AB [EN] Background: Besides the use of maize grain as food and feed, maize stover can be a profitable by-product for cellulosicethanol production, whereas the whole plant can be used for silage production. However, yield is reduced bypest damages, stem corn borers being one of the most important yield constraints. Overall, cell wall composition iskey in determining the quality of maize biomass, as well as pest resistance. This study aims to evaluate the compositionof the four cell wall fractions (cellulose, hemicellulose, lignin and hydroxycinnamates) in diverse maize genotypesand to understand how this composition influences the resistance to pests, ethanol capacity and digestibility.Results: The following results can be highlighted: (i) pests’ resistant materials may show cell walls with low p-coumaricacid and low hemicellulose content; (ii) inbred lines showing cell walls with high cellulose content and highdiferulate cross-linking may present higher performance for ethanol production; (iii) and inbreds with enhanceddigestibility may have cell walls poor in neutral detergent fibre and diferulates, combined with a lignin polymer compositionricher in G subunits.Conclusions: Results evidence that there is no maize cell wall ideotype among the tested for optimal performancefor various uses, and maize plants should be specifically bred for each particular application.
