Sugar demand, not auxin, is the initial regulator of apical dominance

Would it help to add sugar when decapitating all shoots?

Like taking cuttings off a mother plant?

I am not sure I understand how this works.

Hi guys

Hey if you are in the experimental mood, you could try this technique:

Put a flexible, opaque covering on the primary shoot, covering it in a way that no light gets through, but gas exchange can occur.

Do this to a vegging plant when it is small. What happens?

Do it to a more mature vegging plant. What happens?

Do it to the terminal cola of a blooming plant. Try it early on, and later on too. What happens?

What happens if the covering is only partially opaque, letting in some light?

Consider your results though the lens of the concepts in the paper in the OP.

What is going on in the plant when you conduct the experiments?

Have fun! Knowledge is your reward.

Adding sugar might work if you A) gave it by infusion to the lateral buds and B) prevented it from draining away into the apical one. Conclusion: with the knowledge we have, you can do shit about it :D .

Shading the apical part will only make it stretch in a vain attempt at reaching light again. Waste in energy, resources, and time (and more importantly, the apical but will use up the bit sugar produced by the lateral buds too and keep them even smaller as usual)... but feel free to try; there's never enough theoretical reasons not to perform some experiments!

Shutting down sugar production in a localized fashion by modulating photosynthesis?
