| 摘 要： | 为了进一步防治玉米灰斑病奠定基础,对西南地区玉蜀黍尾孢菌的生物学特性进行了初步研究。结果表明,该病菌生长温度为10～35℃,最适生长温度为20～25℃;病原菌对酸碱度的适应范围较广,在pH 4～11都能生长,以pH 5～7为最适pH值;分生孢子萌发温度为5～35℃,最适温度为20～25℃;光照对菌丝和孢子萌发无显著影响;病原菌最适碳源为葡萄糖,最适氮源为酵母膏,致死温度为55℃(10 min)。

| Abstract: | Some biological characters of Cercospora zeae-maydis were studied in this experiment.The results showed that the pathogen could grow and develop between 10 and 35 ℃,and the optimum temperature was between 20 and 25 ℃.For growth of the pathogen,there had no strict pH requirement: the favorable pH was 4-11 and the optimum pH was 5-7.For germination of conidia,the favorable temperature for conidial germination was between 5 and 35 ℃ and the optimum temperature was 20-25 ℃.Effect of light was not obvious on mycelial growth and conidial germination.The optimum carbon source was glucose,and the optimum nitrogen source wa s yeast extract.The lethal temperature for pathogen was at 55 ℃ for 10 minutes. |
