Growth and Wood Properties of Sugi（Cryptomeria japonica）Cultivars Planted in the Kyushu Region
sugi cultivar MuPS growth wood property
2009/3/6
This study examined growth and wood properties of sugi (Cryptomeria japonica D. Don) cutting cultivars planted in the Kyushu region. Sixteen cultivars (48 trees) which were identified based on MuPS (...
Influence of Heartwood Extractives on Carbon Content Variations Among Clones in the Heartwood of Sugi（Cryptomeria japonica）
sugi broad-sense heritability extractives carbon content variation
2009/3/6
Heartwood extractives of Sugi (Cryptomeria japonica D. Don) had large variations among clones and high broad-sense heritability. Genetic improvement by selection of clones having large quantities of ...
Effects of Initial Spacing on Growth and Wood Properties of Sugi（Cryptomeria japonica）Cutting Cultivars
Cryptomeria japonica, cutting cultivar, growth, wood property, initial spacing
2009/3/6
To determine the effect of initial spacing on growth and wood properties of sugi (Cryptomeria japonica D. Don) cutting cultivars, six cultivars (Iwao, Hinode, Yamaguchi, Yaichi, Shakain, Yabukuguri) w...
An Application of the Lateral Impact Vibration Method to the Genetic Improvement of Heartwood Moisture Content in Cryptomeria japonica
Cryptomeria japonica heartwood moisture content lateral impact vibration clone
2009/3/6
The lateral impact vibration method is a non-destructive and high through-put method to estimate heartwood moisture content (MC) in living trees. We applied this method to an investigation of 37 clone...
Development of Fundamental Research on Drying of Boxed-heart Square Timber of Sugi（Cryptomeria japonica）
sugi high temperature drying rapid drying checking prevention
2009/3/6
The development of efficient drying methods may be one of the keys for expanding the utilization of domestic sugi (Cryptomeria japonica D. Don) because of the remarkably high drying cost associated w...
Estimation of Annual Increase of Oven-dried Weight of Sugi（Cryptomeria japonica）Trunks
Estimation of biomass Cryptomeria japonica densitometry ring width mean density
2009/3/6
In order to estimate changes of carbon absorption by trees, a method for calculating annual increases of oven-dried weight of individual trunks from width and mean density of annual rings was establi...
Use of the Pilodyn for Estimating Basic Density and Its Applicability to Density-based Classifying of Cryptomeria japonica Green Logs
Pilodyn basic density log classification green condition Cryptomeria japonica
2009/3/6
We used a Pilodyn for estimating basic density in the green condition for the purpose of classifying logs of Cryptomeria japonica D. Don based on their density. The relationships between Pilodyn pene...
The Evaluation of Modulus of Elasticity at an Early Stage of Growth in Sugi (Cryptomeria japonica) Wood Using S2 Microfibril Angle of Latewood Tracheids as a Wood Quality Indicator
Cryptomeria japonica S2 microfibril angle modulus of elasticity
2009/3/4
The objective of this study was to examine the evaluation of modulus of elasticity (MOE) in mature wood using microfibril angle at an early stage of growth. Several wood qualities, such as latewood t...
