Effect of the drying condition on the strength properties of Japanese larch board after vacuum heat treatment

Drying Technology, 2023
This study aimed to investigate the effect of drying conditions on the strength properties of larch boards after vacuum heat treatment, using leftover boards from a previous study that were dried by four methods: conventional kiln drying, high ...

Yields of Japanese Larch Plantations in Pennsylvania

Northern Journal of Applied Forestry, 1989
Abstract Equations to predict site index, merchantable cubic foot volume, basal area, and average tree diameter were developed for unthinned Japanese larch plantations in Pennsylvania. The yield function indicates that a biological rotation of less than 30 years is reasonable on good sites.

Termite feeding deterrent from Japanese larch wood

Bioresource Technology, 2004
Extraction of flavonoids from Japanese larch (Larix leptolepis) wood with water was carried out to prepare a termite feeding deterrent. A two-stage procedure for the extraction was adopted. The first extraction step was performed at ambient temperature (22 degrees C) and the second at elevated temperatures ranging 50-100 degrees C.

Inheritance of wood color, decay resistance, and polyphenol content of heartwood in full-sib families of Japanese larch (Larix kaempferi (Lamb.) Carr.)

Holzforschung, 2022
Japanese larch (Larix kaempferi) is an important plantation species in Japan as well as in Europe. The inheritance of wood color (L*, a* and b*), mass loss by a white-rot fungus (Trametes versicolor) and a brown-rot fungus (Fomitopsis palustris), and ...

Ray properties in the stems of Dahurian larch (Larix gmelinii) and Japanese larch (Larix kaempferi)

IAWA Journal, 2020
Abstract The radial variation of rays within the stems of Dahurian larch and Japanese larch growing in Korea was studied to obtain valuable information to identify the two species and determine wood quality. Uniseriate ray height, fusiform ray height, ray number, ray spacing, and epithelial cell number were investigated by optical microscopy.

Performance of Japanese and Hybrid Larch Progenies in Pennsylvania

Northern Journal of Applied Forestry, 1994
Abstract Two series of larch progeny tests were established at three locations in Pennsylvania in the spring of 1984. The Penn Orchard series contained progenies of 24 "plus-tree" Japanese larch clones growing in a seed orchard in Pennsylvania, two production seedlots of Japanese larch, and two lots of Japanese x European larch hybrids ...

Responses of growth and root dynamics to soil compaction stress in Japanese larch (Larix kaempferi) seedlings

Journal of Forest Research
In forestry, soil compaction can be induced by the use of forest machinery. Although soil compaction may negatively affect the growth of young trees, the effects on tree root dynamics have not yet been clarified in detail.

Effect of combined radio-frequency/vacuum-press drying on the strength properties of Japanese larch board

Drying Technology, 2021
This study was conducted to confirm the effects of combined radio-frequency/vacuum-press (RF/VP) drying on the strength properties of Japanese larch board. The strength properties of board dried at RF/VP was evaluated in comparison with conventional kiln,

Technical note: Polyvinylpyrrolidone (PVP) and proteinase-K improve the efficiency of DNA extraction from Japanese larch wood and PCR success rate.

Forensic Science International, 2021
Illegal distribution of timber disrupts the timber market and depletes forest resources. DNA markers are used to verify the legal distribution of wood.
