Effect of waterlogging on carbon isotope discrimination during photosynthesis in Larix gmelinii
Soil moisture is a major factor controlling carbon isotope discrimination (Δ 13 C), which has been demonstrated to decrease under dry conditions in many studies; however, few studies on Δ 13 C under waterlogging condition have been conducted. In this study, a pot experiment was conducted with Larix...

Soil moisture is a major factor controlling carbon isotope discrimination (Δ 13 C), which has been demonstrated to decrease under dry conditions in many studies; however, few studies on Δ 13 C under waterlogging condition have been conducted. In this study, a pot experiment was conducted with Larix gmelinii , a major larch species in the east Siberian Taiga, to investigate the effect of waterlogging on Δ 13 C during photosynthesis. Assimilation rate and Δ 13 C RD (instantaneous Δ 13 C calculated with Rayleigh distillation equation) decreased drastically soon after waterlogging, followed by recovery in their values, which was caused by a change in stomatal conductance. Thereafter, assimilation rate decreased gradually, whereas Δ 13 C RD decreased more gently. These results were thought to be caused by the decrease in both stomatal conductance and carboxylation. Our results indicate that extreme wet events may cause a decrease in Δ 13 C, which is important information for detecting flooding events in the past using tree-ring isotope analyses and for studying impacts of flooding on plants in areas where waterlogging might occur. |
