The purpose of this study is to examine the cold-resistance of Stenotaphrum secundatum. During growth response to the freezing treatment, the comparison of cold-resistance and the effect of hardening treatment were discussed between green leaf and variegated leaf plants. The plant growth under freezing condition was evaluated by the existing leaf number and leaf water potential. As a result, the temperature causing the wither and the damage on every kind were as follows: A tip of shoot was at -3°C, and a bottom of shoot was at -9°C, in green leaf plants. On the other hand, a tip of shoot was at 3°C, and a bottom of shoot was at -3°C, in variegated leaf plants. As the result of hardening treatment, green leaf existed at -11°C and variegated leaf existed at -7°C. These results suggest that the cold-resistance of variegated leaf is inferior to that of green leaf and hardening treatment contributes to increase of the cold-resistance in Stenotaphrum secundatum.
