- Sampling sufficiency of the anatomical characteristics of Brazilian hardwood using the resampling method André Luiz Missio Fábio Mariano Bayer Darci Alberto Gatto Pedro Henrique Gonzalez de Cademartori Ingeniería Bootstrap mature wood sample size juvenile wood Luehea divaricata Sampling sufficiency of the anatomical characteristics of fibres from Luehea divaricata wood was investigated through the bootstrap resampling method. Sampling sufficiency of fibre length, fibre diameter, lumen diameter and fibre wall thickness were determined. Three scenarios of sampling sufficiency evaluation were used: general, segregation between juvenile and mature wood, and accumulation throughout the life of the tree. The segregation of juvenile and mature wood showed that sampling sufficiency in juvenile wood was higher than in mature wood, up to three times for the fibre length. In general, results indicated higher values than suggested in specific standards and by other authors. Therefore, resampling bootstrap methodology, even though underused in forestry research, is an alternative for new studies, as it does not have restrictive hypotheses such as data normality. 2014 artículo científico 1806-2563 https://www.redalyc.org/articulo.oa?id=303231059005 en http://www.redalyc.org/revista.oa?id=3032 Acta Scientiarum.
