Clonal morphology of Artemisia frigida in the grassland with different degradation
Overgrazing caused the degradation of grassland and affected the structure of plant communities.Grazing‐induced degradation leads to the essential resource for growth and reproduction of plants are heterogeneously distributed.Clonal growth enables chonal plants to vigorously spread in horizontal space in many stoloniferous and rhizomatous plants,the connections(i.e.,stolons and rhizomes)between the ramets may occupy patches differing in resource supply.Phenotypic plasticity is assumed to be a strategy for clonal plants to cope with resource heterogeneous environments.Clonal plants through clonal growth and chonal morphology to acquiere heterogeneously‐distributed resource efficiently.A.f rigida is a native perennial shrub that occurs primarily on degradated rangelands.It has the ability to produce offspring through clonal propagation and sexual reproduction.in degradated grassland.through its clonal growth it not only to acqire resource but also play important role in sand fixation and wind erosion control.
