Resumo: 	Annual leaf segments of eight Camellia species were used to study the heat tolerance by an electrical conductivity method, in combination with a Logistic equation to ascertain the semi-lethal high temperature by fitting the cell injury rate curve. Te relationship between the processing temperature and the cell injury rate in Camellia showed a typical "S" shaped curve, following the Logistic model. Te correlation coeficient was above 0.95. Te semi-lethal high temperature LT50 of the eight Camellia species, determined by the infection point on the curve, varied from 50 to 57 LT50 / °C, following the descending order: Camellia oleifera &gt; C. japonica &gt; C. polyodonta &gt; C. semiserrata &gt; C. nitidissima &gt; C. gigantocarpa &gt; C. nanyongensis &gt; C. vietnamensis. Te semi-lethal high temperature of C. oleifera was 56.8 °C, and that of C. vietnamensis was 50.6 °C. Results showed C. oleifera appeared as the best suitable species for introduction in high-heat zones. Camellia vietnamensis appeared more suitable for planting in temperate regions at lower temperatures. These results can provide theoretical basis for breeding and introduction of heat-tolerant oil-tea cultivars.
