This video is the first part of a two-part series on using the Li-6400XT and LI-6800 Portable Photosynthesis Systems to measure CO2 response curves and calculate A-Ci curves in plants. In this part, we will focus on the following:
Preparing the Li-6400XT and LI-6800: We will discuss how to prepare the Li-6400XT and LI-6800 for a CO2 response curve measurement, including selecting and cleaning a leaf, setting the environmental conditions, and opening the stomata.
Measuring the CO2 response curve with the Li-6400XT: We will demonstrate how to measure the CO2 response curve of a leaf with the Li-6400XT.
Measuring the CO2 response curve with the LI-6800: We will demonstrate how to measure the CO2 response curve of a leaf with the LI-6800.
*Bonus: Measuring Light Spectrum using LI-180 Spectrometer
