本研究は、クロアチアのパグ島で2年間にわたり、エネルギー作物であるジャイアントリード（Arundo donax L.）の地上部バイオマスによる炭素・窒素隔離量を調査した。収穫時期（冬と春）を変えて乾物収量、炭素含有量、窒素含有量を測定した結果、乾物収量は23.7～30.2 t ha-1、炭素含有量は43.2～47.6%、窒素含有量は0.3～0.7%であった。総炭素隔離量は10.9～13.3 t ha-1、窒素隔離量は0.08～0.20 t ha-1であり、収穫時期を春から冬に遅らせることで収量と隔離量が増加することが示された。
English
This study investigated carbon and nitrogen sequestration in above-ground biomass of giant reed (Arundo donax L.), an energy crop, over two years on Pag Island, Croatia. Dry matter yield ranged from 23.7-30.2 t ha-1, carbon content 43.2-47.6%, and nitrogen content 0.3-0.7%. Total sequestered carbon was 10.9-13.3 t ha-1 and nitrogen 0.08-0.20 t ha-1. Delaying harvest from spring to winter increased yield and sequestration. Weather conditions affected carbon content but not other parameters.

日本のGX文脈において
本論文はエネルギー作物による炭素隔離の実証データを提供しており、日本のバイオマスエネルギー政策やカーボンニュートラル目標達成に向けたエネルギー作物の導入検討に参考となる。ただし、研究対象地がクロアチアであり、日本の気候・土壌条件への直接適用には注意が必要。
In the global GX context
This paper provides empirical data on carbon sequestration by giant reed as an energy crop, relevant to global renewable energy strategies and climate mitigation. It contributes to the understanding of biomass potential for carbon capture, which is important for countries considering bioenergy with carbon capture and storage (BECCS) or biomass-based renewable energy targets.

📄 Abstract（原文）
Climate change is one of the biggest challenges today, and some cultivated plants that generate large biomass, known as energy crops, can contribute to its mitigation as they are a significant renewable energy source, which produces their biomass primarily through the sequestration of atmospheric carbon and its incorporation into their biomass. The aim of this work is to determine the amount of carbon and nitrogen sequestered by the above-ground biomass of the energy crop giant reed (Arundo donax L.) at two different harvest times (winter and spring) for two years. The research was conducted during 2019/2020 and 2020/2021 in the natural stand of giant reed on the island of Pag, Croatia. The dry matter yield is in the range of 23.7–30.2 t ha-1, carbon content of 43.2 – 47.6 %, and nitrogen content of 0.3 – 0.7 %. The amount of total sequestered carbon is between 10.9 – 13.3 t ha-1, and nitrogen 0.08 – 0.20 t ha-1. Different weather conditions during different years of research have a significant impact on the carbon content in aboveground biomass, but not on the other parameters studied. Delaying the harvest date from spring to winter, a higher dry matter yield is achieved, and greater amounts of carbon and nitrogen are sequestered. The interaction of different harvest dates and research years has no significant impact on dry matter yield, and the amount of total bound carbon, and a significant impact was determined for the amount of total bound nitrogen and the carbon and nitrogen content in biomass.
