Primary source [18] abstract: "Acclimation to CO2 enrichment was studied in maize plants grown to maturity in either 350 or 700 microl l/l CO2." Primary source [31] abstract: "The response of stomatal parameters of four rice cultivars to atmospheric elevated CO2 concentration (EC) was studied using open top chambers." Primary source [32] abstract: "The responses of pubescent birch (Betula pubescens Ehrh.) leaves to elevated levels of carbon dioxide and ozone were investigated…The seedlings were exposed to elevated levels of CO2 and CO2+O3 in open-top chambers over four growing seasons (1993–1996)." |

P.10344 left column bottom paragraph: "Consistent with [investigators'] hypothesis [they] report that a positive correlation between S and Earth's global atmospheric CO2 history (Fig. 4A) is mirrored by a negative correlation between D [stomatal density] and CO2 over hundreds of millions of years of plant evolution (Fig. 4B). The magnitude of change in S is far greater than, but consistent with, that observed in short-term CO2 experiments (Table 1). These short-term changes are presumably reflecting phenotypic plasticity (i.e., the limited range in magnitude of S resulting from the effect of changes in the environment on stomatal development within a single generation)." P.10345 right column bottom paragraph: "[Investigators'] analyses implicate long-term global atmospheric CO2 change as a continuous driver of increasing gwmax [maximum diffusive conductance to water vapor] and gcmax [maximum diffusive conductance to CO2] throughout the entire evolutionary history of vascular plants (Fig. 4C). The analyses identify a previously unrealized effect of CO2 on stomatal size that is consistent with the direction of change observed in plant CO2-enrichment experiments for a grass, C4 herb, and an angiosperm C3 tree (Table 1)." |
