title: [Cluster analysis on hypocrellin A content in anamorphs of Shiraia bambusicola].
abstract: OBJECTIVE
  By examining the colony growth rate, colony texture, substrate mycelium color and separation method of 40 anamorph strains of Shiraia bambusicola to investigate the relationship between these indexes and content of hypocrellin A.
  
  
  METHODS
  In UV-spectrophotometry and microscopic observation were applied in the experiments. The results were analyzed by the clustering and variance analysis.
  
  
  RESULTS
  SPSS clustering analysis showed that the colony characters of S. bambusicola anamorph strains had significant differences with hypocrellin A content.
  
  
  CONCLUSIONS
  In the tested conditions, substrate mycelium color of S. bambusicola anamophs has the most distinct correlation with the yield of hypocrellin A.
