Wood chemical composition in species of Cactaceae: the relationship between lignification and stem morphology. [PDF]

open access: yesPLoS ONE, 2015
In Cactaceae, wood anatomy is related to stem morphology in terms of the conferred support. In species of cacti with dimorphic wood, a unique process occurs in which the cambium stops producing wide-band tracheids (WBTs) and produces fibers; this is ...
