    摘要:

    通过研究不同温度、光照及pH值对杏斑点病菌菌丝、病原孢子生长的影响。结果表明,菌丝适宜在偏碱性条件下(pH在7~10间)生长;最适宜菌丝生长的温度为30℃;最适宜菌丝生长的光照条件是全光照。不同温度、pH值、光照对孢子萌发的影响为偏酸条件下(pH值4~7)更适宜孢子萌发;最适宜孢子萌发的温度为25~35℃;最适于孢子萌发的条件是全光照。

    Abstract:

    Effects of different temperature, light and pH on the mycelium growth and spore germination of Phyllosticta chlorospora McAlp of Prunus armeniaca L. were studied in the paper. The results showed that the optimum pH for mycelium growth was 7 to 10, the best temperature for mycelium growth was 30℃, and full sunlight was the most suitable for mycelium growth. The optimum pH for spore germination was 4 to 7, the optimum temperature for spore germination was 25℃ to 35℃, and full sunlight was the most suitable for spore germination.
