An efficient method to reduce grain angle influence on NIR spectra for predicting extractives content from heartwood stem cores of Toona. Sinensis
NIR spectra heartwood stem cores Toona. Sinensis grain angle
2023/6/5
A fast, reliable and non-destructive method is needed to qualify the extractives content (EC) in heartwood of T. sinensis cores in the breeding program for studying the genetic effect on EC. However, ...
Adaptive k-tree sample plot for the estimation of stem density: An empirical approach
plotless sampling distance sampling bias efficiency forest sampling
2018/3/6
Available budgets for the inventory of non-commercial woodlands are small. Therefore, there has been increased
interest in using distance methods, such as k-tree sampling, which are faster than fixed...
