要旨本文	This study examined the effects of extreme summer climate on the carbon allocation of one-year-old Quercus variabilis seedlings. Open-field experiments were conducted with three temperature levels (ambient: TC, ambient + 3 ℃: T3, ambient + 5 ℃: T5) and two precipitation levels (ambient: PC, drought: DR) in Korea. Environmental factors (leaf temperature and soil water content) and growth (relative growth rate of height: RGH and root-to-shoot ratio: R/S ratio) were measured, and their correlations were analyzed. In DR, RGH was negatively correlated with leaf temperature (R=-0.36, p=0.011), while in PC, RGH showed a positive trend with increasing leaf temperature (R=0.26, p=0.066). No significant correlations were observed in the R/S ratio among treatments. These results suggest that warming in drought conditions negatively affects height growth, while biomass allocation between aboveground and belowground may show similar patterns under short-term extreme climate.
