title: [Study on seed biological characteristics of Gentiana crassicaulis].
abstract: OBJECTIVE
  To study seed biological characteristics of Gentiana crassicaulis.
  
  
  METHODS
  The samples were collected from five localities, and the morphological observation, germination test and viability TTC test were carried out.
  
  
  RESULTS
  The seed morphological characters of all samples were similar to each other. The viability of all samples was similar to each other, but the germination rate of wild seed was the highest in all samples after stored for 8 months. Also, the seed energy of wild seed and sample 2008XR02 was higher than other three samples. There was no obvious correlation between thousand seed weight and germination rate.
  
  
  CONCLUSIONS
  The quality of wild seed and sample 2008XR02 was superior than that of the other three samples. The results can be used for basic data of in situ conservation and germplasm breeding of G. crassicaulis.
