Abstract
It is important to understand how woody species are affected by elevated in-soil CO2 for carbon capture and storage (CCS). Astudy was conducted to analyze the effects of artificially released in-soil CO2 on the physiology and growth of 4-year-old Pinus densifloraand 3-year-old Quercus variabilis seedlings. Approximately 7.9 kg CO2 plot–1 d–1 was released at a depth of 0.5 m over the period from20 June to 20 July 2017. For both species, chlorophyll fluorescence and content, photosynthetic rate, and leaf size significantly decreasedafter the CO2 release. However, stomatal behavior varied between these species under the elevated in-soil CO2 conditions. Elevatedin-soil CO2 inhibited plant physiological functions by limiting available in-soil O2. The leaf size of treatment plots showed significantlylower values of 0.60 ± 0.05 cm2 for P. densiflora and 12.05 ± 1.47 cm2 for Q. variabilis compared to those of control plots of 0.90 ± 0.09cm2 for P. densiflora and 21.84 ± 3.62 cm2 for Q. variabilis, whereas the number of leaves increased from 2697 ± 153 leaves to 3121 ±255 leaves for P. densiflora and from 95 ± 4 leaves to 288 ± 52 leaves for Q. variabilis. It was found that the decrease in leaf size resultedin a second flush, which increased the total leaf area per seedling. The biomass of P. densiflora significantly decreased in the treatmentplots (P < 0.05). Q. variabilis showed an increase in mortality, with a low percentage of fine root (
