Primary Study on Reproduction Strategies of Caragana roborovskyi in the Arid Desert Region

To understand the reproductive characteristics and adaptation strategies of Caragana roborovskyi in the arid desert.The breeding tendency,clonal growth and ramets characteristics of C.roborovskyi in the Alshan desert region of the Inner Mongolia Plateau were studied.Results showed that C.roborovskyi propagated not only by asexual reproduction but also by sexual reproduction.The proportion of asexual reproduction(95.8%) was significantly higher than that of sexual reproduction(4.2%).C.roborovskyi produced ramets mainly by sprouted root and established clonal architecture known as Guerilla.Overall,C.roborovskyi adapted to both arid and barren environment of Alshan desert region by Guerilla clonal propagation and well-developed root system which determined it as the dominant species in the desert.
