摘要
为了明确山西省不同地区玉米大斑病之间存在的差异，分别从侯马、阳曲、静乐、屯留岭上4个地区采集到病叶标样，经单孢分离得到大斑病病菌，通过不同温度、光照及培养基，对这4个地区的大斑病菌种进行测定。结果表明，侯马地区分离的菌种菌丝适应温度范围最广，为10-35℃，其他菌株为15-30℃；在光照测试中，侯马地区在光照12h黑暗12h条件下培养，菌落有明显的同心等距离环纹，其他地区的菌种没有出现这种情况；从不同培养基测试中可以看出，侯马地区的菌种在不同培养基上都能快速生长，阳曲、静乐地区生长次之，屯留岭上地区的菌种生长最慢。
To identify northern corn leaf blight difference among the different regions in Shanxi, corn bleaf blight were collected from Houma, Yangqu, Jingle and Tunliulingshang for the test on the isolation.The different conditions had been compared in the experiment. The research results showed that the temperature for lhe Houma mycelial growth was from 10℃to 35 ℃,other myeelial were from 15 ℃ to 30℃. In lighting test of 12 hours light and darkness alternation the concentric equidistant ring were found for strain from Houma, but in others alternation did not occur. The results showed that the strain from Houma could grow on all kinds of euhure media, and it grew faster than the strains from Yangqu and Jingle, the strain from Tunliulingshang grew the slowest.
