Practical guidelines for quantitative wood anatomy on Ginkgo biloba L. [PDF]

open access: yesIAWA Journal, 2022
Summary Ginkgo biloba L., a long-lived relict species, has high ecological, cultural and economic value. Studying the quantitative wood anatomy of G. biloba is important to understand the relationships between their tree-growth and climate change, which could help in the protection of old G. biloba trees.

Wood identification of Dalbergia nigra (CITES Appendix I) using quantitative wood anatomy, principal components analysis and naive Bayes classification [PDF]

open access: yesAnnals of Botany, 2009
Dalbergia nigra is one of the most valuable timber species of its genus, having been traded for over 300 years. Due to over-exploitation it is facing extinction and trade has been banned under CITES Appendix I since 1992. Current methods, primarily comparative wood anatomy, are inadequate for conclusive species identification. This study aims to find a
