- Description
- Stomatal density, in the form of a stomatal index
term, was calculated for six genotypes of Populus tremuloides. Two
variables, high and low soil fertility and elevated and ambient CO2
levels were used in conjunction with each other to form four
different treatments. Stomatal density, epidermal cell density,
stomatal length, and leaf area were all recorded. Stomatal index
decreased significantly at elevated CO2 levels. Stomatal index,
stomatal density and stomatal length differed significantly between
genotypes, but not in conjunction with response to elevated CO2.
Soil fertility and leaf area did not play significant roles in
response to elevated CO2.
