| Outline of Final Research Achievements |
The variations of wood properties are affected by both genetic and environmental factors. There are few reports examining the effects of the environmental factors on the wood properties. This study investigated the effects of the soil moisture conditions on wood properties in four domestic species. The sample trees were harvested from valley plot and ridge plot, where the soil moisture content was clearly different.
The growth traits showed significantly higher values in the valley plot than the ridge plot in both species. The soil moisture content gave different influences on the wood properties at each growth period. We built the statistical model to predict the wood properties at each growth condition. In the future plan, the model will be incorporated into the model for predicting the growth traits and contributes the forest management which can respond flexibly to the demand for the ideal resources having both quantity and quality.
