Very interesting information, thepaan.

I sure do wish they did all that research with cannabis and rice, instead of arabidopsis and rice.

It seems, from what I've read about this on web pages you have provided and ones I have found, that different plants use this mechanism to produce flowers at different times or day-light/night lengths. I would guess that the timing of flowering, that was evolved in each respective plant species, was determined by its survival strategy. Early bloom must have an advantage for one plant while late bloom has an advantage for the other.

It would be nice if there were scientific studies on this in the cannabis plant. I doubt many, if any, of the people who grow cannabis, have the resources to do that.
