This study was carried out to investigate the growth response of Pinus densiflora seedling to relatively high day temperature during the container culture in summer season. The experiment was performed with three maximum day temperature regimes, 30~35$^{circ}C$, 35~40$^{circ}C$ and above 40$^{circ}C$ in the PE house. The reduction in plant height was observed since 6 weeks after germination in the seedlings grown at relatively high day temperatures, especially the seedlings at above 40$^{circ}C$. High temperature also reduced the root collar diameter during growth of the seedlings, therefore 17.3% of the reduction was observed in the seedlings grown at above 40$^{circ}C$ compared with the seedlings at 30~35$^{circ}C$. The dry weight of the seedlings grown for 16 weeks was apparently reduced by elevated dat temperature in the PE house, and the seedlings at relatively high day temperature resulted in increased T/R ratio.
