size that clones can be takein. but dont hold me to that. OG went down quite a while back and i havent read much on it on any other site.

Here, read this, this kind of gives you background on what I'm trying to say, also a good read and good information.
Flowering

Photoperiod

Photoperiod is detected in the leaves. The cocklebur, drawn here, needs at least 8.5 hours of darkness in order to flower. Even if only a part of one leaf is exposed to the correct photoperiod, the entire plant will bloom (middle figure).

The leaves produce a chemical signal — called florigen — that is transmitted to the apical meristems to start their conversion into floral meristems. The right-hand drawing shows that grafting a cocklebur (B) that receives the required period of darkness to one (A) that does not causes flowering in both. Evidently the florigen signal passes from B to A through their connected vascular systems.

Hey fix the link to the research. I wanna read it really bad.

Last I knew it had not been confirmed that florigen exists (or even what it is, how its created, and how its used), and last time I looked was ~February for a plant physiology class I was in.

I'll try digging around some primary literature databases tonight to see if there is anything new.

Fixed it, here it is again:

well i have heard of ppl puttin a bag over the lower stem to see which were males an females..they then put the females totally under 18-6 to finish veging....this works well if your growin a number of plants for an extended veg cycle...2 months...
