| Crynodeb: | Correlation between chemical compounds and mechanical response in culms of two different ages of Guadua angustifolia KunthWet chemical analysis was used to determine carbohydrate structural contents, as well as ash and extractive contents on four GuaduaAngustifolia 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 testingmachine following ASTM D143 standard method in order to determine modulus of rupture (MOR). Finally, a correlation between contentsof chemical compounds and bending behavior (MOR modulus) was carried out with SPSS Statistical Package, version 7.0, obtainingPearson’s coefficient correlation and showing the relationship between soluble fibers and bending response for mature Guadua culms.
