This project aims to reveal how specific water-stress thresholds damage the leaves of Australian crop and forest species during drought. Water stress affects agricultural productivity and plant survival in drought-prone regions such as Australia. Using optical and X-ray techniques, this project seeks to visualise and quantify the dynamic processes of damage and repair in leaves under stress. Anticipated outputs include a practical basis to predict drought-induced canopy death; identification of threats to ecologically sensitive plants; and selection and screening tools to improve the drought resilience of agriculturally important crop species.

该项目旨在揭示特定的水分胁迫阈值如何在干旱期间损害澳大利亚作物和森林物种的叶子。在澳大利亚等干旱易发地区，缺水影响农业生产力和植物生存。利用光学和X射线技术，该项目旨在可视化和量化胁迫下叶片损伤和修复的动态过程。预期产出包括：为预测干旱引起的林冠死亡提供实用基础;查明对生态敏感植物的威胁;提高重要农业作物品种抗旱能力的选择和筛选工具。
