Abstract:Stipa krylovii in Inner Mongolia is a peculiar moderate-temperate steppe of the Central Asia Subzone. Affected by temperate continental climate, the obvious thermal difference due to latitude and the precipitation discrepancy due to monsoons provide the possibility of genetic diversity for S. krylovii in the region. Thus it is necessary to make a systematic study of population diversity at the individual, physiological, cellular or molecular levels. Seven plots, representative of the typical steppe, desert...
