Vertical distribution pattern of mixed root systems of desert plants Reaumuria soongarica and Salsola passerina under different environmental gradients

Aims How plant species interaction changes along environmental gradients has remained a hot issue in studies of species coexistence and biodiversity maintenance. This study was conducted to determine the responses of root systems to drought stress in desert Reaumuria soongarica-Salsola passerina communities, in order to better understand the interspecific relationships of plant communities in response to environmental stresses.
