摘要
黄瓜靶斑病菌在10～35℃下均能生长,以30℃左右最适。分生孢子萌发的温度范围为10～35℃,以25～30℃最适;同时要求90％以上的相对湿度,在水滴中萌发率最高。光照对菌丝生长有促进作用,但对孢子的产生有抑制作用,紫外线对孢子有杀伤作用。
The biological characteristic of Corynespora cassiicola were studied. Results showed that the hyphae could grow at the temperature range 10 - 35 ℃ ,and the optimum temperature was 30 ℃. The preferred temperature for spore germination was 10-35 ℃ , and the optimum range was 25 - 30 ℃. The germination needed a relative humidity of over 90% , and water drop was the optimum condition. Light could stimulate the hyphae growth, but inhibit the spore production. The spore can be killed by the ultraviolet light.
