The Effects Of Elevated Co2 Levels On Broad Bean, Vicia Faba, Growth/Defense Tradeoffs, Harley B. Kitching
Honors College Theses
Atmospheric changes, associated with global climate change, are increasing at an unprecedented rate. Plants generally display higher rates of growth in response to elevated CO2 levels, but this response varies among species. In addition, very little is known about how plant growth/defense tradeoffs will be altered by increasing CO2 levels. By raising Broad bean, Vicia faba L., plants under ambient (400 ppm) and elevated (900 ppm) levels of CO2, it was shown that atmospheric composition directly altered plant growth/defense tradeoffs. Plants grown under elevated CO2 had lighter stem weights but greater numbers of extrafloral nectaries …
