This project aims to resolve a long-standing question about the function of perennial plants: how much of the carbon taken up by photosynthesis is used immediately for growth, and how much is kept in reserve as insurance against future stress? This question is important to our understanding of how plants respond to stresses such as severe drought, and yet lack of data and theoretical modelling currently hampers our ability to answer it. By applying novel data analysis and modelling tools to recent experimental results, the project plans to test hypotheses for how plants allocate carbon between growth and storage in response to stress. Insights from the project may underpin better management of Australia’s vulnerable ecosystems.

这个项目旨在解决一个长期存在的关于多年生植物功能的问题：光合作用吸收的碳中有多少是立即用于生长的，有多少是作为未来压力的保险而保留下来的？这个问题对我们理解植物如何应对严重干旱等压力很重要，但目前缺乏数据和理论模型阻碍了我们回答这个问题的能力。通过将新颖的数据分析和建模工具应用于最近的实验结果，该项目计划测试植物如何在生长和储存之间分配碳以应对压力的假设。从该项目中获得的见解可能有助于更好地管理澳大利亚脆弱的生态系统。
