“…It is also possible define from the Figure 2 that Macana variety has a higher insoluble fiber content in each bamboo culm section than Rayada Amarilla; however, as a whole, insoluble fiber content is higher in Guadua angustifolia Rayada Amarilla as was shown in Table 1. As was found by Wang et al (2011) and Sanchez-Echeverri et al (2014) the mechanical response in bamboo culms is a correlation between both fibers; therefore, according with that results Macana culms are more appropriated for structural applications while Rayada Amarilla could be thinking for other applications such cellulose and pulp production.…”

“…In the last three decades, bamboo has increased in importance around the world because of its mechanical, esthetic, and ecological properties, making it versatile for many applications. Moreover, the wide variety in appearance and chemical composition are some of the reasons why bamboo is more attractive, even than wood, for several purposes (SANCHEZ-ECHEVERRI et al, 2014). Not only the uses of bamboo as structural material are studied; some studies have shown the importance of bamboo leaves as pozzolanic materials to remove Cadmium I (Cd(I)) ions from aqueous solution (VILLAR-COCIÑA et al, 2011;PANDEY et al, 2015).…”

O estudo sobre os materiais para obter fibras naturais tem tido grande importância nas últimas décadas devido às características excepcionais que essas fibras oferecem, as quais as convertem em uma alternativa interessante para substituir as fibras sintéticas em diferentes aplicações. O Bambu tem alta disponibilidade em várias regiões do mundo, devido à capacidade de adaptação e de crescimento em diferentes áreas. Apesar de as fibras de bambu estarem sendo altamente aplicadas, sua organização microestrutural dentro das hastes não tem sido estudada amplamente. O objetivo desta pesquisa está baseado no desenvolvimento e estudo das características e distribuição das fibras dentro do colmo no bambu nativo colombiano Guadua angustifolia Kunth. Neste estudo foram consideradas duas variedades de Guadua: Guadua angustifolia Kunth Rayada Amarilla e Guadua angustifolia Kunth Macana. As Guaduas foram analisadas por microscopia eletrônica de varredura, esta técnica é usada para observar a morfologia da fibra de Guadua e a sua variação através do colmo. Difração de raios X é usada para observar variação dos compostos através do colmo. Finalmente, a metodologia da “Association Official Agricultural Chemist – 2000” (AOAC-2000) é usada para obter informação quantitativa do conteúdo de fibra não solúvel. Os resultados indicaram que a distribuição de fibras não solúveis não é homogênea entre as camadas internas e externas da haste do bambu, isso aumenta na direção radial da parede interna até a parede externa; os padrões de difração de raios X mostram que a celulose presente no colmo tem uma preferência de ligação cristalina relacionada à direção do crescimento da planta. A combinação da análise de microscopia eletrônica de varredura e a difração de raios X oferecem informações importantes sobre a distribuição e a morfologia dentro do colmo dos componentes do Bambu.

“…Moreover, forages with higher contents of crude protein, N-free extract (total carbohydrates excluding the crude fiber), and ether extract and low amounts of crude fiber are also preliminary indications that help to evaluate the forage quality (Mandal and Gautam 2012). -Echeverri et al 2014). In the present study, the content of CP in culms was lower than leaves.…”

“…Other minor components like mannan, arabinan, and galactan were also detected as shown in Figure 7d. Previous studies [110,111] have shown that the biomechanical properties of the biomass tissues are highly correlated with composition. A significant reduction in lignin and glucan in RG could be due to reduced lignin and cellulose deposition in the sclerenchyma and vascular bundle cells [112].…”

Stalk lodging contributes to significant crop yield losses. Therefore, understanding the biomechanical strength and structural rigidity of grain stalks can contribute to improving stalk lodging resistance in crops. From the structural constituents of the stalk, the rind provides the principal structure, supporting cells against tension and bending loads. In this work, the biomechanical and viscoelastic behavior of the rind from the internodes of two sweet sorghum varieties (Della and REDforGREEN (RG)), grown in two different growing seasons, were evaluated by three-point micro-bending tests using a dynamic mechanical analyzer (DMA). In addition, the chemical composition of rinds and the microfibril angle (MFA) of the cell wall were determined using XRD. The results revealed that the biomechanical behavior of Della varieties was stiffer and more resistant to loads than that of RG varieties. Two features of the rind biomechanical properties, flexural modulus (FM) and flexural strength (FS), showed a significant reduction for RG. Particularly, a reduction in FS of 16–37% and in FM of 22–41% were detected for RG1. Changes in the stalks’ rind biomechanical properties were attributed to cell wall components. Total lignin and glucan/cellulose contents were positively correlated with the FM and FS of the rind. Subsequently, an increase in the two cell wall components drove an increase in stiffness. Furthermore, the MFA of the rind was also found to influence the rind strength.
