Abstract: The characteristics of clonal propagation and the seedling regeneration from root suckers of wild Prunus divaricata in four habitats were studied in this research. The result indicated that the density of the younger sprouting seedlings of Prunus divaricata in gully habitat was the highest; the following were forest floor,steep slope and gentle slope,successively. There were five age classes of sprouting seedlings,the proportion of seedlings reduced with increase of age class in different habitats. And the proportion of sprouting in steep slope habitat was the highest,and others successively were in sequence of forest floor,gully and gentle slope. The sprouting rate firstly increased and then decreased rapidly when maternal diameter of wild Prunus divaricata increased,and it reached maximum when the maternal diameter class isⅥ(20.0-23.0 cm). More than 85 percent of adventitious buds from root suckers mainly happened in the first and second soil layer in different habitat. There were significant difference in the distribution layer of root suckers regeneration,and the first soil layer (0-1 cm) had the highest proportion in all the four habitats. Along with sprouting seedlings aging,the mortality decreased gradually in all the four habitats,and the seedlings in the bottom of gully had the highest mortality.

Key words: wild Prunus divaricata, root sucker, age structure, mortality rate, Xinjiang
