- 摘要:
- 为了解大果榛子白粉病的发生规律,系统地研究了不同碳源、氮源、温度、光照、pH对大果榛子白粉病病菌无性孢子萌发的影响。结果表明:不同的碳、氮源处理中最适于大果榛子白粉病病菌无性孢子萌发的碳源为蔗糖,氮源为甘氨酸、硝酸铵；中性条件下适于孢子的萌发；孢子萌发适宜的温度为20℃；24 h全光照条件下更适宜孢子萌发。
- Abstract:
- In order to understand the occurrence regularity of Phyllactinia guttata in Corylus heterophylla×C.avellana of Jilin area,the effect of different carbon resource,nitrogen resource,temperature,light and pH on the asexual spores germination was researched systematically for Phyllactinia guttata in Corylus heterophylla×C.avellana.The results showed that the most suitable carbon for the germination of asexual spores was sucrose,the most suitable nitrogen resources was NH2CH2COOH and NH4NO3 under pH neutral conditions with the 15～25℃,and full light conditions for 24 h was more suitable for spore germination.
