Tiger stripping?

[Bartek]

I have heard many reasons for this curl but I must believe it is genetic.

I asked my friends, who work as foresters. Curly wood is the effect of notorious, sudden changes of temperatures. The vegetation of a tree is in that case unregular "jumping", what is visible in grains (=curly). So curly wood is typical for example for trees, which grown on the edge of the forest
I supose there are other factors too.

Curl in wood is genetic! As early as 1965 German scientists (God bless their attention to detail) discovered that about 40% of the progeny of two curly maple trees would be curly. The amount and amplitude of the curl is also genetically determined. Progeny of very curly trees are more likely to have good curl. Thats why they are often found near each other.

In a sense it is like curly hair in humans -- not all the children of curly haired parents will have curly hair -- so it is somewhat of a recessive gene.

I researched this and wrote a paper on it while in forestry school at VA Tech in 1967. The science has not changed.

That should have said about 60% not 40%.
