RESUMO
This article describes a dataset of images depicting the monthly wood formation of Anthocephalus macrophyllus throughout the year. The images were obtained from cross-sectional stem sections of the tree starting from January, February, March, April, May, June, July, August, September, October, November, and December 2021. The image capture process was conducted at the Nano Imaging-Advanced Research Laboratory, IPB University, using the Keyence VHX-7000 digital microscope with a magnification of 20x. Each image was in JPG format with dimensions of 2880 × 2160, providing a comprehensive overview of wood formation each month. The pinning process resulted in distinct marks in both the bark and wood. In the bark, damage and healing due to injuries are clearly visible. Similarly, in the wood section, the wood formation area was clearly evident. The dataset on wood formation based on the application of pinning provides an interesting image analysis for observing wood formation in tropical regions. The data generated from different locations and climates can serve as comparative data for observing wood formation in other species.
