“…Results from this work indicate the existence of a positive but low phenotypic and genetic correlation between growth and spiral grain (0.24 and 0.15 respectively), indicating that grain inclination tend to be maintained in fast growing trees. Similar findings were reported for P. abies by Costa e Silva et al (2000) and Hallingback et al (2008). Lower but inconsistent correlations were obtained for Pinus caribaea (Harding et al, 1991), Pinus sylvestris (Hannrup et al, 2003) and P. abies (Hansen and Roulund, 1997;Hannrup et al, 2003).…”

“…This excludes the possibility of accounting for genotype-by-environment (G × E) interactions and heritabilities estimated in this study could therefore be biased upwards. Nonetheless, for wood density, MoE and grain angle, such biases are still expected to be minor because other studies of Norway spruce have indicated only weak G × E-interactions (r a across sites estimated at 0.74 or above, Hallingbäck et al 2008;Chen et al 2014). The foremost complication, however, was the difference in sampling height between the wood trait assessments made in the field at breast height (1.3 m) and the radial profiles extracted from top of the butt log (at 3.3 m).…”

In breeding Norway spruce, selection for improved growth and survival is performed at age 10-15 years in order to optimize genetic gain per year. We investigated whether a selection based on wood traits such as density and grain angle, measured under bark in the field at the same age would be informative enough with respect to structural quality traits of sawn boards. To achieve this objective, a sawing study was conducted on the butt logs of 401 trees from a 34-year-old Norway spruce progeny trial situated in southern Sweden. Stem discs were excised from the top of the logs and radial profile data of grain angle, and wood density was recorded for specific annual rings. The sawn and dried boards were assessed for structural traits such as twist, board density, bending stiffness (static modulus of elasticity, sMoE) and bending strength (modulus of rupture, MoR). Additive genetic correlations (r a) between single annual ring density measurements and board density, sMoE and MoR were consistently strong (r a > 0.7) for annual rings 5-13. Genetic correlations of similar magnitude between grain angle and board twist were estimated for all investigated annual rings (from 2 to around 26 under bark). Consequently, it was found that indirect selection for wood density and grain angle at the tree age 10-16 years would result in more genetic gain per year than selection at later ages. This makes it feasible to perform simultaneous selection of progeny in the field for both growth and wood traits at similar ages.

“…The results indicated that the heritability value in the pilodyn penetration and the wood physical properties are greater than the heritability of growth (height), but did not differ from the heritability of diameter (Hallingbäck et al 2008;Wu et al 2008;Chen et al 2014;Hong et al 2014;Hayatgheibi et al 2019).…”

Abstract. Anna N, Supriyanto, Karlinasari L, Sudrajat DJ, Siregar IZ. 2020. The growth, pilodyn penetration, and wood properties of 12 Neolamarckia cadamba provenances at 42 months old. Biodiversitas 21: 1091-1100. Jabon (Neolamarckia cadamba (Roxb) Bosser) is a potential tree species for the development of plantation forests and community forests to supply timber demands. Information on the growth characteristics and wood properties of N. cadamba is important for the present and future development, yet. Those data is not available. This study aimed to assess the variations on growth (height, diameter), pilodyn (Pilodyn®) penetration, and physical properties of wood from core sample; and characterize the wood properties of 12 N. cadamba provenances at Parung Panjang, Bogor. The assessment of growth characteristics, pilodyn penetration, and physical properties of wood from core sample was carried out through census (1030 trees) on all provenance (using non-destructive method). The wood properties analysis was carried out using destructive method to one sample for each of the 12 N. cadamba provenances. Growth characteristics observed were the height (numerical scale pole), diameter (calipers), and pilodyn penetration. Meanwhile, the wood properties consisted of wood density, specific gravity, moisture content, fiber length (light microscope), MFA (x-ray diffraction), MOE, and MOR. The results showed that the correlation between the height and moisture content with pilodyn penetration was weak and positive, while the correlation between diameter, wood density, and specific gravity was weak and negative. The result of non-destructive test showed that Gowa provenance is superior. The results of destructive tests to investigate the wood properties of the twelve provenances showed that Batu Licin provenance is superior in terms of specific gravity and MOE, while Gowa provenance is superior in terms of MOR and fiber length. The results of the wood properties (i.e. density, specific gravity, moisture content, MOE, MOR, MFA, and fiber length) of the 12 N. cadamba provenances showed that the woods can be potentially used as non-structural materials only.
