The present study was conducted to investigate photosynthetic responses and growth performances of Liriodendron tulipifera, Betula costata, and Carpinus cordata seedlings growing under four different light regimes (full sun and 54~65%, 26~37%, 8~13% of full sun). L. tulipifera and B. costata showed the highest photosynthesis rate of 13.59, 16.29 μ㏖ CO₂ㆍm-²ㆍs-¹, respectively, at full sun. And photosynthesis ability and growth performances were decreased as increasing shade level in the above two species.
