im not talking down to you in particular when i say im talkin to a wall its just that ive had to say the same thing 3 times now.
you're misconception stems from you not knowing that when you LST a plant, the nodes grow branches...what were once budsites now grow an apical meristem.
you also seem to think there is difference between a stem and branch?
there are 2 type of branches lateral and apical.
lateral branches receive a growth inhibiting hormone.
again the "two stems" you speak of are still achieved with LST, and perpendicualr to those two stems is the ex-apical top.
it is now receivin the growth inhibiting hormone.
Let me draw you a picture....
FIRST PIC:
a plant grow from seed that was topped
notice the "two stems"
Second PIC:
same plant from seed LST'ed
notice your "two stems" this is where LOL came from
Third Pic:
Clone LST'ed
see how all the lateral's become apical?
now for the kicker:
Topped Clone
see how only the top node beame apical
yes if nodes are tight you may have 2 nodes that share dominance, but still the fact is that there would be 2 shoots per node if the phyllotaxy was decussate which has been the point from the beinning.
Hopefully now you see where lst still has the same effect as topping without losing the top
(you do know that where you cut the stem NOTHING grows from that right??)
