whorled phyllotaxy is neat but is usually transient and doesn't mean anything IME.
"transient", I like that. The difference with my whorlers opposed to those that start as tricots and grow out of a temporary tri-whorled phase, is that mine start out as regular and start whorling later (4th node - 11th so far). Some branches on some, most on others, topping or bending the main stem actually encourages that.
The wp in tricots however is often just a logical result of three cotyledons, following "The Hofmeister rule: new organ primordia are placed in the widest available gap in the meristem, as far away as possible from preexisting primordia (Hofmeister, 1868)."
The models in the image attached depict that nicely. First is regular/decusate, second spiral, third is triwhorled/tricussate.
Ime it does however mean a few things. Tri whorled is in theory clearly better phyllotaxy (in terms of spread and direct light) than regular opposite. With regular leaf 5 and 6 overlap 1 and 2, with triwhorled the first 6 leaves don't overlap. Each successive node is rotate 60degrees (hoffmeister rule). Nice in theory, but also in practice, especially during veg. They don't necessarily veg faster but do create more "plant" at the same rate which in practice when doing some canopy control can in practice mean being able to fill the room faster.
I've long refuted they yield more, I've tested it amongst plants and even on the same plant (tri vs regular bud), and after being about to finish a run of generation of which more than half are whorlers (originally started out with a quad, crossed with 4 strains), I got to say, it depends. A tri whorled bud (made up of many small clusters of calyxes) isn't necessarily larger than regular, but a tri-whorled cola does have more bud than a regular. Also once alternating tri-whorled has more internodes than regular (spreading out 3 instead of 2).
That said, only so many buds and so many leaves one can put in a given space which can be done using regular and tri, so all in all, it's really not about more yield. The benefit during vegging is a matter of days not weeks difference.
It's above all "neat" and I find the way how they develop (mine go from regular to whorling by throwing one divergent leaf at a golden angle first) fascinating. It's just a hobby. The trait is usually early to spot even though they don't start out as triwhorled, so I can run more than a couple of dozen and actually get some idea of the ratios.
Plant in pic is non-alternating, so all three still on same level. Those that I veg long enough to mature start alternating and basically turn into spiral phyllotaxy.
