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

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
