Fig 4. The reproductive allocation expressed as spike biomass / reproductive tiller biomass ratio (SPIKE/TILLER; A), mature seed biomass / spike biomass ratio (SEED / SPIKE; B) and mature seed biomass / reproductive tiller biomass ratio (SEED / TILLER; C) of Leymus chinensis clones at five patch size categories.

Different zones of the same patch size category followed by the same letter did not differ significantly at P = 0.05.
