Classification Toona Sinensis Young Leaves
2023/6/2
Rapid and accurate distinction between young and old leaves of Toona sinensis in the wild is of great significance to the selection of T. sinensis varieties and the evaluation of relative yield. In th...
Comparison of partial least squares-discriminant analysis, support vector machines and deep neural networks for spectrometric classification of seed vigour in a broad range of tree species
least squares-discriminant analysis spectrometric classification seed tree species
2023/6/5
Seed vigour significantly influences the seed production and plant regeneration performance. The capability of NIR spectroscopy to identify seed vigour across multiple tree species rapidly and cost-ef...

Site classification vs. wood production: a case study based on Silver fir growth dynamics in the Western Carpathians
Western Carpathians site classification production potential Silver fir growth model
2015/3/27
We analysed wood production on an example of Silver fir growth ability within site units defined in the site classification that is currently used in the Western Carpathians. It has arisen as a very i...
Different approaches to the classification of vertical structure in homogeneous and heterogeneous forests
height variability forest status survey NFI structural classification
2015/3/19
The paper shows difficulties in the evaluation of the forest status when considering forests with different height structure (uneven-aged forests). It is the main problem in categorizing such forests....
Uniqueness of limestone soil-forming substrate in the forest ecosystem classification
limestone pedology micromorphology
2015/3/6
The uniqueness of limestone soil-forming substrate was assessed with respect to the classification of forest ecosystems. 50 soil profiles from the Bohemian Karst were studied and the results were conf...
