Dose any one know why Corylus avellana 'Contorta' grows the way it dose?

[Dilz]

yup genetics, like apple varieties, you cant grow em by seed but by cuttings.

[toprotter]

Or graffs on hazel root stock

Auxins, i think thats how you spell it.

[Tony Croft aka hamadryad]

Asking the right questions is the route to knowledge, so you should go far

Abstract

In plants, directional cell expansion greatly contributes to the final shape of mature cells, and thus to organ architecture. A particularly interesting mode of cell expansion is helical growth in which the growth axis is continuously tilted either to the right or to the left as the cell grows. Fixed handedness of helical growth raises fundamental questions on the possible origin of left-right asymmetry. Twisting mutants of Arabidopsis thaliana offer unique opportunities to study the cellular basis of helical growth. Most of the twisting mutants with fixed handedness have been shown to have defects in microtubule functions, whereas mutants that twist in non-fixed directions appear to be defective in auxin response or transport. Good correlations have been found between the tilted growth direction and alignment of cortical microtubule arrays in twisting mutants with compromised microtubule functions. The present challenge is to understand how particular array patterns are organized during progression of the interphase in rapidly expanding cells. Molecular and cell biological studies on twisting mutants will lead to better understanding on how wild-type plant cells utilize the microtubule cytoskeleton to initiate and rigorously maintain straight growth.

Interesting. Always wondered but never thought to look, thought it would be genetic...

Thats what i said Tony, Auxins, i am a man of few words but you put it very well, i must try and look out my old notes.

I know you did fella, and I didnt have a scooby doo:thumbup1:

 

Im just getting good at sourcing stuff!

[Amelanchier]

Ever looked to see which way they twist?

no, why you ask?

As Hama said. The reason you get straight growth from the roots is because the root stock is standard Hazel with the contorta grafted on to it, and the root stock can throw up suckers if it is under stress.
