Delivered on: 11MAY 2023

This video demonstrates how to measure photosynthesis in three different tropical plant species using the LI-6800 Portable Photosynthesis System. 🌿 We'll take you on a field trip to Universiti Putra Malaysia (UPM) to measure photosynthetic rates in:

• Janda Kaya (Bryophyllum pinnatum): A succulent plant known for its medicinal properties.

• A Tropical Tree Species: Located near the bus stop at the UPM library.

• Bamboo: A fast-growing grass species found around the UPM campus.

What you'll learn:

• Field Techniques: We'll demonstrate how to set up the LI-6800 for field measurements, including selecting suitable leaves, clamping them in the chamber, and configuring environmental parameters.

• Measuring Photosynthetic Rates: See how the LI-6800 measures key photosynthetic parameters, such as assimilation rate, stomatal conductance, and transpiration rate.

• Species Comparisons: We'll compare the photosynthetic rates of the three different plant species, discussing potential reasons for any observed differences.

• Midday Depression: We'll discuss the phenomenon of midday depression, where photosynthetic rates can decline during the hottest part of the day, and its relevance to tropical plants.
