Effects of spatial patchiness (homogeneous vs. patchy), temporal interval (low vs. high interval) in water supply and stolon severing (severing vs. no severing) on number of ramets (A,D) stolon mass (B,E) and biomass (C,F) of the whole clonal fragment (proximal plus distal part) of H. vulgaris and H. sibthorpioides. Bars and vertical lines are mean values (+s.e., n = 8).
