Tutorial: Fitting the CO2 Response Curve in A-Ci Curve Fitting Tools


Delivered on: 23 May 2024


This video demonstrates how to fit the CO2 Response Curve (A-Ci curve) using the fitting tools. The demonstration includes:


  • A-Ci Curve Fitting Tools: We'll demonstrate how to download and utilise the A-Ci Curve fitting tools from landflux.org to analyze your data.


  • Troubleshooting Errors: Learn how to troubleshoot common errors that may arise when using the A-Ci Curve fitting tools.


  • Data Extraction and Conversion: We'll guide you through extracting key parameters from raw data and converting them into the appropriate units for the fitting tools.


  • Fitting A-Ci Curves: Master the process of fitting your data to the A-Ci curve model to obtain valuable photosynthetic parameters.


  • Interpreting CO2 Response Curves: We'll discuss the theoretical basis of CO2 response curves and how to interpret the extracted parameters.


  • Key Variables: We'll explain the significance of variables like Ca (ambient CO2), Ci (intercellular CO2), and Cc (chloroplastic CO2) in understanding photosynthesis.


  • Experimental Design and Data Collection: Gain insights into designing effective experiments and determining the optimal number of measurements for reliable A-Ci curves.
