Learned some stuff.

Auxins are one class of hormones, and are produced by the apical tips, new leaves, and flowers. Auxins are also transported to the roots, where they're responsible for new root growth. They promote new leaf and bud growth at the tips and suppress it in the lower growth.

Cytokinins are another class and work in ratios with auxins. They promote the abandonment of older growth and counterbalance auxins. Cytokinins are produced in the roots and new growth. A high auxin/cytokinin ratio promotes root formation and a low ratio promotes shoot formation.

And the product of photosynthesis is glucose, which is distributed throughout the plant.

So, if I'm thinking clearly, once a leaf has stopped growing, it no longer produces hormones. All it does is convert light to sugar. If you remove an old leaf, it has no particular effect on the surrounding leaves, branches and buds - no hormones. You just lose the leaf production area, and if that's buried in the shade, you're not losing much. And since the byproduct of phosynthesis is glucose, and glucose is distributed throughout the plant, you can light the plant on one side and that'll feed the other side.

Yes? No?
