title: [Study on germination characteristic of seed of Dendranthema indicum].
abstract: OBJECTIVE
  To find out the optimum condition for the germination of seed of Dendranthema indicum by studying the effects of pretreatment,phytohormone and temperature on it, and offer the basis for its standardized culture.
  
  
  METHODS
  The seed purity, weight per 1000 seeds, seed moisture content and seed viability were determined. The germination of D. indicum seed was tested under following conditions: pretreatment (acid, base, warm water, boiling water), phytohormone (IBA, 6-BA, NAA) and treatments under different temperature (10, 20, 25, 30 degrees C).
  
  
  RESULTS
  The seed purity was 99.4%; The weight per 1000 seeds was 0.2941 g; The seed moisture content was 4.39%; The seed viability was 85.3%; The tests of pretreatment couldnt increase the germination of D. indicum seed; Phytohormone had limited effect on the germination of the seed; Temperature condition showed significant effects on the germination.
  
  
  CONCLUSIONS
  The optimum condition for the germination of the seed of D. indicum is 25 degrees C on filter paper.
