ABSTRACT = {Annual leaf segments of eight <i>Camellia</i> 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. The relationship between the processing temperature and the cell injury rate in <i>Camellia</i> showed a typical "S" shaped curve, following the Logistic model. The correlation coefficient was above 0.95. The semi-lethal high temperature LT<sub>50</sub> of the eight <i>Camellia</i> species, determined by the inflection point on the curve, varied from 50 to 57 LT<sub>50</sub> / °C, following the descending order: <i>Camellia oleifera</i> > <i>C. japonica</i> > <i>C. polyodonta</i> > <i>C. semiserrata</i> > <i>C. nitidissima</i> > <i>C. gigantocarpa</i> > <i>C. nanyongensis</i> ><i> C. vietnamensis</i>. The semi-lethal high temperature of C. oleifera was 56.8 °C, and that of <i>C. vietnamensis</i> was 50.6 °C. Results showed <i>C. oleifera</i> appeared as the best suitable species for introduction in high-heat zones. <i>Camellia vietnamensis</i> 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.},
