ATRIBUTOS HISTOLÓGICOS RELACIONADOS CON DIGESTIBILIDAD EN Bouteloua curtipendula (MICHX.) TORR. DE MÉXICO

Abstract: Pasto banderita (Bouteloua curtipendula (Michx.) Torr.) es un forraje C4 de gran diversidad genética, adaptado a regiones áridas y semiáridas del norte de México y sur de los E.E.U.U. En este estudio se evaluaron los atributos histológicos asociados con digestibilidad y lignificación en 30 genotipos de B. curtipendula de México para conocer su potencial forrajero. Con un diseño completamente al azar se muestrearon hojas verdes maduras a los 65 d de rebrote de una colección viva. El tejido foliar se fijó y proc… Show more

“…For the three grass species studied, the older the plant, the lower the CP, TDN, RFV, ME, NE l , NE m , and NE g (Table 2). In addition, NDF and ADF increased as the plants grew older, as reported by Bernal-Flores et al (2017). The CP content in buffel grass at each cutting date was higher than in rhodes and blue grama (P0.001).…”

“…The forage pastures quality is given by the constitution of the epidermal tissues; therefore, in C 4 species such as the grasses included in this study, the mesophyll, phloem, epidermis, parenchyma, and bundle sheath degrade slowly or partially (Guevara and Ramia, 2007). Therefore, in the case of the side oats grama (B. curtipendula), according to Bernal-Flores et al (2017), the digestibility of the phloem and mesophyll is high and 70% of the chloroplast protein is concentrated in the latter. Meanwhile, xylem and sclerenchyma are high in lignin, especially in the primary veins, which consequently entails partial degradation.…”

“…The components in the cell wall and cell content can vary according to the geographic area, phenological stage of the plant, and cell tissue analyzed. For example, Bernal-Flores et al (2017) report variability in lignin concentration by studying various tissues of 30 genotypes of Banderilla grass [Bouteloua curtipendula (Michx.) Torr.]…”
