Tree Segmentation

[treeseer]

I found 'genetic mosaic' challenging; the phrase rhymes, but the meaning escapes me.

 

Conceptually frenetic; not at all prosaic.

 

Certainly kinetic, but is it a 'mosaic'?

 

Not a montage, assortment or medley,

 

It's organically growing, readily, steadily.

 

I'll stop now, 'fore Tony has a cow...

Very good! I'll try and make my questions in sonnet form next time.

And you're sure to do a better job.

Tony, now you've confused me. Why do you suggest that these trees are mosaics rather than grown from a single seed? Separate vascular structures that all share the same common origin/genetics was what I thought was being discussed.

 

Meristematic tissue can mutate as it differentiates to become genetically distinct from its parent/neighbour tissue. So the buds on a twig can be subtley different from each other - if those buds go on to form twigs and then branches, then parts of the tree may respond differently to environmental adaptive forces (light regimes, pests, etc). The parts of the tree can be likened to the stones in a mosaic...

I see your couplets and raise you a haiku;

 

A single bud forms

With meristem mutated

A new path begins

Hoo boy ya got me there! I gotta fold for now; not sure how relevant this slight mutation is to the segmentation/column-forming process, but it is worth thinking about!

[woodyguy]

Ok now I get what you mean. I think biologically you are referring to mutation rather than mosaicism (where the cells with different genetics are intermingled with each other within each structure). But yours is more poetic.

I like this thread; it gives me hope. I know someone, for whom a tree isn't worth left standing, if it's not going to make a foreseeable monetary crop and I find that depressing.
