Some more whorled thoughts...
"Phyllotaxis is the regular positioning of lateral organs
around a stem (Kuhlemeier, 2007). The divergence an-
gles between successive organs are species dependent
but most frequently tend toward 137.5°, which results
in spiral phyllotaxis. The 19th century German botanist
Wilhelm Hofmeister was the first to meticulously de-
scribe a property shared by almost all phyllotactic
patterns, now referred to as the Hofmeister rule: new
organ primordia are placed in the widest available gap
in the meristem, as far away as possible from preexist-
ing primordia (Hofmeister, 1868)."
Phyllotaxy is leaf arrangement and to catch most lights the leaves should obviously be arranged in such a way that there's as little overlap as possible. With 2 leaves at a node on cannabis plants this Hofmeister rule automatically results in opposite phyllotaxy.
With 3 leaves per node, i.e. what I call tri-whorled, they should be evenly spread with a 120 degree angle in between them. That is NOT always the case. Alligator also posted one of those where 2 of the 3 are sort of on one side, and there should be 2 on the opposite side to spread them evenly, but instead there's one. Perhaps described by Hofmeister in his complete work, but it's not as consistent as the word "rule" implies. When the sets after the first neat whorling nodes don't follow the rule, the auxin regulation is not consistent enough, it's simply put unstable.
Makes it imo even more beautiful that two nodes of three leaves each don't overlap in tri-whorled. The plant essentially rotates the next set 60 degrees. This just shows how accurate it is in finding the widest gap available.
Anyway, I haven't had a tri-whorled that didn't start with that divergent leaf leaving enough space for auxin to accumulate and create a third, it's for my whorlers a requirement. As a matter of fact, it's the only requirement, the rest happens automatically according to the Hoffmeister rule.
I'm currently harvesting pollen from a CHxCH tri-whorled male. Looks like one of the other two I found recently is male too. I like that one better so will probably use that one instead, or both. I will continue to try and get a whorling line from my current breeding stock, but I have to say that looking for tricots is starting to become more and more attractive. There are a few breeding techniques that would be very suitable (because the trait can be spotted as soon as it germinated I could run more than a couple of dozen).
