Elgan Moses measures the carbon sequestration rate and transpiration rate in Red Oak leaves using the CI-340 Handheld Photosynthesis System



  • Pigments that have been hiding under chlorophyll since spring explode to the leaf's surface during fall.
  • Fruits and their seeds—the end result of summer’s showy flowers—take center stage.
  • Roots halt their explorations and store up sugars to prepare for winter.
There is much to measure as plants prepare to take their long winter's rest, and CID Bio-Science can provide the tools you need to accurately quantify the way your plants are changing this season.

Field Notes: Seasonal Change in Carbon Sequestration
in the leaves of Red Oak, Maple, and Western Red Cedar trees
By Dr. Santokh Singh at University of British Columbia

The University of British Columbia's Social Ecological Economic Development Studies (SEEDS) is a program that brings together a team of students, faculty, and staff members to give students real-world experience working in sustainability. Undergraduate student Elgan Moses is currently working under the supervision of Dr. Santokh Singh and Senior Technical staff member Mr. Jarnail Mehroke in the Department of Botany at UBC. Their SEEDS project focuses on investigating the various physiological changes including carbon sequestration and transpiration rates in leaves of Red Oak, Maple and Western Red Cedar trees growing around the University of British Columbia (UBC), Vancouver, Canada. They are using the CI-340 Handheld Photosynthesis System to accurately measure these physiological parameters.

 

The project objective is to relate the net carbon sequestration rate and the transpiration rate in these tree species to the changing environmental conditions (e.g. temperature, light intensity, humidity, day length).

The results of this experiment will provide a better understanding of the impact of changing climatic conditions on the physiological performance, including carbon sequestration and transpiration in these tree species.
