Responses of vegetative propagation of Reaumuria soongorica to grazing and fenced non‐grazing

摘要

Overgrazing has been resulting in serious degradation of grassland in northwest China.The present study was conducted to investigate overgrazing and fenced non‐grazing treatments on vegetative propagation performances of R.soongorica, one of the extensively distributed, dominant xerophile species in northwest China.The shrub has two kinds of vegetative propagation : split propagation and adventitious‐root propagation (Liu, et al, 1982 ; Zeng, et al.2002).
