Effects of radial growth rate on juvenile wood properties of Pinus sylvestris planted in Mongolia

The establishment of forest plantations in boreal zones Mongolia is important for wood production as well carbon dioxide fixation. present study aims to elucidate the juvenile properties (basic density, modulus elasticity [MOE], rupture [MOR], and compressive strength parallel grain) plantation-grown Pinus sylvestris promote plantations. In addition, effect radial growth rate on was also evaluated using a linear mixed-effects model. phase, were increased from pith bark side based results model selections. Up 20th annual ring pith, estimated mean values basic MOE, MOR, 0.40 g/cm3, 5.35 GPa, 65.1 MPa, 28.4 respectively. Variance component ratios categories low properties, with exception suggesting that did not affect phase this species growing Mongolia. Based obtained study, we have concluded although density faster category yielded relatively lower values, appropriate promotion during initial stage P. trees planted exerted no negative impact properties.
