気候変動による干ばつがトウモロコシ栽培に与える影響を緩和するため、アーバスキュラー菌根菌（AMF）の接種効果を温室実験で検証。AMF接種により、植物の高さ、生体重、茎径、根乾燥重量が向上し、特に深刻な干ばつ条件下で顕著な改善が見られた。AMFは水制限環境での作物の回復力と生産性を高める有望な戦略である。
English
This study tested arbuscular mycorrhizal fungi (AMF) as a nature-based solution to mitigate drought stress in maize under greenhouse conditions. AMF inoculation improved plant height, fresh weight, stem diameter, and root dry weight, especially under severe drought (30% field capacity). The findings suggest AMF can enhance crop resilience and productivity in water-limited environments, offering a climate adaptation strategy for agriculture.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の農業は水資源の制約や気候変動による干ばつリスクに直面しており、AMFのような自然ベースの解決策は、持続可能な農業生産に貢献する可能性がある。ただし、GX政策や開示制度との直接的な関連は薄い。
In the global GX context
Globally, this research contributes to climate adaptation in agriculture, aligning with nature-based solutions and sustainable land management. It provides empirical evidence that can inform climate-resilient agricultural practices, though it does not directly address corporate disclosure or transition finance.

📄 Abstract（原文）
In the face of climate change, drought stress represents a critical challenge to the sustainability of maize (Zea mays L.) cultivation. This study explored the potential of Arbuscular Mycorrhizal Fungi (AMF) to enhance maize tolerance to drought. The experiment was conducted in a glass greenhouse of the Soil Fertilizer and Water Resources Central Research Institute, Ankara, employing a factorial design with five AMF treatments under three water stress levels (70%, 50%, and 30% of field capacity). Maize plants inoculated with AMF demonstrated notable improvements in growth parameters under drought conditions. At 70% field capacity, the AMF treatment with Rhizophagus intraradices (M3) significantly increased plant height (PH) by up to 104.2 cm and fresh weight (FW) by 35.7 g, compared to control values of 95.7 cm and 27.5 g, respectively. Similarly, at 50% field capacity, AMF treatments sustained higher stem diameter (SD) measurements, with a notable instance being Rhizophagus irregularis (M2) at 5.44 cm, against a control value of 4.74 cm. The resilience of AMF-treated plants was further underlined by the improved root dry weight (RDW) in the face of severe drought stress (30% field capacity), where Glomus iranicum (M5) treatments resulted in RDW of 1.20 g compared to 0.73 g in non-AMF-treated plants. These findings substantiate the hypothesis that mycorrhizal symbiosis can significantly mitigate the effects of drought stress on maize, suggesting a viable strategy to enhance crop resilience and productivity in water-limited environments.
