| This study was carried out to investigate the effect of minimum night temperature in the PE house on growth of seedlings of Pinus densiflora and Betula platyphylla in winter season. The experiment was performed with three minimum night temperature regimes,5~8$^{circ}C$, 10~13$^{circ}C$ and 15~18$^{circ}C$. The temperature regimes were maintained for 8 weeks (to April 6) after germination peak, and then were broken by increasing natural temperature. The temperature did not affect the germination rate but delayed the germination by 10 days. Height, root collar diameter growth, and dry weight of two species were reduced by relatively low night temperature. The reduction was more obvious in the dry weight of above the ground measured at 8 weeks after germination. The seedlings grown for 8 weeks at 5~8$^{circ}C$ showed the lowest T/R ratio. It was also observed that the height growth response in Betula platyphylla seedlings to relatively low temperature was more sensitive than Pinus densiflora. |
