Effects of clipping during autumn every 2 weeks for either three and six clipping cycles were compared to an unclipped control. Autumn herbage production of D. virgatus and D. heterocarpon was reduced by clipping, but that of G. elliottii was not. Root mass and non-structural carbohydrate concentration of roots and stem bases of D. virgatus and G. elliotii were reduced by clipping, while root mass of D. heterocarpon was unaffected by clipping. Root and stem-base carbohydrate accumulation of D. heterocarpon was greater for clipped plants than for the unclipped control.
