| 摘 要： | 为了研究玉米灰斑病菌的产毒条件和致病机理，采用电导率法测定了静止培养下，以Fries培养液为基质，不同培养时间和培养温度下获得的玉米灰斑病菌毒素对离体玉米叶片电导率的影响。结果表明，相同培养温度和培养时间获得的玉米灰斑病菌毒素（浓度25%）处理不同时间对离体玉米叶片电导率的影响，主要随毒素处理时间的延长，电导率提高率表现为下降趋势；不同培养时间、不同培养温度获得的玉米灰斑病菌毒素对离体玉米叶片电导率均有明显的影响，(20±1)℃培养15天获得的玉米灰斑病菌毒素对离体叶片电导率的影响效果最理想。

| Abstract: | The toxin-generated conditions and the pathogenicity mechanism of Cercospora zeae-maydis have been studied in this article.The mensuration of conductivity method was used to examine the effects of C.zeae-maydis toxins statically cultured in the Fries nutrient fluid under different temperature and different time on the conductivity of maize leaves in vitro.The results showed that as processing time prolongs,the conductivity increasing rates on maize leaves in vitro decreased when treated with the C.zeae-mayd... |
