摘　　要：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℃适宜菌丝的生长,适宜孢子萌发的温度是20～25℃;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。Using Magnolia sieboldii leaf spot pathogen as the test ma-terials of different carbon and mtrogen 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 p H values for the my.celium growth and spore germination are 8 and 7, respectively.
