Thanks, but about Larix sibirica, I'm looking for Pinus sibirica.

ah, sorry, did not read carefully!

Everything is pretty old.  You need to do a full literature search.  Not much is on the internet.  There are other citations regarding properties of the branch wood and the seeds also.

Try this citation. 

The relation of the physical and mechanical properties of Pinus sibirica wood to growth conditions.

Isaeval, L.N.

Svojstva drevesiny, ee zascita, i novye drevesnye materialy, 1966, 20-9

Or this one:

Vipper, P.B.

Trudy instituta lesa. akademiya nauk sssr, 1953, 9, 415-418

or this one:

Effect of moisture content on the mechanical properties of Pinus sibirica wood.

Makarenkov, V.N.

 Lesnoi zhurnal, arkhangel'sk, 1961, 4 (1), 84-8

or this:

Babintseva, R.M.; Isaeva, L.N.; Nekrasova, A.A.

Lesnoe khozyaistvo, 1989 ( 1), 30-33

or this:

Very Thanks for your message Julie,

I'm looking for basic properties of the wood itself.

Resistance to compression, tensile, cleavage, and wood density.

thanks again for literature.

Hello Aleksandra,

I have found some data about physical and mechanical properties of Siberian yellow pine (Pinus sibirica Du Tour) in the book "Science of wood" by Wanin (Wanin S., 1953: Nauka o drewnie. Wydawnictwo Rolnicze i Leśne. Warszawa):

- typical width of annual rings 1-2 mm,

- contribution of late wood 25%,

- air-dry wood density (moisture content about 15%) 440 kg/m2

- radial shrinkage 3,7%,

- tangential srinkage 8,2%,

- volume shrinkage 14,0%

- compressive strength parallel to grain 37 MPa,

- static bending strength (three point bending) 63 MPa,

- shear strength 5,9 MPa.

The Autor described also the anatomy (micro- and macrostructure) of Siberian yellow pine wood (the Polish name "limba syberyjska") in his book. In my opinion the mechanical properties of Siberian yellow pine are similar to properties of Norway spruce wood (Picea abies (L.) Karst.).

I hope that this information will be useful for you.

Thanks  you.
