毛竹叶斑枯病是由竹独足座菌 [Coccostromaanundinariae(hara)Teng]侵染所致。菌落在PDA和竹煎汁培养基上生长较好 ,菌丝生长最适温度为 2 5～ 30℃ ,最适pH值为 6 .0。子座及子囊孢子的形成需要经光诱导 ,并且需要较低的温度 (10～ 15℃ ) ,pH值 3～ 11均能产生子囊孢子 ,pH值 8.5时产生子囊孢子的能力最强。在自然水条件下子囊孢子的萌发率 (39.2 % )较高 ,子囊孢子萌发 pH值以 2～10 ,最佳为 6 .5;竹煎汁培养基对孢子萌发有明显的促进作用
Phytoplankton is caused by the infection of Coccostromaanundinariae (hara) Teng. Colonies in PDA and bamboo juice medium growth is better, mycelial growth optimum temperature of 25 ~ 30 ℃, the optimum pH value of 6.0. The formation of zygotes and ascospores required light induction and required lower temperatures (10-15 ° C). Ascospores were produced at pH values of 3-11 and were most capable of producing ascospores at pH 8.5. Under natural water conditions, the ascospore germination rate was higher (39.2%), and the ascospore germination pH value was 2-10, the best was 6.5. The bamboo juice decoction medium had a significant promoting effect on spore germination
