Drought significantly impacts the growth and yield of Chinese chestnut trees, specifically in the Yan-shan Mountains.
A 22-day drought simulation revealed that water content in the trees' roots, stems, and leaves decreased substantially while proline and malondialdehyde levels increased, indicating stress responses.
While drought stress hindered photosynthetic performance, the chestnut seedlings showed an ability to adapt by enhancing their carbon and nitrogen metabolism, which could guide future drought-resistant breeding efforts.
