title: [Comparison of leaf morphological characters among different major varieties of Rehmannia glutinosa].
abstract: OBJECTIVE
  To provide theoretical evidences for the identification and selective breeding of different major varieties of Rehmannia glutinosa by comparing their leaf characters such as the shapes, non-glandular hairs and the size and density of stomata.
  
  
  METHODS
  The length, width and the ratio of the length to the width of leaves were measured, and the density and length of the non-glandular hair, the density, size and density of the stomata in the epidermis were measured by scanning electron microscope.
  
  
  RESULTS
  The results showed that there were obvious differences in length, width and the ratio of the length to the width of leaves, the density and length of the non-glandular hair, the density and size of the stomata in the epidermis.
  
  
  CONCLUSIONS
  The morphological characters of the leaves mentioned above may serve as the identification standards of major varieties of R. glutinosa.
