Title: Mechanical properties of stemwood and limbwood of seed orchard loblolly pine

Author: McAlister, R. H.; Powers, H. R.; Pepper, W. D.;

Date: 2000

Publication Series: Miscellaneous Publication

Description: Tests were made on micro-bending specimens prepared from stem and limb sections of 11 rust-resistant loblolly pines from a central Georgia seed orchard. A fair correlation (|r| = 0.45 to 0.55) emerged between the stemwood and limbwood modulus of elasticity (MOE) and stemwood and limbwood modulus ofrupture (MOR) values. An excellent correlation (|r| = 0.8 to 0.9) appeared between the MOE and MOR of the stemwood and also between the MOE and MOR ofthe limbwood. Including specimen specific gravity (SG) did not increase the prediction power of the regression equation. Further work on at least 30 forest-grown trees is planned.
