Plume poppy – Macleaya cordata (Willd.) R.Br., Papaveraceae family is a perennial herbaceous species with medicinal, melliferous, ornamental and energy biomass utility. The harvested stem biomass from Macleaya cordata can be used as feedstock for the production of solid fuel – briquettes and pellets. The objective of this research was to evaluate some agrobiological peculiarities and quality indices of biomass of Macleaya cordata 'Mihaela’ grown in experimental field of the NBGI MSU Chişinău, Republic of Moldova. At the end of the flowering period, Macleaya cordata shoots reach 303-320 cm in height, with 35.8-38.2% leaf share. The content of alkaloids in Macleaya cordata leaves was: 7.36-8.12 mg/g sanguinarine, 5.91-6.82 mg/g chelerythrine and 0.659-0.757 mg/g fagaridine. It has been determined that the stem dry matter productivity of Macleaya cordata harvested in August was 1.19-1.40 kg/m2, but – of plants harvested in November – 1.67-1.79 kg/m2. The comparative analysis of cell wall components revealed that Macleaya cordata substrate contained 406-503g/kg cellulose, 212-243 g/kg hemicellulose and 91-104 g/kg acid detergent lignin, the estimated theoretical ethanol yield from cell wall carbohydrates averaged 448.7-541.8 L/t in Macleaya cordata substrates.
