SANCHEZ-ECHEVERRI, Luz Adriana; AITA, Giovanna; ROBERT, Diana  and  RODRIGUEZ GARCIA, Mario Enrique. Correlation between chemical compounds and mechanical response in culms of two different ages of Guadua angustifolia Kunth. Madera bosques [online]. 2014, vol.20, n.2, pp.87-94. ISSN 2448-7597.

Wet chemical analysis was used to determine carbohydrate structural contents, as well as ash and extractive contents on four Guadua Angustifolia Kunth forms (f. Cebolla, f. Macana, f. Rayada Amarilla and f. Castilla) with two different growth ages (young and mature). Soluble and insoluble fiber content was determined by using AOAC 985.29 method. Bending tests were conducted in a universal testing machine following ASTM D143 standard method in order to determine modulus of rupture (MOR). Finally, a correlation between contents of chemical compounds and bending behavior (MOR modulus) was carried out with SPSS Statistical Package, version 7.0, obtaining Pearson's coefficient correlation and showing the relationship between soluble fibers and bending response for mature Guadua culms.

Keywords : bamboo culms; Chemical composition; Fiber Content; Modulus of Rupture; Mechanical properties.
