天女木兰叶斑病病菌生物学特性研究

以天女木兰叶斑病病菌为试材，研究不同碳、氮源对天女木兰叶斑病病菌生长的影响；试验结果表明：适合菌丝生长碳源是乳糖与葡萄糖；适合菌丝生长的氮源是硝酸铵；最适合孢子萌发的碳源是葡萄糖；适合孢子萌发的氮源是硝酸铵；25益适宜菌丝的生长，适宜孢子萌发的温度是20~25益；全光适宜菌丝的生长和孢子萌发。适合菌丝的生长和孢子萌发PH8与PH7。

Research on Leaf Spot Pathogen Biological Characteristics of Magnolia sieboldii

Using Magnolia sieboldii leaf spot pathogen as the test materials of different carbon and nitrogen sources on Magnolia leaf spot pathogen growth;the results show that:lactose and glucose is the carbon source for mycelial growth and ammonium nitrate is the nitrogen source;glucose is the most suitable carbon source for spore germination and ammonium nitrate is the nitrogen source;The suitable temperature for mycelial growth is 25℃ and for spore germination is 20~25℃;all-optical conditions suitable for mycelial growth and spore germination;the pH values for the mycelium growth and spore germination are 8 and 7,respectively.
