Figures & Tables

Figure 1

Interaction effects of light intensity and concentration of CO2 on (A) DW of above-ground parts, (B) leaf DW, (C) total number of leaves, and (D) SLA of chrysanthemum. Plants were exposed to different concentrations of CO2 (400 ppm – black columns and 1,000 ppm – gray columns) and different light intensities (75, 150, 300, and 600 μmol·m−2·s−1 PPFD) Bars are mean value ± SEM and when the letters above the bars are similar, it means that they are not significantly different according to the ANOVA test at p ≤ 0.05; ANOVA – analysis of variance; DW – dry weight; PPFD – photosynthetic photon flux density; SLA – specific leaf area

Figure 2

Interaction effects of light intensity and concentration of CO2 on (A) root DW, (B) inflorescence DW, (C) number of inflorescences, and (D) the time of flowering of chrysanthemum. Plants were exposed to different concentrations of CO2 (400 ppm – black columns and 1,000 ppm – gray columns) and different light intensities (75, 150, 300, and 600 μmol·m−2·s−1 PPFD)Note: See Figure 1

Figure 3

Root system of chrysanthemum affected by light intensity and CO2 concentration. The plants were exposed to different concentrations of CO2 [400 ppm as ambient CO2 (a[CO2]) and 1,000 ppm as elevated CO2 (e[CO2])] and light intensities (75, 150, 300, and 600 μmol·m−2·s−1 PPFD)Note: See Figure 1

Figure 4

Interaction effect of light intensity and concentration of CO2 on the flowering of chrysanthemum. Plants were exposed to different concentrations of CO2 [400 ppm as ambient CO2 (a[CO2]) and 1,000 ppm as elevated CO2 (e[CO2])] and light intensities (75, 150, 300, and 600 μmol·m−2·s−1 PPFD)Note: See Figure 1

Figure 5

Diminishing effect of elevated CO2 (calculated as reduction in biomass accumulation in plants under e[CO2] compared to a[CO2]) on total biomass of chrysanthemum plants grown under different light intensities

Figure 6

Allocation of biomass (DW) to different organs in response to CO2 concentrations and light intensities. Plants were exposed to different concentrations of CO2 [400 ppm as ambient CO2 (a[CO2]) and 1,000 ppm as elevated CO2 (e[CO2])] and light intensities (75, 150, 300, and 600 μmol·m−2·s−1 PPFD)Note: See Figure 1

Figure 7

Interaction effect of light intensity and concentration of CO2 on water use efficiency (WUE) of chrysanthemum. Plants were exposed to different concentration of CO2 (400 ppm – black columns and 1,000 ppm – gray columns) and different light intensities (75, 150, 300, and 600 μmol·m−2·s−1 PPFD)Note: See Figure 1
