摘要:
大豆紫斑病菌在PDA培养基上生长速率最快,在大豆叶葡萄糖琼脂培养基和番茄培养基上产孢量比在PDA上高2倍,此病菌生长发育最适温度为25- 28℃ ,低于15℃或高于37℃均不适宜,在连续黑暗条件下有利于生长, pH4-9之间,均能生长和产孢,以pH= 7生长最适, pH= 7- 8产孢最多,分生孢子在葡萄糖液中萌发最好,在15- 40℃之间均能萌发,最适温度为30- 33℃ , pH= 3- 9之间均能萌发, pH= 7- 8萌发最好,黑暗条件有利萌发。
Abstract:
The rate of Cercospora kik uchii g row th was the fa stest o n PDA. The amount ofspo rula tion increased about 2 times o n soybea n leav es gluco seagar o r tomato ag ar thano n PDA. The temperature fo r the g row th and spo rula tion o f the pathog en w as 18-35℃ , wi th o ptimum of 25- 28℃ . Complete darkness fav oured g row th and sporulatio n.The pH v alues from pH 4 to 9, wi th optimun pH7 fo r g row th and pH7- 8 for sporulation.Co nidia of Cercospora kikuchii g ermina ted best in agar w ater.
