The scope of this study was to evaluate the importance of cytotype and cutting system on the pyrolytic production of semi/volatile compounds that ultimately ends up into bio-oil. The approach was based on the analysis of pyrolysis products by a microscale pyrolysis apparatus. An upland (trailblazer) and a lowland cytotype (Alamo) under one- (winter) or two-cut (summer plus winter re-growth) systems were compared. Pyrolysis experiments were conducted by means of a platinum filament analytical pyrolyser at 700 °C and evolved products were analysed by GC-MS and quantified by internal calibration. Yields (by weight relative to pyrolysed biomass amount) were determined on a suite of pyrolysis products representative of chemical families, namely organic acids, aldehydes, lignin phenols and C5-C6 cyclic carbohydrate derivatives.
