One-year-old seedlings of Camellia oleifera, C. drupifera and C. semiserrata were used as experimental materials, and their physiological characteristics were investigated. The results showed that cholrophyll content and relative water content decreased, but the soluble protein content increased over time in three Camellia species. After treatment for 72 h, the chlorophyll content and soluble protein were extremely significant difference compared to control in C. drupifera, and decreased by 64.67% and increased of 705.67%, respectively. While the chlorophyll content and soluble protein content in C. oleifera compared with the control only decreased of 34.35% and increased of 443.10%, showing stronger cold resistance. According to principal components analysis (PCA), It was described that C. oleifera had the strongest resistance for cold stress, followed by C. semiserrata and C. drupifera.
