Red, Green & Blue: Misconceptions About the Photosynthetic Efficacy of Different Light Colors | 07.23.20
Presented by Marc van Iersel, PhD
Because of the relatively low leaf absorptance of green light, it is commonly believed to be inefficient in driving photosynthesis. Dr. Marc van Iersel, from the University of Georgia, will discuss how A/Ci and light-response curves were used to develop a more nuanced understanding of the interactive effects of light intensity and color with regard to photosynthesis.
About Dr. van Iersel
Dr. Marc van Iersel has been with the University of Georgia’s Department of Horticulture since 1995, where he now holds the Dooley professorship.
His research focuses on cost-effective supplemental lighting technologies in greenhouses and vertical farms.
He is the director of project LAMP, a $5M, US-based research project that brings together plant scientists, engineers, and economists to develop profitable supplemental lighting strategies.
In 2017, he co-founded Candidus, Inc. to help bring novel lighting strategies to the greenhouse industry.
Dr. van Iersel has published 130+ scientific papers and has given invited lectures about his research around the world, including in Italy, Spain, Taiwan, Kenya, Canada, Chile, and Brazil.
What, Why & How: A/Ci? | 06.24.20
Presented by James Bunce, PhD
Learn the purpose of performing non-steady-state A (Assimilation) vs. CI (Intercellular CO2) curves and how to perform and process them quickly.
About Dr. Bunce
Dr. James Bunce built his first photosynthesis system as a graduate student 48 years ago and has been performing leaf gas exchange measurements, including many A/Ci curves ever since. He recently retired from a 40-year career with the USDA-ARS in Beltsville Maryland as an environmental plant physiologist. His most recent work involves predicting impacts of global change on plant physiology.
Since his retirement, Jim has been working closely with PP Systems assisting in the development of rapid A/Ci analysis with the CIRAS-3. He has recently published two research papers utilizing that technology: Three Methods of Estimating Mesophyll Conductance Agree Regarding its CO2 Sensitivity in the Rubisco-Limited Ci Range and Variation in Responses of Photosynthesis and Apparent Rubisco Kinetics to Temperature in Three Soybean Cultivars.
