| Research Abstract |
In this study, we aimed to clarify the effect of elevated CO_2 on the defense ability of beech (Fagus crenata) to estimate long-term forest management under global climate change. Leaves of young beech trees grown at Free Air CO_2 Enrichment (FACE) system and control sites were taken during growing season during 2009-2011, and defense traits of leaves such as leaf mass per area (LMA), CN ratio, concentration of total phenolics and condensed tannin were analyzed. All defense traits were higher under elevated CO_2 compared to ambient CO_2 after leaf maturity on mid-June, in particular in 2011. These results indicated that changes in defense of beech leaves might affect the herbivory of specialists that emerge on August.
