Non-destructive and semi-destructive methods for wood grading via assesment of standing trees and logs

Popis výsledku v původním jazyce

The high demand for spruce timber has led to the expansion of Norway spruce monocultures outside its natural ecological area in Central Europe - it results in a wide-range and gradual variation of wood properties. The wood quality plays an important role in timber structure properties thus the individual selection of material is the first important step of traditional carpentry. The selection of trees in the forest should be emphasized to reach a balance between properties for better processing and material properties. Therefore, simple and reliable methods for in-situ assessment of standing trees or logs are searched. The goal of this study is to test standing trees and logs by several methods and to describe relationship between the evaluated material parameters. The trees from a stand in the Czech Republic with optimal ecological conditions for Norway spruce were felled during three seasons, consequently milled to logs and tested by several methods: wood densities, sound velocities, dynamic moduli of elasticity, micro-drilling. The visual assessment was carried out as well. The relationship between properties were statistically tested to determine the reliability of used non-destructive and semi-destructive methods to predict quality and also to describe the significance of harvest period.
