Abstract: The effect of temperature on the infection and disease development of Chinese cabbage bacterial black rot (Xanthomonas campestris pv.campestris) during the disease resistance evaluation was discribed in the paper.The results demonstrated that the pathogen could complete its infection process after inoculated under the temperature of 15, 20, 25 and 30℃ kept in growth chamber for 48 hours and shifted to room temperature conditions 11 days later.The development sped up with the increasing of temperature.Under the above temperatures,this pathogen needed 35, 32, 27 or 8 days respectively to attain the disease index of 50.And the LD100 needed 41, 35,32, 32 days respectively.Therefore the increasing temperature could cut short the time of the disease development.In fact the disease index could be assessed about 8-10 day after inoculation under 25 or 30℃.

Key words: Black rot, Temperature, Infection and development, Chinese cabbage
