Quantifying the effect of factors controlling CO assimilation is crucial for understanding plant functions and developing strategies to improve productivity. Methods exist in numerous variants and produce various indicators, such as limitations, contributions, and sensitivity, often causing confusion. Simplifications and common mistakes lead to overrating the importance of diffusion-whether across stomata or the mesophyll. This work develops a consistent set of definitions that integrates all previous methods, offering a generalised framework for quantifying restrictions. Ten worked examples are provided in a free downloadable spreadsheet, demonstrating the simplicity and applicability to a wide range of questions.
量化控制二氧化碳同化的因素的影响对于理解植物功能和制定提高生产力的策略至关重要。现有多种方法变体，会产生各种指标，如限制、贡献和敏感性，常常造成混淆。简化和常见错误导致高估扩散的重要性——无论是跨气孔还是跨叶肉的扩散。这项工作提出了一套统一的定义，整合了以前所有的方法，提供了一个量化限制的通用框架。在一个可免费下载的电子表格中提供了十个实例，展示了该方法对于广泛问题的简单性和适用性。
