Abstract:
 To identify the pathogens causing poplar stem rot in Hohhot of Inner Mongolia.Tissue isolation method was used to isolate fungi from poplar trees in Hohhot.The pathogenicities were verified based on Koch’s rule,morphological,and molecular biological methods were then used to identify the pathogenic fungi.Eight fungi were isolated,and 3 isolates named YSFL1,YSFL3 and YSFL4-2 were found to cause the typical canker symptoms.According to the colony characteristics and sporogenetic morphology,ITS and β-tubulin sequences,they were identified as Cryptosphaeria pullmanensis (YSFL1) and Cytospora chrysosperma (YSFL3,YSFL4-2).This study proved that the pathogens of poplar canker in Hohhot area belonged to C.pullmanensis and C.chrysosperma.This result enriched the diversity of poplar canker pathogens in China,and laid a foundation for the prevention and identification of poplar pathogens in Inner Mongolia.
