We are growing Ginkgo biloba plants under ambient (400 ppm) and elevated CO2 levels (600, 800, and 1000 ppm).
Our experiment helps us estimate CO2 levels in fossil atmospheres using fossil Ginkgo leaves we collect from the geologic record.
All 15 trees are male. The pollen organs and freshly growing leaves come out at about the same time.
Looking downward on a Ginkgo tree - the plant distributes its leaves to maximize light capture.
