Genetic architecture behind developmental and seasonal control of tree growth and wood properties in Norway spruce [PDF]

Frontiers in Plant Science, 2022
Genetic control of tree growth and wood formation varies depending on the age of the tree and the time of the year. Single-locus, multi-locus, and multi-trait genome-wide association studies (GWAS) were conducted on 34 growth and wood property traits in ...

Heat transfer, physiological responses, and subjective perceptions during short contact time with wood or other materials

Journal of Wood Science, 2021
This study investigates the physiological responses and subjective perceptions of touching wood. In particular, it focuses on their respective relationships with the amount of heat transfer across the hand–material interface during contact.

Anatomical characterization and technological properties of Pterogyne nitens wood, a very interesting species of the Brazilian Caatinga biome

Scientific Reports, 2021
Pterogyne nitens is commonly known in northeastern Brazil as a lesser-known fast-growing species in the Caatinga biome, which is a difficult place for tree development due to the low natural fertility soils and low availability of water.

Estimation of finite population mean in two-phase sampling with known coefficient of variation of an auxiliary character

Statistica, 2013
In this paper a double (or two-phase) sampling version of (Singh and Tailor, 2005) estimator has been suggested along with its properties under large sample approximation. It is shown that the estimator due to (Kawathekar and Ajgaonkar, 1984) is a member
