     in this study the impact of senescence and harvest time in miscanthus on the quality of fast pyrolysis liquid (bio-oil) was investigated. bio-oil was produced using a 1 kg h−1 fast pyrolysis reactor to obtain a quantity of bio-oil comparable with existing industrial reactors. bio-oil stability was measured using viscosity, water content, ph and heating value changes under specific conditions. plant developmental characteristics were significantly different (p ⩽ 0.05) between all harvest points. the stage of crop senescence was correlated with nutrient remobilisation (n, p, k; r2 = 0.9043, r2 = 0.9920,r2 = 0.9977 respectively) and affected bio-oil quality. harvest time and senescence impacted bio-oil quality and stability. for fast pyrolysis processing of miscanthus, the harvest time of miscanthus can be extended to cover a wider harvest window whilst still maintaining bio-oil quality but this may impact mineral depletion in, and long term sustainability of, the crop unless these minerals can be recycled.
