Mey.) Soják) is a sedge that grows in lakes and marshes in America and some of the Pacific Islands. The hypothesis tested was that the rind and pith of totora stems have different chemical characteristics. A higher ash content on the pith (7.81% vs. 6.36%) may indicate strategies of the plant to reinforce the aerenchyma tissue and clarify the storage mechanism of compounds by bio mineralization. Almost double acid-insoluble lignin content in the rind (16.42% vs. 8.90%) may indicate the potential optimization of industrial procedures such as paper production by using specific tissues of the plant.es-ESTotoraFibras naturalesCelulosaLignina de fibras no maderablesARTÍCULO10.1080/15440478.2018.1541773
