Since tomato contains both C- and N-based chemical defense compounds, we were able to monitor the effect of elevated CO2 in a single species, eliminating the need to compensate for interspecific differences. In this study we asked: 1) What effect does eCO2 have on constituitive concentrations of tomatine and of various phenolic compounds within the leaves and stems of tomato plants? 2) Can production of either group of compounds be systemically induced by mechanical damage. 3) If so, does eCO2 affect induction?http://deepblue.lib.umich.edu/bitstream/2027.42/55047/1/3491.pdfDescription of 3491.pdf : Access restricted to on-site users at the U-M Biological Station
