“…The Klason lignin was determined according to the TAPPI Standard T‐222 om‐02 method, which has been used in other studies. [ ][ ][ ] To 0.3 g of the extractive‐free wood, a solution (3 mL) of 72% sulfuric acid in water was added, kept at 18 °C for 2 h and stirred every 30 min. With this procedure, the cellulose and hemicelluloses of the sample hydrolyze.…”

“…This difference might be because in the two studies, different individuals from different localities were analyzed, and the results showed interspecific variation. Other species with fibrous wood or with abundant tracheids have similar behavior …”

“…Based on the results of PCA, although marked differences were observed across the fibrous, non‐fibrous and dimorphic species due to the Klason lignin percentage, variation also occurred among species of the same genus. This was the case for Coryphantha , Mammillaria , and Echinocereus ( Figure ), which was primarily due to the differences in the type of wood and the different proportions and types of thickening of the secondary walls of WBTs, Vs and F. The variation among species of the same genus is consistent with that described by Pettersen , Seegmiller et al ., Escamilla‐Treviño , and Wahab et al . in genera of other taxonomic groups ( Appendix S1).…”

The aims of this study were to determine the wood chemical composition of 25 species of Cactaceae and to relate the composition to their anatomical diversity. The hypothesis was that wood chemical components differ in relationship to their wood features. The results showed significant differences in wood chemical compounds across species and genera (P < 0.05). Pereskia had the highest percentage of lignin, whereas species of Coryphantha had the lowest; extractive compounds in water were highest for Echinocereus, Mammillaria, and Opuntia. Principal component analysis showed that lignin proportion separated the fibrous, dimorphic, and non-fibrous groups; additionally, the differences within each type of wood occurred because of the lignification of the vascular tissue and the type of wall thickening. Compared with other groups of species, the Cactaceae species with fibrous and dimorphic wood had a higher lignin percentage than did gymnosperms and Acer species. Lignin may confer special rigidity to tracheary elements to withstand desiccation without damage during adverse climatic conditions.
