Grazing response- A "thorny" issue

[Stephen Blair]

whats really bothering you Tony? the thorns are just something you can focus your rage on, tell uncle Stevie:laugh1:

lmao, just sick and tired of being ripped to ribbons by thorns!

 

really no need for them in a garden after all, and while were bitching about thorns, we should be allowed to use a product known as napalm to bomb cherries that have had roses planted in them 40 odd year ago, have become "unsightly" and now are in need of removal!

Tony, man up.

lol, guess im just starting to use my loaf and looking at alternative methods to relieve the bits of my work that spoil it!

 

if you had my week you would get the point, so to speak:lol:

Here's a tip for removing thorns from your flesh...

Diebetics will often use a special pin/needle to prick the finger prior to taking a blood test. These are available from chemists and such. They are ideal for removing the little blighters from your body. They can be put with a cap on it and then placed into your pocket, or wherever!

Thorns are surely just modified stems so if you remove the apical dominance by nibbling it off you boost the lateral growth production. No nibbles in the centre of the acacia = little lateral growth.

 

Too simples?

 

Not for me. Nature likes simple.

so what were suggesting is that the hormone responsible for apical dominance is the hormone generating extra thorns?

The apical bud produces Auxin which is transported around the tree to supress other growth from becoming overly dominant (the way that Auxin works through the tree helps form the final shape of the tree).

 

I am sure that this is connected to the growth of thorns from pruning cuts as the renewed strong and very tasty apical growth needs protecting from those pesky browsers.

[Tony Croft aka hamadryad]

im aware of auxin, its role in tree form etc, but not sure its responsible for the extra thorn response, more likely this is put in action via hormones caused by damaged cambium, like in the growth response to stresses that cause a reaction to conform to the axiom

Sorry to be too simplistic - you are obviously right. I was suggesting that the loss of apical dominance, through pruning, browsing or other natural occurrences changes the natural harmony and equilibrium as prescribed by axiom and many other lesser known and poorly researched growth hormones. This imbalance, in plants that react strongly such as the Hawthorn, will result in rapid growth of all parts including thorns. Indeed their must be another 'trigger' to grow a thorn and one that can be isolated and removed as per thornless cultivars that still display strong apical dominance characteristics.

 

Thorns have and are part of the trees vascular system. I wonder if, because of this, various toxins and waste products are stored/dumped into the thorns to give them extra bite and greater chance of causing infection? What a wonderful evolutionary twist that would be!

 

Finally, we all see birds fly in and out of hedges at silly speeds - why do we never find dead impaled birds on thorns?
