| 摘 要： | 以改良Fries合成培养基为基础,观测氮饥饿胁迫条件下玉米大斑病菌菌株01-11和03-22在菌落生长速度、分生孢子产生时间和数量、菌落形态和颜色等方面的变化。结果发现,在缺氮条件下,培养6 d后菌落生长停滞,颜色变淡;菌丝稀疏,老化程度加快;分生孢子出现时间提前,但产孢数量减少。研究结果说明,氮元素对玉米大斑病菌的生长和发育有非常重要的作用。 |

| Abstract: | The colony morphology and growth speed,the conidia number and appearance time,and the mycelium color of Exserohilum turcicum(isolate 01-11 and 03-22) were studied on the improved Fries synthesis medium under the condition of nitrogen absence.The results had shown that after six days of nitrogen starvation,the mycelium growth was stopped,the colony color became darker,the mycelium biomass was reduced,the appearance time of conidia was promoted 2-3 days,but the conidia number decreased rapidly.It was proved that nitrogen played an important role on the growth and development of the corn pathogen. |
| Keywords: | Exserohilum turcicum Nitrogen starvation Growth and development |
