Abstract: To clarify the adaptability of different oil-tea camellia species in tropical area, the introduction of oil-tea camellia in Chiang Mai province of Thailand was conducted and preliminary evaluated. The results showed that the C. vietnamensis and C. gaucowensis were most adaptable and the average survival rate were 92.5% and 92.7% respectively, secondly were, C. octopetala, C. polyodonta and C. oleifera and their survival rate were 40.0%, 66.7% and 46.6%, respectively. The C. semiserrata, C. mairei and C. chekiangoleosa were not successful in Thailand and they can not be planted in tropical area. In addition, the elevation was an important factor which could affect the growth of oil-tea camellia in tropical area. The survival rate, height, ground diameter, canopy and branching were quite different in trial sites with different elevation and the survival rate of C. oleifera, C. mairei, C. octopetala and C. semiserrata were higher in high elevation trial sites. The canopy of C. oleifera, C. mairei, C. octopetala and C. polyodonta were smaller in lower elevation trial sites. This study provided guidance of oil-tea camellia application and plantation in tropical area.
