摘要/Abstract

Abstract: This paper studied the clonal architecture of two divergent Leymus chinensis types (grey-green type and yellow-green type) in Songnen grassland,and compared their internode length,spacer length,interbranching length,interbranching angle,and ramet population density and height under the same habitat.The results showed that there was no significant difference in these clonal characteristics except spacer length and ramet population density between the two types of L. chinensis,and yellow-green type,with less spacer length and more ramet density than grey-green type,should be more adaptable to the resourceful habitat.Moreover,the V-indices of the clonal architecture of two divergent L.chinensis types were all close to 1,and the difference was not significant.Therefore,both of the two types belonged to typical guerilla clonal plant.

Key words: Leymus chinensis, Clonal growth, Clonal architecture, Ecotype, Divergent type
