Abstract
No presente estudo procedeu-se à caracterização tecnológica de alguns híbridos de sisal em comparação com a espécie comum (Agave sisalana Perr.), colhidos no Centro Experimental de Campinas em 1987. A densidade básica (0,172 a 0,249g/cm³) e o teor de matéria seca (16,91 a 24,82%) cresceram da base para a extremidade das folhas de sisal, contrastando com os teores de fibra têxtil (37,71 a 23,43%) e celulósica (21,75 a 14,56%), que decresceram a partir da base das folhas. As fibras celulósicas na base das folhas foram mais curtas; com maior lúmen e menor parede celular. O comprimento das fibras celulósicas do sisal comum (2,63mm) foi maior que os híbridos (1,39 a 2,09mm): estes não apresentaram superioridade tecnológica em relação ao sisal comum.
Some sisal hybrids were studied in comparison to the common sisal (Agave sisalana Perr.) regarding some technological characteristics. The basic density (0.172 to 0.249 g/cm³) and the dry matter (16.91 to 24.82%) increased from the base to top region of sisal leaf. On the other hand, the content of textile fibers decreased from the base to the top of the leaves (37.71 to 23.43). The same trend was observed for cellulosic fibers (21.75 to 14.56%). The cellulosic fibers in the leaf base were shorter, with more lumen and less cell wall. The length of cellulosic fiber on common sisal (2.63mm) was longer than for hybrids (1.39 to 2.09mm). The sisal hybrids didn't show technological superiority over the common sisal.
